. The mobile crane is symmetrically supported by two

Chapter 5, Problem 5-26

(choose chapter or problem)

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. If the crane boom and truck have a mass of 18 Mg and center of mass at \(G_{1}\), and the boom has a mass of 1.8 Mg and a center of mass at \(G_{2}\), determine the vertical reactions at each of the four outriggers as a function of the boom angle \(\theta\) when the boom is supporting a load having a mass of 1.2 Mg. Plot the results measured from \(\theta=0^{\circ}\) to the critical angle where tipping starts to occur.
