Question

The clutch linkage on a vehicle has an overall advantage of 24:1. If the pressure plate applies a force of 504lb,how much force must the driver apply to release the clutch.

Answer 1

the force that must be applied by the driver to release the clutch is 21 lb

Explanation:

Data provided:

clutch linkage on a vehicle has an overall advantage = 24:1

Applied force by the pressure plate = 504 lb

Now,

the advantage ratio is given as:

advantage ratio =
`\frac{\textup{Force applied by the pressure plate}}{\textup{Force applied by the driver}}`

on substituting the respective values, we get

`\frac{\textup{24}}{\textup{1}}` =
`\frac{\textup{504 lb}}{\textup{Force applied by the driver}}`

or

Force applied by the driver to release the clutch =
`\frac{\textup{504 lb}}{\textup24}}`

or

Force applied by the driver to release the clutch = 21 lb

Hence,

the force that must be applied by the driver to release the clutch is 21 lb
