Question

An object is suspended from the ceiling with two wires that make an angle of 40° with the ceiling. The weight of the body is 150 N. What is the tension in each wire?

41.6 newtons
82.3 newtons
150 newtons
117 newtons

Answer 1

Refer to the diagram shown below.

Let T =  the tension in each wire.
For equilibrium,
2T cos(50°) = 150 N
1.2856T = 150
T = 116.677 N ≈ 117 N

Answer: 117 N
