In a Geneva mechanism, the pin of the driving wheel exerts a contacting force against the slot of the driven wheel. Determine this force for the following data: driver speed, 400 rpm (constant); center distance of the wheels, 4 in.; pin location, on 3-in. radius; number of slots, 4; phase, pin radius at 30° form line of wheel centers; weight of driven wheel, 1 lb; radius gyration of driven wheel, 1 in. Determine the pin force due to inertia of the driven wheel, and determine the torque on the driving shaft.
