How do I solve for this question

2. The stationary wheel loader is lifting the load at B vertically with acceleration ap. If the weight of the load B is 10000 lb, the weight of the wheel loader is 33000 lb, I=118 in, h = 90 in, and d = 27 in, determine the largest value of an 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. (10 points) CAT do B d
