The lever is acted upon by a force of 8 N. What is the moment of this force if the shoulder of the force is 20 cm?

Given:

F = 8 Newton – force acting on the lever arm;

l = 20 centimeters – the length of the lever arm.

It is required to determine the moment of force P (N * m).

Let’s convert centimeters to meters:

l = 20 centimeters = 20 * 0.01 = 0.2 meters.

Then the moment of force will be equal to:

P = F * l = 8 * 0.2 = 1.6 Newton * meter.

Answer: the moment of force is 1.6 Newton * meter.
