...Chapter 10. Uniform Circular Motion A PowerPoint Presentation by A PowerPoint Presentation by Paul E. Tippens, Professor of Physics Paul E. Tippens, Professor of Physics Southern Polytechnic State University Southern Polytechnic State University © 2007 Centripetal forces keep these children moving in a circular path. Objectives: After completing this module, you should be able to: • Apply your knowledge of centripetal acceleration and centripetal force to the solution of problems in circular motion. • Define and apply concepts of frequency and period, and relate them to linear speed. • Solve problems involving banking angles, the conical pendulum, and the vertical circle. Uniform Circular Motion Uniform circular motion is motion along a circular path in which there is no change in speed, only a change in direction. Fc v Constant velocity tangent to path. Constant force toward center. Question: Is there an outward force on the ball? Uniform Circular Motion (Cont.) The question of an outward force can be resolved by asking what happens when the string breaks! Ball moves tangent to v path, NOT outward as might be expected. When central force is removed, ball continues in straight line. Centripetal force is needed to change direction. Examples of Centripetal Force You are sitting on the seat next to You are sitting on the seat next to the outside door. What is the the outside door. What is the direction of...

...strategy of producing low cost and high quality products. It started on a program of acquisitions to meets its aggressive goals of growing sales 15% annually. It had acquired only financially successful companies. But in 1979, it acquired Skil Corporation, a financially mediocre and low performing company for $58 million. Skil was a leading manufacturer of portable power tools serving the professional and consumer markets, the circular saw being the strongest and best seller amongst those tools, which it also invented, and was amongst the top three in power tools market share holdings in U.S. Other power tools that Skil manufactured included mid-priced drills and roto hammers. Skil manufactured multiple different models for different countries, depending upon the local needs of the market. Under increasing competitive pressure, Skil’s financial results had not been high and attractive, although reported profitability had improved in recent years. It sold through all distribution channels but was well established in hardware stores and had a strong position in circular saws in contractor supply channels. Its sales force serviced all distributors except the mass merchandisers. Skil seldom advertised and relied more on product publicity. It sold tools on a worldwide basis, with its greatest international strength in Europe. Emerson has a task at hand to improve the market share of Skil Corporation given that the industry is saturated and has competitors like Black and Decker and Sears. Here...

...in November of 1832, and decided to draw out the money from the Bank (252). Unfortunately for Jackson, Nicholas Biddle, the Bank’s president, decided to call in loans, which “induced a massive recession [:]” businesses closed down, factories stood idle, retail districts had no buyers, and “interest rates offered to the brokers who flocked to New Orleans every fall to buy cotton harvest rose 25 percent” (253). Many citizens blamed Jackson for this catastrophe; yet, there were still more economic woes related to Jackson and the banks to come. The speculation of public lands added to this crisis, and Jackson’s subsequent issuing of what was known as the “Specie Circular”. As stated, banks issued paper money; yet, there existed high rates of speculation in these banks, particularly on federal lands. Thus, the Specie Circular issued by Jackson “declared that from August onward, only gold and silver would be accepted as payment for most government-owned lands” (272). This caused land sales to drop substantially, and banks had to begin charging “a premium for gold and silver, making everything else more expensive” (272). This caused many chain reactions, such as falling cotton prices and businesses going bankrupt. Demand for cotton also began to decrease, and “British-buying firms in Liverpool began to get nervous […] in the late 1836, it began denying credit to those firms” (273). Cotton began to free fall, and creditors from overseas began calling in the huge amounts of “debt owed...

...disappear. 2) Which color vector (arrow) represents velocity and which one represents acceleration? How can you tell? Acceleration is the green vector and velocity is the blue vector. For example, when you drag the ball slowly the blue vector is hardly seen because there is very little velocity when moving at a slow pace. The green vector is seen because this is acceleration which is a change in speed, which is happening at even a slow pace. 3) Try dragging the ball around and around in a circular path. What do you notice about the lengths and directions of the blue and green vectors? Describe their behavior in detail below. The lengths of the vectors seem to be close to the same length but the object is constantly changing its direction. The ball is moving tangent to the circle and the velocity vector is tangent to the circle as well. The ball is moving in the same direction as the velocity vector. The ball is undergoing a constant acceleration in this uniform circular motion. It is acceleration because it is changing direction, and the direction is...

...Explain, with the aid of appropriate diagrams, how the five sector circular flow of income interacts to generate economic activity. The circular flow model represents two flows: the real flow of production and the flow of money. The real flow refers to the flow of resources and goods and services within an economy. Firstly, the simple circular flow of income encompasses two closed sectors – firms and households, and two markets – the product and factor. Households sell resources, such as land, labour, capital and enterprise, to firms in the resource market, which then use the resources to produce goods and services, which are then sold back to households in the product market. Households receive income for their resources from firms through rent payments, wages, interest and profits, and they then use that income to purchase goods and services. This model represents a subsistence economy. However, the simple circular flow of income does not accurately represent the real world as there are many other sectors which contribute to economic activity. A closer approximation of the real world can be arrived at by adding injections and leakages to the model. Leakages are the losses from the flows, and injections are the additions back into the flows. Saving, taxes and imports are all leakages from the circular flow, which are matched by injections, which are investment, government spending and exports. We can now add three more sectors into our model: financial institutions, governments...

...Section 8.1 gives us a good background by defining several important terms. The center of a circular path defines a line called the axis of rotation. The angle that an object rotates about a fixed axis is called the angular displacement (). Counterclockwise displacement is considered positive, and clockwise negative. Angular displacement can be expressed in degrees, revolutions, or radians. A radian is the measure of the angle subtended by an arc that is the length of the given radius. 2 rad is equal to 360. Therefore, 1 rad is equal to 57.3. Section 8.2 discusses angular velocity . Average angular velocity is derived in a similar way to the average linear velocity we have already discussed. It is simply the angular displacement divided by the elapsed time, and it is usually measured in radians per second. This section also deals with the difference between instantaneous and average angular velocity. This is also analogous to what has already been discussed with linear velocity. Also similar to the concepts we have already dealt with in linear motion is the concept of angular acceleration (), which is simply a change in the angular velocity. Section 8.3 clarifies the equations (similar to those used in linear motion study) that are necessary to work problems dealing with angular motion. These are the equations of rotational kinematics for constant angular acceleration: = 0 + t = ½ (0 + )t = 0t + ½ t2 2 = 02 + 2 Also in this section...

...equipment and materials is of upmost importance when considering the layout. How easily will nurses and doctors get to the patients, and how much time will it take them to go from point “A” to point “B”? A hospital tends to be more process oriented and, therefore; should be designed as such. Work cells provide the ability for personnel to perform certain functions in one specific place. Another variable that hospitals need to consider in layout design is the family of the patient. Patients will have visitors – some more than others – and they must be able to have privacy and be able to visit with their loved one in a comfortable setting. 2. What are the advantages of the circular pod design over the traditional linear hallway layout found in most hospitals? One of the advantages of the circular pod design is that it keeps the work cells closer to the patients. The pod design allows for one centralized place for nurses and doctors to work from. Rather than having to travel down long linear hallways, physicians and nurses are able to be closer to the patients and their equipment. 3. During a period of random observation, nurse Thomas Smith’s day includes 6 trips from the nursing station to each of the 12 patient...

...Lab Investigation Purpose: This lab will verify how the centripetal force on a rotating body is affected by the following variables: frequency, speed, mass, and radius of a rotating object. Available Materials: ● 2 rubber stoppers ● 28 steel washers ● reinforced ceramic tube ● 1.5 m of thread or string ● metre stick ● stop watch [pic] Lab Procedure: Remember that a proper scientific method requires identifying the following for each case of the investigation: → Independent Variable → Dependent Variable → Controlled Variables PART A - Centripetal Force vs Frequency 1. Set up apparatus as illustrated above. Measure 1.0 meter of string from the rubber stopper to the tube (held vertically) using the metre stick. Attach a piece of tape on the string about 1 cm below the bottom of the tube (see diagram pg. 152). This will act as a reference mark. 2. Place 12 washers on the end of the string (using the paper clip). 3. While holding the bottom stack of washers, whirl the rubber stopper in a horizontal circle above your head. Carefully adjust the speed of rotation until you feel very little tension on the string suspending the washers. Let go of the stack of washers and maintain the rotation rate so that the reference tape on the string remains stationary about 1 cm below the tube. Have a lab partner determine the time for 20 complete rotations. 4. Set...

...at work. Who is at fault here, the company or Mr. John Schmidt? Problems to be examined are the functioning of the safety guards presently on the table saw being used in the production shop, how employees are trained to operate this equipment and are the equipment conditions well. I will examine what was said by all the employees and management in the production shop. In this dispute it is examined if the company or the employee is at fault. Safety is number one when operating table saws in the work place and in the home. If you are not paying close attention to the process of cutting wood, the safety guards may not protect you in certain situations with handling table saws. According to woodworking machinery expert, Les Winter, the circular blades on the table saw move at a speed of 100 miles per hour. This can cause serious hazards to happen when operator is being careless and not focused on the operation of the saw. The smallest distraction or kickback can cause an accident. But even when all safety precautions are taken some accidents are still bond to happen because of human error or just randomly happen when all safety mechanisms are in use. The safety report, with this company, states that the safety guard was poorly designed to protect operators in a number of circumstances. The foreman,...

...A Universal Definition of Small Enterprise: A Procrustean bed for SMEs? SUBMITTED BY KHRYSTYNA KUSHNIR ON WED, 2010-08-11 11:43 Editor's Note: Khrystyna Kushnir is a consultant on micro, small and medium-sized enterprises with the Enterprise Analysis Unit of the World Bank Group. At the G-20 summit in Pittsburgh last year, the assembled authorities agreed to "scale up successful models of small and medium-sized enterprise (SME) financing." The G-20 assigned the IFC and other international organizations to launch a G-20 Financial Inclusion Experts Group and asked the private sector to come up with ideas through G-20 SME Finance Challenge. This increased attention to micro, small and medium-sized enterprises (MSMEs) begs the question -- what, exactly, should be considered an MSME? With the issue of MSMEs playing out on an international level, it is tempting to try to find a universal MSME definition. A universal MSME definition would ease the design of loans, investments, grants and statistical research. One such effort is IFC’s SME Definition Deep-dive Analysis and Recommendations, although it's currently on hold because of internal restructuring. As part of the G-20 follow-up work, IFC is currently working on a 2010 update of the Micro, Small, and Medium Enterprises: A Collection of Published Data. While recording the various definitions of MSME used in 120+ of the most populous world economies, I was struck by the wide range of approaches governments take to define what...
