    I've never seen an online tutorial for a difficult class laid out so plainly and easy to understand. There were no equations left out that I was expected to just know. I felt like I was kept in the loop of his thinking the ENTIRE time which is exactly what I need when I learn. So thank you Jeff. Absolute life saver

    Thanks so much. This really helped me understand where I was messing up with carrying the negative signs. I now understand that when you go to another joint you carry the magnitude but the positive or negative x,y component is relative to the x,y coordinate of the joint. So if a force is positive on one joint it could be negative on the same line of action at another joint.

    There is a mistake at the end when we are looking at joint C. Please help
    In the Y direction we have Fy = 0 = 11 (reaction force) - CDxSin45 = 11 - 0,7CD
    Therefore CD = 15.56
    However Sin 45 = Cos 45 = 0.7
    So in X direction we have Fx = 10 (BC) - CDxCos45 = 10 - 0,7 CD
    Which means CD = 14.28
    There must be a mistake somewhere because if the angle is 45, which it is, BC and the 11kN reaction force must be equal.
    Can someone help me figure it out.
