Activity 2.1.7 Calculating Truss Forces
Introduction
Because of the rigidity of a truss shape, it is not difficult to find the familiar triangles in many structures. Designers must accurately determine how much force occurs at locations of a truss design. The designer may change the material, the amount of material, or the number of members in a truss in order to make a design safer or more efficient. The calculations for determining truss forces are also a good basis for calculating forces for many other systems.

Conclusion
1. What is the significance of including roller connections rather than pinned connections?
Roller Connections only provide 1 axis of resistance to a Truss which can be the difference between making a truss calculable or incalculable. Roller Supports also allow a Truss to move around.
2. How does the triangle shape make a truss rigid?
The triangle shape of a Truss makes it rigid because it puts little peaks in the truss and between the triangles of the truss, there are small gaps.
