The mobile crane is symmetrically supported by two outriggers at A and two at B in order to relieve the suspension of the truck upon which it rests and to provide greater stability as shown in . Suppose that the crane and truck have a mass of 18 Mg and center of mass at G1, the boom has a mass of 1.8 Mg anc center of mass at G2. The boom is supporting a load having a mass of 1.4 Mg. Determine the positive critical angle 0max (in degree) where tipping starts to OCcur.
