Question

show that T1=√3 mg
Point p is at equlibrium

Answer 1

Answer:

Explanation:

this question can be solved using lami's theorem:

Lami's theorem states that if three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two forces. Consider three forces A, B, C acting on a particle or rigid body making angles α, β and γ with each other.

here,

Mg/sin 150°=T₁ /sin 120°

Mg/0.5=T₁/√3/2

T₁=Mg√3
