Question

Find the tension in the two wires that support the 100 N light fixture. Assume θ is 39°.

left wire:
right wire:

Answer 1

I cant decipher the exact figure. However, the wires hang at an angle, so the vertical and horizontal components of tension can be determined. The sum of the left and right vertical components must equal the weight of the light fixture, and the horizontal components of tension must equal zero (they are equal and opposite).
