Acylindrical shaft made of steel of yield strength 700 mpa is subjected to static loads consisting of a bending moment of 10 kn-m and a torsional moment of 30 kn-m. determine the diameter of the shaft using two different theories of failure and assuming a factor of safety of 2.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
