Sunita uses a lever of length 5m to lift a piece of stone weighting 1000N If the distance of load from fulcrum is 1m how much effect does she apply to lift the pieces of stone?

Answer 1

Answer:

it is according the principle of moments

required force will be 5000 N

Explanation:

F1 x L1 = F2 x L2             F1 = 1000 N  ,   L1 = 5 m  ,  L2 = 1 m ,   F2 ?

F2 =  F1 x L1 / L2

F2 = 1000 x 5 / 1

F2 = 5000 N
