Question

The blocks B and C in the figure have mass m each. The strings AB and BC are light, having tensions T₁ and T₂ respectively. The system is in equilibrium with a constant horizontal force mg acting on C.

(a) tan θ₁ = 1/2

 (b) tan θ₂ = 1

(c) T₁ = √5mg

(d) T₂ = √2mg

Answer 1

Correct Answer is: (a, b, c, & d)

Draw the free-body diagrams for B and C. Balance horizontal and vertical forces separately for both.
