1. The problem statement, all variables and given/known data How hard does the beam push inward on the wall? 2. Relevant equations 3. 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?
