The crane is supported on the ground at points A and B. The crane has a mass of 18000 kg and it acts at the point G1. Crane is lifting a load of 2500 kg, hanging at the right end of the boom. Neglect the weight of the boom. As the angle theta of the boom, increases from 0 to 90 degrees, plot the normal reactions at points A and B as the function of theta. At what angle will the crane start to tip?
