Question
Explain which principle is involved in machine belts.
✓
Answer
In many machines (like flour mills), belts are used to drive wheels for running the machines. Greater friction is required between the belts and machine wheels, so that the belts can drive the machine wheels properly without slipping off wheels. So, in order to increase friction, machine belts are made up of special materials having rough surfaces.
