Determine the max torque that can be applied to a bicycle crank arm . A fillet exists on the wall with a radius of 1/10". Please list any other assumtions you made to complete the problem.

1. assuming torque is only applied when pedal pushed down

2. assume constant torque for full rotation

Assume : Sut = 90kpsi, Sy = 50kpsi, Kf = Kfs = 1.7 , kd = ke = kf = 1

Fmin = 50 lbf
Fmax = 250 lbf
