The load per foot of beam length varies as shown. For x = 18 ft, the unit load is 601 lb/ft. At x = 0, the load is increasing at the rate of 51 lb/ft per foot. Calculate the support reactions at A and B. The reactions are positive if upward, negative if downward. [Answer: RA = 2280 ft, RB = 4080 lb]
