Rotating Unbalance 5. A rotating machine of mass M = 100 kg is supported on four elastic mounts, each having a stiffness of k = 50,000 N/m and damping constant of c = 500 N-s/m. The machine is rotating at a speed of 6000 rpm and has an eccentric mass m = 0.005 kg located at a distance of e = 0.1 m from the axis of rotation. a. Determine the amplitude of vibration of the machine b. Determine the amplitude of the force transmitted to the base

Step 1
The machine rotates at 6000 rpm. To convert this to rad/s, use the formula: ω = (2π × rpm) / 60 ω = (2π × 6000) / 60 = 628.32 rad/s Show more…

A simplified model of a washing machine is shown. A bundle of wet clothes forms a weight $w_{b}$ of 20 lb in the machine and causes a rotating unbalance. The rotating weight is $\left.40 \text { lb (including } w_{b}\right)$ and the radius of the washer basket $e$ is 9 in. Knowing the washer has an equivalent spring constant $k=70$ lb/t and damping ratio $\zeta=c / c_{c}=0.05$ and during the spin cycle the drum rotates at 250 rpm, determine the amplitude of the motion and the magnitude of the force transmitted to the sides of the washing machine.
Mechanical Vibrations
Damped Vibrations
The spring system is connected to a crosshead that oscillates vertically when the wheel rotates with a constant angular velocity of $\omega .$ If the amplitude of the steady-state vibration is observed to be $400 \mathrm{mm}$, and the springs each have a stiffness of $k=2500 \mathrm{N} / \mathrm{m},$ determine the two possible values of $\omega$ at which the wheel must rotate. The block has a mass of $50 \mathrm{kg}$.
