The portable hydraulic crane with mass mg = 60 kg is stationary as it lifts the crane .with mass mc = 110 kg vertically with acceleration ac. The mass center of the crate is at C and the mass center of the crane is at G. If d = 0.145 m, e = 1.3m and h = 0.27 m determine the maximum value of the acceleration ac, such that no wheel reaction exceeds 400 N. Assume that the crane is laterally symmetric so that the loads on the front wheels are equal and the loads on the rear wheels are equal
