A simplified model of a washing machine is illustrated in the figure below. A bundle of wet clothes forms a mass of 1 kg (m,) in the machine and causes

a rotating unbalance. The total mass of the washer includes the clothes is 20 kg (M) and the radius of the washer basket (e)is 0.25 m. Assume that the spin cycle rotates at 300 rpm. Let K be 1000 N/m and (=0.01. a.) Calculate the magnitude of the unbalance force causing the vibration of the machine. b.) What percent of the above force is transmitted to the foundation? c.) Calculate the magnitude of the force transmitted into the foundation? d.) Suggest and EXPLAIN two ways of reducing the force transmission to the foundation without altering the speed of the spin cycle.i.)
