The counterweight C weighs 31,000N; the motor M weighs 4500 N; the weight of the boom ABis 36,000 N and can be considered as acting at point G; andthe weight of the tower is 23,000N and can be consideredas acting at its midpoint.is used to liftIt is desired that the reaction forces at the feet D and Ealways be greater than 4500 N to ensure that the toweris never in danger of tipping over. Plot Wmax, the max-imum load that can be lifted as a function of the dis-tance x (0
