A cyclist attempts to climb a step starting from rest as shown in the diagram below. Assuming a gear ratio of 1, what is the minimum torque the cyclist must apply to the pedal in order to climb the step? The position of the combined center of gravity, G is located as shown. The wheels, which have negligible mass, have a radius r which is greater than the step height c. b C a=0.4m, b=0.5m, c=0.15m, h=0.75m, r=0.3m, m (combined mass)=80kg
