600 N Problem 5: Fatigue A bicycle crank experiences cyclic loading due to the force applied by the rider's feet. The maximum stress occurs at the angle shown. Assume the minimum stress is zero (the rider applies no force on the upstroke). The rider applies a force of 600 N. Neglect torsion in the crank. The crank is 165 mm long and has a rectangular 15 mm G 165 mm ☑ 12 mm cross-section with a width of 12 mm and height of 15 mm. It's made of steel: Sy = 290 MPa, Sut = 360 MPa, Se = 110 MPa, σ = 460 MPa, b = -0.1. a) Calculate the safety factor against yielding on the first pedal stroke using the max. shear stress criterion.
