According to a settlement analysis conducted using the techniques described in Chapter 8, a certain mat will have a total settlement of 2.1 in if the average bearing pressure is 5500 lb/ft2. Compute the average ks and express your answer in units of lb/in3. (30 pts).

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
