That is not the correct answer for Ay and By. That is the correct answer for Ax and Bx (you correctly solved for Ax in your 2nd post). Note: It is assumed that x is the horizontal axis and y is the vertical axis.NoobeAtPhysics said:
A truss is a structure made up of interconnected bars or beams that are designed to withstand tension and compression forces. It is commonly used in construction to support roofs, bridges, and other structures.
To solve a simple truss problem, you must first draw a free body diagram of the truss. Then, apply the equations of equilibrium to determine the unknown reactions at the support points. Finally, use the method of joints or method of sections to find the internal forces in the truss members.
The reaction force at point A is the force exerted by the support on the truss at that point. It is typically a vertical or horizontal force that is equal in magnitude and opposite in direction to the external loads applied to the truss.
The types of support in a truss include pinned, roller, and fixed support. A pinned support allows rotation but not translation, a roller support allows translation but not rotation, and a fixed support does not allow either rotation or translation.
To check if your solution is correct, you can perform a static analysis by ensuring that the sum of forces and moments in the x and y directions is equal to zero. You can also check if your solution satisfies the equations of equilibrium and is consistent with the given external loads and support conditions.
