Chapter 8, Problem 8/134(choose chapter or problem)
The oscillator contains an unbalanced motor whose speed N in revolutions per minute can be varied. The oscillator is restrained in its horizontal motion by a spring of stiffness and by a viscous damper whose piston is resisted by a force of 30 N when moving at a speed of Determine the viscous damping factor and plot the magnification factor M for motor speeds from zero to 300 revolutions per minute. Determine the maximum value of M and the corresponding motor speed. 8/134
