Homework Help: Component forces on angle bracket

    1. The problem statement, all variables and given/known data
    See photo attachment

    2. Relevant equations

    3. The attempt at a solution
    Ive begun by defining an x and y axis, followed by find the sum of x-components of the forces, and y-components. Followed by the magnitude of the resultant force. The only method i could think of was to find the total result moment of the x-components and let that equal to F.d, where F is the x-component of the total reaction force, and then do the same for the y-component to find the where it intersects BC.

    Your working image is very hard to read. There's not so much calculation here that you couldn't type it out in the edit box.

    In any event, it looks like you have calculated the incorrect components for the 175 N force to start with. You've got to pay attention to where the acute angle is defined and not just blindly assume that the cosine of the angle gives you the x-component of the force.
