Problem 7.7-1 the input to this circuit is the voltage source source voltage v ⁢ left-parenthesis t right-parenthesis equals 12 cosine left-parenthesis 30 ⁢ t right-parenthesis v the output is the current i left-parenthesis t right-parenthesis equals upper b ⁢ ⁢ sine left-parenthesis 30 t right-parenthesis ma. determine the value of the constant, b, used to describe the output current. b

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
