... Therefore, the velocity ratio in the block and tackle system in Fig. 13b is 4. When designing the block and tackle system, a lighter pulley should be used because the weight of the movable pulleys will affect the efficiency. Furthermore, the rope or steel wire should not be twisted together. When us ...

... Compressors have gone through some dramatic internal design changes since the early days of automotive air conditioning. Overall, they are built much smaller and lighter than the units that were used on the older systems and no longer contain oil pumps. As a result, they have to depend on the flow o ...

Clutch
A clutch is a mechanical device that engages and disengages the power transmission, especially from driving shaft to driven shaft.Clutches are used whenever the transmission of power or motion must be controlled either in amount or over time (e.g., electric screwdrivers limit how much torque is transmitted through use of a clutch; clutches control whether automobiles transmit engine power to the wheels).In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member) while the other shaft (the driven member) provides output power for work. While typically the motions involved are rotary, linear clutches are also possible.In a torque-controlled drill, for instance, one shaft is driven by a motor and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at the same speed (engaged), locked together but spinning at different speeds (slipping), or unlocked and spinning at different speeds (disengaged).
