A shaft is loaded in bending and torsion such that M_a = 600 lb-in, T_a = 400 lb-in, M_m = 500 lb-in, and T_m = 300 lb-in. For the shaft, S_u = 100 ksi and S_y = 80 ksi, and a fully adjusted endurance limit of S_e = 30 ksi. At a notch, K_f = 2.2 and K_fs = 1.8. With a design factor of 2.0, determine the minimum acceptable diameter, using a. Gerber, b. Goodman,

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

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

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
