Question

The Geneva wheel is a mechanism for producing intermittent rotation. Pin P in the integral unit of wheel A and locking plate B engages the radial slots in wheel C thus turning wheel C one-fourth of a revolution for each revolution of the pin. At the engagement position shown, θ = 45°. For a constant clockwise angular velocity ω1 = 2 rad/s of wheel A, determine the angular acceleration α2 of wheel C for the instant when θ 20°. (16,5 rad/s²)
