A uniform light beam XZ is Hinged at X and kept in equilibrium by the forces T and F as shown in the diagram above. if XO = 20cm and OY = 30cm, express T in terms of F

F × (20cm + 30cm) = T sin 30° × 20

50F = 10T

T = 50F/10
T = 5F.

Sum of upward forces= sum of downward forces
Tsin30° × 20 = F × (20 + 30)
since sin 30 = 0.5
10T = 50F
T = 5F
