Solve Prob. 19.C4, assuming that a dashpot having a coefficient of damping c = 2.5 kN · s/m has been connected to the motor base and to the ground.
Prob. 19.C4 A 15-kg motor is supported by four springs, each of constant Computer Problems 60 kN/m. The unbalance of the motor is equivalent to a mass of 20 g located 125 mm from the axis of rotation. Knowing that the motor is constrained to move vertically, use computational software to calculate and plot the amplitude of the vibration and the maximum acceleration of the motor for motor speeds of 1000 to 2500 rpm.
