Trusses and Member Forces

Aerospace structures often need to be strong without using solid, heavy blocks of material. Trusses create stiffness by arranging members in efficient geometric patterns.

A truss uses connected members, often triangles, to distribute loads through tension and compression. Load path, joint design, member length, and bracing all affect performance.

Analyze or build a simple truss and identify which members are likely in tension, compression, or low load.

Create a truss force path diagram with load arrows, supports, and labels for at least five members.

A good truss design is not only about shape. It is about how forces travel through the members and joints.
