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.

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 =

on substituting the respective values, we get

 =

or

Force applied by the driver to release the clutch =

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

answer: (1,3) and (-2,0) i think.
