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

Anon25 [30]

Answer:

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

Step-by-step 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

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

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

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
