1. The figure shows a sectional view of a clutch. The pressure on the clutch plate p = 180 lcPa is distributed over an annular area of inside radius of 75 mm and outer radius of 150 mm. Using appropriate free-body diagrams and equilibrium equations, determine the force F required to maintain the position shown.

4. Assuming no frictional losses, a torque of T = 750 lb.in is applied through the shaft of gear F in order to drive the roller chain at point B at a constant speed. The chain sprocket has a pitch diameter of 6 in and transmits a force of 500 lb as shown. The pitch diameters of gears C and F are 10 and 5 in, re-spectively. The contact force between the gears is transmitted through the pressure angle 4 = 20° Considering the bearing supports to be simple supports, determine the reactions at A, D, E, and G.
