## Homework Equations

sigma m = F *D

## The Attempt at a Solution

I had this question on a test today and am very curious to know the answer.

if someone strong in physics please solve it.

I got 51 something Kilo Newton for the reaction at A.

For the tension i got 46.08 Kilo Newton i believe.

thank you.

EDIT: In my reaction/moment calculation I included the force of the cable. that being said i forgot to account for the y direction of the cable. should the cable have been accounted for?
