The value of resistance r was determined by measuring current I flowing through the resistance with an error E1=±1.5% and power loss p in it with an error E2=±1.0%. Determine the maximum possible relative error to be expected on measuring resistance r, calculated from the formula r=p/I²​

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
