The center post B of the assembly has an original length of 124.7mm, whereas posts A and C have a length of 125 mm. If the caps on the top and bottom can be considered rigid, what is the magnitude of the sum of the forces exerted by bars A, B, and C on the top plate? The posts are made of aluminum and have a cross-sectional area of 400 mm2. Eal=70 GPa. Answer should be in kN.

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
