Problem
A cyclist applies a 200N force on a pedal of a bicycle crank of fixed length. Consider two positions of the crank relative to the vertical:
Position P: the crank is horizontal.
Position Q: the crank is vertical.
Identify which position produces zero torque about the crank axis and state why.
