Calculate the load placed 10 m from the fulcrum that can be balanced by an effort of 5 Newton applied at a distance of 4 m from the fulcrum in a lever.

Respuesta :

Answer:

Explanation:

The diagram representing the scenario is shown below

x represents the unknown load

Moment = force x distance

moment about the left arm = 10x

moment about the right arm = 5 x 4 = 20

According to the principle of moments, moment about the left arm = moment about the right arm

Thus,

10x = 20

x = 20/10

x = 2

The unknown load is 2 N
