How hard does the beam push inward on the wall?
The Attempt at a Solution
I know that the tension on the cable is 1.32*10^4 N
From there I turned the weight and tension into x/y components and tried to add the x components, so that:
1.32*10^4cos(40) + 14700sin(30) = 17461.79 N
I don't understand why this is not correct?
