Question:

To calculate the effects of rotating unbalance, we need to know the value of the product mu€, where mu is the unbalanced mass and € is the eccentricity. These two quantities are sometimes difficult to calculate separately, but sometimes an experiment can be performed to estimate the product mu€. An experiment was performed on a particular rotating machine whose mass is 75 kg. The machine's support has negligible damping and a stiffness of k = 2500 N/m. When the machine operates at 200 rpm, the measured force transmitted to the foundation was 15 N. Estimate the value of mu€.
