F = 4 Newton – the force that acts on the lever arm;
x = 5 centimeters is the shoulder length of this force.
It is required to determine p (N * m) – the moment of force F.
We translate the units of measurement of length into the SI system:
x = 5 cm = 5 * 10-2 = 5/100 = 0.05 meters.
Then, to determine the moment of force, you must use the following formula:
p = F * x = 4 * 0.05 = 0.2 N * m (Newton per meter).
Answer: the moment of force F is 0.2 N * m.
