A force of 50 N acts on the right shoulder of the lever, its length is 10 cm What exactly is the left shoulder if a force of 10 N acts on it.
Given: Fп (the force that acts on the right arm of the lever) = 50 N; lp (length of the right arm of the lever) = 10 cm (0.1 m); Fl (force acting on the left shoulder) = 10 N.
Solution: If we assume that the lever in question is in equilibrium, then the length of the left arm of the lever can be determined from the equality: Fp * lp = M = Fl * ll, whence ll = Fp * lp / Fl = 50 * 0.1 / 10 = 0 , 5 m.
Answer: The left arm of the lever is 0.5 m.
