1: The crane shown is symmetrically supported by two outriggers at A and two at B. If the crane and truck have a mass of 18 Mg and center of mass at G1, and the boom has a mass of 1.8 Mg and a center of mass at G2, determine the vertical reactions at each of the four outriggers as a function of the boom angle when the boom is supporting a load having a mass of 1.2 Mg. Plot the results measured from zero to the critical angle where tipping starts to occur.
