We want to implement a high pass filter with a corner frequency of 10 khz and an attenuation greater than 10db at 5 khz.

(a) plot in matlab the magnitude response of a 1 st order and 4th order high-pass filter with a corner frequency of 10 khz. be sure to include a screenshot of your code in your submission.
(b) what is the magnitude ratio at 5 khz for each filter

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

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

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false
