Q2/ a) The tower crane is used to hoist a 2Mg load upward at constant velocity. The 1.5-Mg jib BD and 0.5Mg jib BC have centers of mass at Gl and G2, respectively. Determine the required mass of the counterweight C so that the resultant moment produced by the load and the weight of the tower crane jibs about point A is zero. The center of mass for the counterweight is 5m 125m 23 m located at G3?
