A lesson on using trigonometric ratios (sine, cosine, and tangent) to solve for a missing side length or angle measure in a right triangle.

A lesson on the basics of vectors and how to find horizontal and vertical components using trigonometry.

A lesson on adding vectors by summing their horizontal and vertical components. The resultant vector is then put in polar form (magnitude and direction).

A lesson on how to find external reaction forces using three equilibrium equations: The sum of the forces in the x direction, the sum of the forces in the y direction, and the sum of the moments about a point.

A lesson on solving a truss. Topics covered include determining whether the truss is statically determinate, finding external reaction forces, and finding internal forces.
