The method of joints is strongly analogous to node-voltage analysis in electronics; you can sort of think of the forces as "currents", and the joints as "nodes".

@jacobandrewdorler 3 жыл бұрын

Very helpful in breaking down the method. I went and watched the Solids: Lesson 2 traffic light video to better understand the portion during Joint B where he's naming the component vectors (4/5BD; 3/5BD vs. BDcos(53.13); BDsin(53.13). Great for architects studying for their PDD Exam! Thank you!

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.
