The tower crane is used to hoist a 2.2-Mg load upward at constant velocity. The 1.5-Mg jib BD and 0.4-Mg jib BC have centers of mass at G1 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 located at G3.
