Homework Answers
A.False because for a body in equilibrium i.e. total force = 0 i.e. net torque about every point is zero i.e. it doesn't depend on any point specifically.
B. False for the same reason as A .
C. True , use torque = r × F

4. Tension in Drawbridge Chain A single chain is used to raise the draw bridge in a castle. In this problem we will examine the chain tension when the drawbridge is stationary at an angle of 45° with respect to the horizontal. Assume that the chain is also at 45° with respect to horizontal, and the chain...

To understand two different techniques for computing the torque on an object due to an applied force.Imagine an object with a pivot point p at the origin of the coordinate system shown (Figure 1). The force vector F⃗ lies in the xy plane, and this force of magnitude F acts on the object at a point in the xy plane. The vector r⃗ is the position vector relative to the pivot point p to the point where F⃗ is applied.The torque on the...
