You've got it right. From your equation, you can solve for Cy. Then use sum of forces in x direction = 0, and sum of forces in y direction = 0, to solve for Ax and Ay. Note that Cx must be zero, since it is a roller support that is free to slide in the x direction, and thus, can support no load in that direction.jellybellybea said:Homework Statement

I am generally lost, this isn't homework its practice for the final exam. Could someone help?
A truss is a structure made up of triangular units connected by straight members. It is important in solving loads because it can efficiently distribute and support applied loads, making it a common structural element in buildings and bridges.
The moment in a truss can be calculated by summing the moments of all the forces acting on a joint, using the principle of moments. This can be done using equations of equilibrium or by using a method called the method of joints.
Truss reactions are the forces that the supports exert on the truss structure. These reactions are essential in keeping the truss in equilibrium and ensuring its stability. If the reactions are not properly calculated, the truss may fail under applied loads.
The force in each member of a truss can be determined by using the method of joints or the method of sections. Both methods involve analyzing the forces acting on the truss structure and solving for the unknown forces using the equations of equilibrium.
Some common mistakes to avoid when solving truss loads include not considering the effects of distributed loads, not properly labeling forces and angles, and not ensuring that all the equations of equilibrium are satisfied. It is also important to double check calculations and use proper units to avoid errors.
