There are two possible choices for the direction of , \widehat{n} the vector normal to the detector coil plane. the magnetic flux depends on the dot product {\overrightarrow{b}}\cdot \widehat{n} , so the sign of the flux depends on the direction chosen for \widehat{n}. does the choice matter? if so, how do you decide which one to use?

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
