EXPERIMENT NO. 2
TITLE: FORCE VECTORS: GRAPHICAL AND ANALYTICAL METHOD
OBJECTIVES: To study force as vector and to use graphical and analytical method to determine the resultants of several forces.
APPARATUS: Force table, Weight hangers, Platform balance, set of masses, ruler, and protractor.
THEORY:
(a.) Analytical Method.
Analytical methods of vector addition and subtraction employ geometry and simple trigonometry rather than the ruler and protractor of graphical methods. Part of the graphical technique is retained, because vectors are still represented by arrows for easy visualization. However, analytical methods are more concise, accurate, and precise than graphical methods, which are limited by the accuracy with which a drawing can be made. Analytical methods are limited only by the accuracy and precision with which physical quantities are known. Analytical methods involve calculating answers without the use of charts or graphs. If one were to solve a system of equations by substitution, this would be an example of an analytically produced solution.
Analytical techniques and right triangles go hand-in-hand in physics because (among other things) motions along perpendicular directions are independent. We very often need to separate a vector into perpendicular components. For example, given a vector likeA in Figure, we may wish to find which two perpendicular vectors, Ax and Ay, add to produce it.

The vector A, with its tail at the origin of an x, y-coordinate system, is shown together with its x- and y-components, Ax and Ay. These vectors form a right triangle. The analytical relationships among these vectors are summarized below. Ax and Ay are defined to be the components of A along the x- and y-axes. The three vectors A, Ax, and Ay form a right triangle:
Ax + Ay = A. If the perpendicular components Ax and Ay of a vector A are known, then A can also be found analytically. To find the magnitude A and direction θ of a vector from its perpendicular components Ax and Ay, we use the following relationships:
A=Ax2+Ay2−−−−−−−−√
θ=tan−1(Ay/Ax).

(b.) Graphical Method.

Graphical method in physics is nothing but representation of vector addition. A vector quantity could be represented by an arrow tipped line segment. The length of the line, drawn to scale, represents the resultant magnitude of the quantity.

Whereas the working direction of the arrow indicates the direction of the quantity. This arrow tipped line segment would represent a vector and as we could represent a vector graphically, we could add vectors graphically as well. So far we have looked at motion in only one dimension, but vectors can also be represented in two dimension and especially motion. We could see these in examples where a person starts from one point A and starts walking due west 90 m and then due north to B for another 60 m. the vectors are added by placing the end point of one vector at the head of the other vector. The resultant of A and B are drawn from the tail of first vector to the head of the second vector. To find the magnitude of the resultant, R, we need to measure its length using the same scale used to draw A and B and then we might use trigonometric rulings to find the resultant or use Pythagorean formula. Force vectors are added in same way as position or velocity vectors. For example a force of A of 45 N and a force of B of 65 N are exerted on an object at point P. force A acts in a direction of 60 degrees and force acts at zero degree. The resultant R is the sum of two forces. R is found by moving A without changing its direction or length until the tail of A is located at the head of B.

Graphical methods involve examining charts, pictures, and graphs to determine the answer to a problem. This would be used when finding the solution to a system of equations and graphing all the equations to find points at which they coincide.

PROCEDURE: 1. Set the ring on the center of the force table and tie the strings on the ring. 2. Weigh the hangers and attach them to the string. 3. Make the string pass thru the required direction by adjusting the location of the pulley thru which each of the string passes. Place the required load on each hanger. 4. Place the load on the fourth hanger (the equilibrant) and adjust the location of the string by shifting the location of the pulley thru which it pass over at the same time by adjusting the load until the pin is centered on the ring. Record the load and the direction of the equilibrant. 5. Find analytically the resultant of the forces using the component method. Also find the direction of the said resultant. 6. Using the parallelogram method, find graphically the magnitude and direction of the resultant. 7. Find the numerical error and percent error.

VECTORS: GRAPHICAL AND ANALYTICAL METHOD COMPUTATIONS
F1=0.72 N 70⁰
F2=2.09 N 140⁰ = 0.25 N + (- 1.60 N) + (- 0.46 N)
F3=2.17 N 257.7⁰ Find the value of Fx and Fy: y = F1y + F2y + F3y
F1x = F1cos =(0.68 N) + 1.34 N + (-2.12 N) =0.72(cos 70⁰)
F1x = 0.25 N R = F1y = F1 sin = =0.72(sin 70⁰) R =1.81 N
F1y = 0.68 N
F2x = F2 cos = 2.09(cos 140⁰) =3⁰ 9’ 13’ 44.27” F2x = -1.60 N or
F2y = F2 sin β= 360⁰ - 3⁰ 9’ 44.27” =2.09 (sin 140⁰) =356⁰ 34’ 46.24”
F2y = 1.34 N
F3x= F3 cos = 2.17 (cos 257.7⁰)
F3x= -0.46 N
F3y = F3 sin = 2.17 (sin 257.7⁰)
F3y = -2.12 N

Graphical Method :

CONCLUSIONS: In this experiment, it aims to target the resultant vector of a moving object by the use of analytical and graphical method. In analytical method, you are just going to get the summation of function x as equal to the weight of the object times the cosine teta of the given angle. Also, the summation of function y as equal to the weight of the object times the sine teta of the given angle. Then you will solve the resultant vector that is equal to the square root of the summation of function x squared added to the summation of function y. While in the other hand, using graphical method is, you are going to plot and draw the distances with their angle in order to show the graphical method you have been giving. Within this two method used, it is preferably for me to use the analytical method because it is easier to calculate and solve the summation and the resultant vector of an object in order to get a precise number of a given problem. While using graphical method, you are going plot the distances and angle of the given problem.

...About Miloni we already knew that she has an artistic personality and would do the task allotted to her with perfection. We knew that conflicts would be there when a new group is formed because people feel it difficult to get out of their comfort zone and for introverts it’s even more difficult. So all of us knew to avoid conflicts we focused on our individual strengths and we aligned our goals with the goals of the group. We focussed on being the group that delivers the best performance as we were one of the groups who were underrated. All of us kept our group’s interest above our own individual interest. And no matter what we finished all of our group reports on time , every time . The members of the group didn’t bother even if our individual reports are not submitted. Members prioritised the group report above individual reports which helped better functioning and performance of the group. This seems quite an ideal situation but this is how it happened. It seems like magic. There was forming, No storming (only brainstorming) , Norming and...

How to Write a Report

...ENHANCE YOUR REPORT IMAGE Whether in school or on the job, you must prepare and present reports. Written reports create an image of you – on paper. To achieve the most positive image, written reports must be prepared carefully and presented forcefully. To prepare an excellent report, Clippinger (1995, 11-12) suggest five equally vital steps that must be taken in the order listed: (1) plan; (2) draft; (3) revise; (4) edit; (5) format. Plan the Report To plan, ask: What is my purpose for writing, and what is the reader’s purpose for reading what I write? The answers become the core of the message. Compose and key the core idea. Then as they come to mind through listening, reading, and thinking, jot (on the computer screen) ideas and facts that related to the core idea. Next, check the list for missing items (and add them), unneeded items (and delete them), and redundant items (and combine them). Put the items in psychological order (main point followed by details, usually) and arranged them logically (in chronological, geographical, or importance order, for example). Finally, check the list to see that the items are tied together and related to the core idea. When appropriate, use tables, charts, or graphs to condense data; then list only summaries of what the visuals reveal in greater detail. Draft the Message To draft or compose the message, pretend that the reader is sitting before you. Write (at the keyboard) as you would talk with that person (level...

Guide for Report Writing

...What is a report? A report ‘reports’ on something in a concise, formal way using clearly defined sections presented in a standard format, which tell the reader what you did, why and how you did it and what you found. It is the formal writing up of a practical experiment, project or research investigation. A report is written in a way which presumes that the reader knows nothing about your experiment or research. It is usually written more concisely than an essay, with headings and sub-headings and perhaps bullet-point recommendations, etc. A research report must be written in sufficient detail so that someone reading it would be able to replicate your research exactly. It usually contains arguments and critical evaluation to support a proposed course of action, or to evaluate a business issue. BEFORE YOU START WRITING… • Firstly, check with your lecturer and the module handbook for precise instructions, i.e. the prescribed report structure, word count, deadline. All UHBS reports are module and assignment specific, so this guide only gives a very general idea of structure and content. • Be very detail minded. All UHBS reports will require accurate referencing, good clear English, professional presentation, i.e. clear structure, coherent, free of spelling, grammatical and punctuation errors. • If you are compiling a group report, assign roles. One person in the group could be assigned the role of ‘editor’ to finally ensure the report is put together...
