A30 mm thick aisi 1020 steel plate is sandwiched between two 10 mm thick 2024-t3 aluminum plates and compressed with a bolt and nut. the bolt is m10 × 1.5 and the length of the bolt is 60 mm. determine: a) bolt stiffness (note: convert gpa to mpa. 1 gpa = 1000 mpa):

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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
