Question

Static Equilibrium:

ALREADY SOLVED #1 (T=13.9 N) please help with #2

1. A uniform, horizontal beam of mas 2kg and length L is hinged at a wall and supported by a cable, also connected to the same wall and to the end of the beam. If the cable makes a 45 degree angle with the beam, what is the tension?

2. In the problem above, the cable is shortened so that the beam is no longer horizontal. What angle should the cable make with the beam so that the tension is half the previous answer?
