A 30.0 kg child sits on one end of a long uniform beam having a mass of 20.0 kg, and a 40.0 kg child sits on the other end. The beam balances when a fulcrum is placed below the beam a distance 1.50m from the 30.0kg child. How long is the beam if the center of mass is 0.150m away from the fulcrum and located on the same side of the fulcrum as the 30.0kg child?
