Flexibility due to deflection of the pedals is not desirable. In the pedal shown, the pedal contacts the pedal spindle at two points. To lower the weight, spindles made of titanium have been considered, although their greater flexibility is viewed as a potential drawback. One detrimental consequence of deflection is that the rider may sense the rotation of the spindle and pedal due to bending. To estimate this effect, the spindle is approximated as having a uniform cross-section. Let a downward force of 250 lb on the pedal be divided equally between the two contact points. Determine the angle of rotation of the spindle midway between the contact points. Neglect any twisting of the crank. Let the titanium spindle have an outer diameter of 0.4 in. and an inner diameter of 0.2 in. Take the dimensions to be ![]()
