The L-point averaging filter is a lowpass filter. Its passband width is controlled by L, being inverselyproportional to L. It is also possible to create a filter whose passband is centered around some frequencyother than zero. One simple way to do this is to define the impulse response of an L-point FIR as:

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

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
