Determine the location ( x ¯, y ¯) of the center of gravity of the three-wheeler

Question

Determine the location (x¯, y¯) of the center of gravity of the three-wheeler. The rear wheels have a weight of 19 lb and a center of gravity at 1, the mechanical components have a weight of 80 lb and a center of gravity at 2, the frame has a weight of 125 lb and a center of gravity at 3 and the front wheel has a weight of 9 lb and a center of gravity at 4. If the three-wheeler is symmetrical with respect to the x-y plane, determine the normal reaction each of its wheels exerts on the ground. (Figure 1)
