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

    http://img860.imageshack.us/img860/6320/tthing.jpg [Broken]

    In the drawing is described a beam structure fixed at point C, and held by a cable BD to the floor. The beam is loaded by two concentrated forces, F1 and F2, as described in the drawing.

    Given

    F1 = 700 [N]
    F2 = 400 [N]

    If it's known that the cable tension equals 1250 [N], calculate:

    A) The reaction force at C
    B) The fixation moment Mc at point C.

    Ignore weight of cable and structure. Measurements are in mm.

    3. The attempt at a solution

    Manual says

    Cx = 80.77

    I think your answer would fit if you subtract 50 N from F2.

    Would that work for you too? :wink:
