Derive equations that describe the angular displacement and angular velocity of the driven member of a Geneva mechanism (Fig. 2 .35) from the point where the driving pin engages the driven wheel to the point of disengagement. Find β = f(a) and dβ/ da. = f(u), and use (dβ/da)(da./dr) = dβ/dτ to determine an equation for the angular velocity of the driven member.
