the tower crane is used to hoist the 1.1-mg load upward at constant velocity. the 1.7-mg jib bd, 0.2-mg jib bc, and 6.4-mg counterweight c have centers of mass at g1, g2, and g3, respectively. determine the resultant moment in kn·m produced by the load and the weights of the tower crane jibs about point a. ( in kn.m and assume counterclock wise as positive, clockwise as negative)
