The flat-bed trailer carries two 2000-kg beams with the upper beam secured by a cable. The coefficients of static friction between the two beams and between the lower beam and the bed of the trailer are 0.25 and 0.30, respectively. Knowing that the load does not shift, determine
1. The maximum acceleration of the trailer and the corresponding tension in the cable
2. The maximum deceleration of the trailer.
