A uniform beam 3.0 m long and mass 30 kg is hinged to a vertical wall at its left end. The beam is horizontal. A cable is attached to the beam 2.0 m from the hinge and makes an angle \(\theta\) above the beam. The cable is in tension and the beam carries its own weight acting at its centre. The hinge reaction is required to act at an angle of \(30^{\circ}\) above the horizontal. Determine the angle \(\theta\) (to the nearest degree) and the tension in the cable (to the nearest newton).

Answer Options

Correct Answer A. θ = 60°, T = 255 N (approximately)
B. θ = 60°, T = 180 N (approximately)
C. θ = 45°, T = 300 N (approximately)
D. θ = 75°, T = 210 N (approximately)
Correct Answer
A
Correct Option:
θ = 60°, T = 255 N (approximately)
