A loading car is at rest on a track forming an angle of $25$ with the

vertical. The gross weight of the car and its load is $5500$ lb$,$ and it acts at

point G$.$ Knowing the tension in the cable connected at C is $3000$ lb$,$

determine the $($a$)$ the acceleration of the car, $($b$)$ the reaction at each pair

of wheels. $[$Answer: $11\mathrm{.}62$ ft$/$s$2,1522$ lb$,802$ lb$]$
