Example 2.4: A Two-Wire DC Distributor AB is fed from both ends. At Feeding Point A, the Voltage is maintained as at 230 V and at B, 235 V. The total length of the Distributor is 200 meters and Loads are tapped off as under: • The Resistance per kilometer of one conductor is 0.3 Ω. Calculate: A. Currents in various sections of the Distributor. B. Minimum Voltage and the point at which it occurs. 25 A at 50 meters from A 50 A at 75 meters from A 30 A at 100 meters from A 40 A at 150 meters from A

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
