Question

if the MA of machine is given 15 and the load arm is given 4 cm calculate effort arm​

Answer 1

Answer:

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
