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.

Answer 1

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.
