In the experimental setup shown in the Figure 1, a beam, B1 of unknown mass M1 and
length L1 = 1.00 m is pivoted about its lowest point at P1. A second beam, B2 of mass
M2 = 0.200 kg and length L2 = 0.200 m is suspended (pivoted) from B1 at a point P2,
which is a horizontal distance d = 0.550 m from P1. To keep the system at equilibrium,
a mass m = 0.500 kg has to be suspended from a massless string that runs horizontally
from P3, at the top of beam B1, and passes over a frictionless pulley. The string runs at
a vertical distance y = 0.707 m above the pivot point P1.
