The tower crane is used to hoist the 2 Mg load upward at constant velocity. The 1.5 Mg jib BD, 0. 5 Mg jib BC, and 6 Mg counterweight C have centers of mass at G1, G2, and G3, respectively. Determine the resultant moment produced by the load and the weights of the tower crane jibs about point A and about point B.
