Question

A load of 1000 N can be lifted by applying an effort of 250 N. If the load arm is 25 cm, calculate the effort arm. Please show me step wise step. I will mark you as the brainliest.

Answer 1

Answer:

Explanation:Solution :

Since the fulcrum lies in between the load and effort, it is class I lever.

Mechanical advantage (M.A.) of levers is given by,

M.A.=effort armload arm=50cm10cm

Thus, mechanical advantage , M.A. = 5.

Given, effort (E)=10N, Load(L)=?

∴L=E×M.A.

=10×5=50N
