Discussion :: Equilibrium of a Rigid Body - General Questions (Q.No.5)


The flying boom B is used with a crane to position construction materials in coves and underhangs. The horizontal "balance" of the boom is controlled by a 250-kg block D, which has a center of gravity at G and moves by internal sensing devices along the bottom flange F of the beam. Determine the position x of the block when the boom is used to lift the stone S, which has a mass of 60 kg. The boom is uniform and has a mass of 80 kg.

[A]. x = 2.500 m
[B]. x = 0.340 m
[C]. x = 1.180 m
[D]. x = 0.600 m
