The flat-bed trailer has weight W1 and center of gravity at GT. It is pin-connected to the cab at D. The cab has a weight W2 and center of gravity at GC. Determine the range of values x for the position of the load L of weight W3 so that no axle is subjected to a force greater than FMax. The load has a center of gravity at GL.

Given:

W1 = 7000 lb a = 4 ft

W2 = 6000 lb b = 6 ft

W3 = 2000 lb c = 3 ft

Fmax = 5500 lb d = 10 ft

e = 12 ft
