Question

The weight distribution in a mobile crane is modeled as being three distinct weights, WG1 = 3.4 [kN], WG2 = 2.6 [kN], and WG3 = 2.8 [kN] with application points at the three centers of gravity G1, G2, and G3 as shown in the figure. Given the geometry $w_1$ = 1.8 [m], $w_2$ = 1.5 [m], $w_3$ = 1.2 [m], $w_4$ = 1.5 [m], and $w_5$ = 1.8 [m], find the following: Part 1. Find the maximum weight the crane can lift before it tips forward. Part 2. Find the magnitude of the normal force acting on the tire at A when the crane lifts this maximum weight (just before it tips forward). Part 3. Find the magnitude of the normal force acting on the wheel at B when the crane lifts this maximum weight (just before it tips forward).
