Are the forces at A the same for members ADE and member ABC?
Likewise, are the forces at D the same for members FDB and ADE?
Not sure what you're asking. There are forces at A due to members ADE and ABC, but those two forces will be different.princejan7 said:Are the forces at A the same for members ADE and member ABC?

Support reactions are the forces that occur at the point of contact between a structural element and its support, such as a beam resting on a wall or a bridge on its piers. These reactions are necessary to keep the structure in equilibrium and prevent it from collapsing.
To calculate support reactions, you need to analyze the forces acting on the structure using the principles of statics. This involves drawing a free-body diagram and applying equations of equilibrium to find the unknown reactions at the supports. The type of support (fixed, pinned, or roller) and the type of load (point, distributed, or concentrated) will also affect the method of calculation.
Support reactions are important because they determine the internal forces and stresses within a structure. They also ensure that the structure remains stable and does not experience excessive deflection or collapse. Understanding support reactions is crucial in the design and analysis of any structure.
The magnitude and direction of support reactions can be affected by various factors, such as the type and location of the supports, the type and magnitude of the load, and the geometry and material properties of the structure. Any changes in these factors can alter the support reactions and must be considered in the analysis.
Support reactions play a significant role in the design of a structure as they determine the size and shape of structural elements. Engineers must ensure that the support reactions do not exceed the capacity of the supports or cause excessive stresses in the structure. In some cases, additional supports may be needed to distribute the load and reduce the support reactions.
