A compound die is used to blank and punch a large washer out of 6061ST Al alloy sheet stock 3.2 mm thick. The outside diameter of the washer is 25.0 mm. and the inside diameter is 12.0 mm. Determine the force required to perform the blanking and punching operation under the following conditions: (a) blanking and punching occur simultaneously and (b) the punches are staggered so that punching occurs first, then blanking. The aluminum has a tensile strength of 350 MPa.

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

Prove the equivalence between the two statements of the 2nd law of thermodynamics (i.e., a violation of one statement leads to the violatio the other statement)

Which of the following is the most important advantage of a large field of view? a. allows larger areas to be examined b. relieves eyestrain c. minimizes parallax errors. d. increases precision in proportion to the in- crease in field of view
