...angle of each force with the x-axis. This angle is called the reference angle, and is the one used to calculate sines and cosines. Next compute the x- and y-components of the three forces, placing like components in columns. Place plus or minus signs on the various quantities according to whether an x-component is to the right or left of the origin, or whether a y-component is up or down relative to the origin. Add the columns with regard to sign (subtracting the minus quantities), and place the correct sign on each sum. The resulting quantities are the x- and y-components of the resultant. Since they are forces at right angles to each other, they are combined by the Pythagorean Theorem. The angle of the resultant is found by the fact that the ratio of the y-component to the x-component is the tangent of the angle of the resultant with the x-axis. Make a new drawing showing the two components of the resultant along the x- and...

...of the lab period. Time cannot be given in lab to perform PreLab activities. After the start of lab activities, PreLabs cannot be accepted. Q1. What is the basic difference between scalars and vectors? Q2. Do the plus and minus signs that signify positive and negative temperatures imply that temperature is a vector quantity? Explain. Q3. Which of the following statements, if any, involves a vector? (a) My bank account shows a negative balance of –15 dollars. (b) I walked two miles due north along the beach. (c) I walked two miles along the beach. (d) I jumped off a cliff and hit the water traveling straight down at 17 miles per hour. (e) I jumped of a cliff and hit the water traveling at 17 miles per hour. Q4. Two vectors, A and B, are added by means of vector addition to give a resultant vector R: R = A + B. The magnitudes of A and B are 2 m and 7 m, respectively, and they can have any orientation. What are the maximum and minimum possible values for the magnitude of R? Q5. Top of Form Q5. During a relay race, runner A runs a certain distance and then hands off the baton to runner B, who runs a certain distance and hands off the baton to runner C, who runs a certain distance. In the four cases below, graphically add the three displacement vectors A, B and C together and draw the resultant vector R. A (a) (b) ...

...State the different types of mechanics? Depending upon the nature of the body involved, Mechanics can be classified into two types * Mechanics of Solids * Mechanics of Fluids Define Statics The study of a body which is in motion is known as statics Define Dynamics. The study of a body which is in motion is known as dynamics. Define Kinematics. It is the branch of dynamics which deals with the relationship between displacement, velocity, acceleration and time of a given motion, without considering the forces that cause the motion. Define Kinetics It is the branch of dynamics which deals with the relationship between the forces acting on a body, the mass of the body and the motion of the body. What do you understand from the concept of “Law of dimensional homogeneity”? Law of dimensional homogeneity states that “basic equation representing physical phenomenon must be valid for all systems of units”. State Parallelogram law. It states that “If two vectors acting at a point be represented in magnitude and direction by the two adjacent sides of a parallelogram, then their resultant is represented in magnitude and direction by the diagonal of the parallelogram passing through that point”. 2. 3. 4. 5. 6. 7. 8. 9. 10. State triangle law. It states that “It two vectors acting at a point are represented by the two...
