$*6-108.$ The skid$-$steer loader has a mass of $1\mathrm{.}18$ Mg $,$ and in the position shown the center of mass is at $G_1.$ If there is a $300-kg$ stone in the bucket, with center of mass at $G_2,$ determine the reactions of each pair of wheels A and $B$ on the ground and the force in the hydraulic cylinder $CD$ and at the pin $E.$ There is a similar linkage on each side of the loader.

Prob. $6-108$
