In AP8.3 take k = 20 N/m . Also compute the amplitude of vibration that the mass M experiences if the sinusoidal excitation represents potholes 15 cm deep, spaced 20 cm apart and the speed of the vehicle is 8 km/h . At what speed is the vibration felt the most? 1 Drop-o Location: 2nd oor of EG in front of elevator 1...
