The stationary wheel loader is lifting the load at B vertically with acceleration ao. If the weight of the load B is 10,000 lb, the weight of the wheel loader

is 33,000 lb, l = 118 in.,h = 90 in., and d = 27 in., determine the largest value of ao for which the reaction on each of the rear wheels does not drop below 1000 lb. The center of mass of the wheel loader is at A.
