2.1 7 Calculating Truss Forces Answer Key Pdf
Trusses are an important structural element in construction, commonly used in roofs, bridges, and towers. A truss is a framework comprising a series of interconnected triangles that distribute weight evenly across the entire structure. To calculate the forces acting on a truss, you will need a few formulas and equations.
What is a Truss?
A truss is a structure made of triangles that support weight and distribute it evenly across the structure. Trusses are often used in construction because they are strong, lightweight, and can span large distances. They are commonly used in bridges, roofs, and towers.
Types of Trusses
There are several types of trusses, each with their own unique design and applications. These include:
- King Post Truss
- Queen Post Truss
- Howe Truss
- Pratt Truss
- Warren Truss
- Scissors Truss
Calculating Truss Forces
Calculating the forces acting on a truss involves solving equations based on the geometry of the truss and the forces acting on it. These equations are used to determine the forces in each member of the truss, including the tension and compression forces.
Method of Joints
The method of joints is a straightforward way of determining the forces in a truss. In this method, you analyze the forces acting on each joint in the truss, one at a time. To do this, you first identify all the forces acting on the joint and draw a free-body diagram. Then, you use the equations of static equilibrium to solve for the unknown forces.
Method of Sections
The method of sections involves cutting through the truss to isolate a section and analyzing the forces acting on that section. This method is useful for determining the forces in members that are difficult to isolate using the method of joints.
