Question

A load W = 666 Kilonewtons is supported by two steel cables one of which makes an angle of 35o with the horizontal while the other makes an angle of 75o with the horizontal.

What is the Force or tension in NEWTONS of the 75o cable

Answer 1

$$-T_1\cos75°+T_2\cos35°=0,\\ -W+T_1\sin75°+T_2\sin35°=0,\\\space\\ T_1=580568\text{ N},\\ T_2=183436\text{ N}.$$
