Design a voltage clamp that limits the output voltage of an input signal to +7.5 volts. Assume that you have a 15 volt power supply, that your signal source has a 50 Ω output impedance and that your load has an input impedance of 50 kΩ. You want to pass signal frequencies of 20 Hz and higher. (Hint: see Lab 3, exercise 3.5.)

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
