Textbook Question
Chapter 10, Problem 1MCP
You are designing a wheel that must have a fixed mass and diameter, but that can have its mass distributed in various uniform ways. If the torque you exert on it is also fixed, which of the wheels shown in Figure 10.36 will have the smallest

Three forces are applied to a wheel of radius 0.350 mm, as shown in the figure below. One force is perpendicular to the rim, one is tangent to it, and the other one makes a 40.0∘∘ angle with the radius. Let F1=12.4N, F2=14.2N, and F3=8.50N.
1) What is the net torque on the wheel due to these three forces for an axis perpendicular to the wheel and passing through its center? Let counterclockwise torques be positive.
Express your answer in newton-meters.
Suppose you start an antique car by exerting a force of 290 N on its crank for 0.13 s.
Variables:f = 290 Nt = 0.13 sd = 0.32 m
What angular momentum is given to the engine if the handle of the crank is 0.32 m from the pivot and the force is exerted to create maximum torque the entire time?
If torque is a vector, with a specific direction in space, what is meant by clockwise and counterclockwise torques? If the sums of these torques on a rigid body are equal, what does this imply physically?
