# Calculate the forces in members AB, BH, and GH of the structure shown

What is the method used to calculate the forces in members AB, BH, and GH of the structure shown?

The method used to calculate the forces in members AB, BH, and GH of the structure shown is truss analysis.

## Truss Analysis for Calculating Forces

**Truss analysis**is a method used in structural engineering to determine the internal forces in the members of a truss system. A truss is a structure made of straight members connected at joints, and the members are assumed to be idealized and capable of supporting either tension or compression but not bending. In the case of the structure shown with members AB, BH, and GH, truss analysis involves applying the principles of equilibrium to analyze the forces at each joint. The goal is to calculate the forces acting in each member of the truss.

**Method of Joints:**One common approach to truss analysis is the method of joints, where forces at each joint are analyzed individually. By breaking down the forces at each joint into their horizontal and vertical components, we can determine the forces in the members connected to that joint.

**Method of Sections:**Another approach to truss analysis is the method of sections, where a cut is made through the truss to isolate a specific section. By analyzing the forces acting on the section as a whole, we can find the forces in the members that were cut. In the case of calculating the forces in members AB, BH, and GH of the structure shown, we can apply truss analysis using either the method of joints or the method of sections. By considering the equilibrium of forces and analyzing the connections at the joints, we can determine the tension or compression forces in each member.
