Question
If the mechanical advantage of the handle of the pump plunger is 8, calculate the force applied at the end of the handle of the pump plunger.

Solution
Mechanical advantage = 8
But mechanical advantage = `"L"/"E"`
Here, L = 2 Kgf
Force applied at the handle of pump plunger = E =?
⇒ M.A. = `"L"/"E"`
8 = `2/"E"`
E = `2/8=1/4`
= 0.25 kgf.
