Question
A cyclist applies a force of 250 N to the pedals of a bicycle. If the rear wheel applies a force of 200 N to the road surface. What is the mechanical advantage of the bicycle?
Answers
M.A. = (delivered force)/(applied force)
= 0.80
What you lose in applied force, ratio-wise, you gain in speed.
= 0.80
