The steel I-beam in the drawing has a weight of 1.53 × 103 N and is being lifted at a constant velocity. What is the tension in each cable attached to its ends?

Answer 1

The angles = 70o?.

T1*sin70 + T2*sin70 = 1530 N.
T1 = T2.
2T1*sin70 = 1530.
T1 = 814 N. = T2.

Answer 2

I agree with that guy
