31-40. The weight W of a traveling crane is 20 tons acting as shown in the figure. To prevent the cran from tipping to the right when carrying a load P of 20 tons, a counterweight Q is used. Determine the valu and position of Q so that the crane will remain in equilibrium both when the maximum load P is applie and when the load P is removed. 20 tons P= 20 tons
