An electronic instrument is to be isolated from a panel that vibrates at frequencies ranging from 25 hz to 35 hz. it is estimated that at least 80 percent vibration isolation must be achieved to prevent damage to the instrument. if the instrument weights 85 n, find the static deflection of the isolator.

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.
