Thanks,

A bicyclist weighing 71 kg starts his ride by putting all his weight on one pedal. The pedal arm is

15 cm long and is initially positioned up at an angle of 31° from the perpendicular.

a. Sketch the pedal and draw the forces acting on it. Calculate the torque initially generated by

the rider.

b. Under the same conditions, how much torque is generated if the pedal arm is horizontal?

c. The material of the pedal arms is only rated for a maximum torque of 250 Nm. What is the

maximum weight of a rider that this bicycle can withstand?
