Question
(c) Shown in Figure 5, the drop gate at the end of the truck has a mass of 0.5 Mg at point
G. It is supported by cable AB and hinge C. Calculate the tension of the cable AB when
the truck accelerates at 4.7 m/s?. If the size of the drop gate is extended by 30%, the
center of gravity of the drop gate to hinge C become 1.56 m and the mass becomes 0.65
Mg. If the acceleration is the same, redesign the support system so that the tension of
the cable is the same. Find the reaction of hinge C for the new.
