force – gondola car suspended between 2 cables

1. The problem statement, all variables and given/known data

A gondola car with mass 137 kg is suspended between two cables which sag at an angle of 37° below horizontal, on either side. What is the tension in each cable?

3. The attempt at a solution

2Tsinθ = mg => T = mg/2sinθ
= (137 kg)(9.8 m/s2)/2sin37°
= 1115 N
