A 15-ft beam weighing 500 lb is lowered by means of two
Chapter 16, Problem 16.60(choose chapter or problem)
A 15-ft beam weighing 500 lb is lowered by means of two cables unwinding from overhead cranes. As the beam approaches the ground, the crane operators apply brakes to slow the unwinding motion. Knowing that the deceleration of cable A is \(20\mathrm{\ ft}/\mathrm{s}^2\) and the deceleration of cable B is \(2\mathrm{\ ft}/\mathrm{s}^2\), determine the tension in each cable.
