Suppose one truck is parked on a bridge as shown in Figure. The truck weighs 1000 lb which is acting through its center of gravity (CG). The bridge weighs 200 lbs per foot, which is uniformly distributed. We can assume the bridge is rigid. Determine the reaction forces at the supports of bridge at the two ends.
