7. When a rigid body rotates about a fixed axis, every particle in the body moves in a circular path. As shown in the figure below, the arclength As between the angular positions 6, and 82 is given as As = rA8. Do you agree with this equation? rotational motion (a) In the limit where A6 is very small, then As can be consider as a straight line. Is this true or false? AsrAe (b) It follows from statement (a) that any points along the circular path there is a tangential velocity (vr) that is always perpendicular to the radius of the rotating body. Hence, if we divide both sides of the equation As = rAe by At, justify that we will get v = rw. This result indicates that the direction of the particle's velocity is tangential to its circular path at each point. Most importantly, for example, this result tells us the relation- ship between the angular velocity of the wheel of the car and linear velocity of the car. Reference line At (c) If the angular velocity changes by Aw, then the rotating…

1. Calculate the torque about the z-axis pointing out of the page at the origin in the following - figure given that F₁ =3 N, F₂ = 9 N, F3=8 N, F₁=2 N. Hint: Use the sign convention for torques, counter-clockwise rotation corresponds to a torque in the positive z-direction and clockwise rotation corresponds to a torque in the negative z-direction. Which forces produce clockwise rotations and which forces produce counter-clockwise rotations?
