Consider a front loader washer that weighs 200 lb with a 6 lb towels. The size of the drum is 0.4 m. During a spin cycle, the drum speeds from 0 to the operating speed of 700 rpm. Model the towels as one concentrated mass. Then, the equation of motion is given by Mx(double dot on the x)+cx(single dot on x)+kx=me(omega r square)sin(omega r t) let M: mass of
a.) What is the max. vertical response amplitude of the fan during ramp up?
b.) What is the vertical response amplitude of the fan at the operating speed?
