Effects of imbalance in machine
1. Imbalance imparts vibratory motion to the frame of the machine.
2. Produces noise which leads to human discomfort.
3. Detrimental effects on the machine performance & structural integrity of the machine foundation.
Uniform Wear theory:
When the product of pressure and area of the contacting surface transmitting load is taken as constant to determine the axial force & torque, it is termed as uniform wear theory as it is assumed that wear along the surface is uniform.
A freewheel mechanism on a bicycle allows the rear wheel to turn faster than the pedals. If there is no freewheel on a bicycle, a simple ride could be exhausting, because one could never stop pumping the pedals. And going downhill would be downright dangerous, because the pedals would turn on their own, faster than one could keep up with them.
