Two objects, Object 1 and Object 2, are balanced on a beam, as shown above. A triangular column is placed underneath the center of the 10 m long beam and provides a 60 N force to the beam. Object 1 has an unknown mass, m,and is 4.5 m from the column. Object 2 has a mass of 3 kg and is 1.5 m from the column. The image above is not drawn to scale. Object 2 is now removed so that the system is no longer in equilibrium. Model the beam to be a rod rotating about the center (l=1l12m|"2). Determine the linear acceleration of the beam as it rotates towards the floor. .1, Add file
