## Equilibrium of bodies connected by cord and pulley – application of Newton’s first law problems and solutions

1. A box of mass 5 kg is on an inclined plane at an angle 30o. The box supported by a cord. Determine the tension force (T) and the normal force (N)! Solution ∑Fx = 0 T – w sin 30o = 0 T = w sin 30o T = (5 kg)(9.8 m/s2) sin 30o …
