15.1 INTRODUCTION
Power transmission is a process to transmit motion from one shaft to another by using some connection between them like belt, rope, chain, and gears. To connect the shafts, mainly two types of connectors are used, one is flexible and other is rigid. In flexible types of connection, there is relative velocity between shaft and connectors due to slip and strain produced in the connectors. But in case of rigid connection, there is no relative velocity between the connector and shaft.
Belt, rope, and chain are flexible connectors where gears are rigid connectors. Generally, belt, rope, and chain ...
