Homework Help: Forces in members

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

    As shown, a load of magnitude P is applied to a structure. Assuming that all members are weightless and that ABEF and BCD are rigid bodies, find the magnitudes of the reactions at D and G needed to maintain the structure in equilibrium.


    Assume the following values: a_c = 3.60 m, b_c = 2.40 m, and P = 106 N. Express your answers numerically in newtons to three significant figures separated by a comma.

    Fd, Fg = ?

    Any help would be greatly appreciated.

    2. Relevant equations

    3. The attempt at a solution

    It couldn't hurt to write the equations of static equilibrium after making a free body diagram of this structure.
