Forces, moduli F1 = 15 N and F2 = 30 N, are balanced on the lever. Moreover, their moments are equal to 60 N * m.

Forces, moduli F1 = 15 N and F2 = 30 N, are balanced on the lever. Moreover, their moments are equal to 60 N * m. What are the shoulders of these forces?

M = Fe
M1 = M2 = 60n * m
M1 = F1 * E1
M2 = F2 * e2
60 = 15 * e1
e1 = 60/15 = 4 meters
60 = 30 * e2
e2 = 60/30 = 2 meters
Answer: the length of the shoulder that is pressed with a force of 15n is 4 meters, which is 2 meters with a force of 30n.
