Question
The figure shows a horizontal beam of mass M = 22 kg and length L = 3.9 m supported at its left
end by a frictionless pin and at the other end by an ideal cable attached to wall h = 1.6 m above the
beam. A mass m = 9.7 kg is suspended from the beam a distance d = 1.6 m from the wall. Find the
magnitude R of the "reaction force" exerted by the pin on the beam.
