Problem $12\mathrm{.}020-$ A flat$-$bed trailer

The flat$-$bed trailer carries two $1,550-$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 $0\mathrm{.}25$ and $0\mathrm{.}30,$ respectively. Assume

that the load does not shift.

Problem $12\mathrm{.}020.$a $-$ Acceleration of the trailer and its corresponding tension in the cable

Determine the maximum acceleration of the trailer and the corresponding tension in the cable.

The maximum acceleration of the trailer is

$\frac{m}{s^2}.$

The corresponding tension in the cable is

kN $.$
