Question

A centrifugal fan weighs 100 lb and has a rotating unbalance of 20 lb-in. When dampers having. damping factor , = 0.2 are used, specify the springs for mounting such that only .10% of the unbalance force is transmitted to the floor. Also, determine the magnitude of the transmitted force. The fan is running at constant speed of 1000 rpm.

Step 1

The fan speed is 1000 rpm. \[ \omega = \frac{1000 \times 2\pi}{60} \approx 104.72 \, \text{rad/s} \] Show more…

A centrifugal fan weighs 100 lb and has a rotating unbalance of 20 lb-in. When dampers with a damping factor of 0.2 are used, specify the springs for mounting such that only 10% of the unbalance force is transmitted to the floor. Also, determine the magnitude of the transmitted force. The fan is running at a constant speed of 1000 rpm.
