Mechanics: Finding forces given loading conditions

  1. Apr 1, 2013 #1
    1. The problem statement, all variables and given/known data

    Determine the forces acting on members A, B, & C

    The coordinates for pins 1 and 4 are:
    1: (-32",24")
    4: (-18",28")
    There is a 1000lb force down on the bottom of the bucket as shown in the diagram. There are also angles of 40°, 18°, and 78° as shown in the diagram attached.

    2. Relevant equations

    I know the forces and moments need to be summed to determine the forces acting on the three members (A, B, and C) but I can't figure out how to do it right.

    3. The attempt at a solution

    My attempt as solving this problem is attached as a pdf file.
