Simple Truss Problem Q1 Reaction forces

The video tutorial explains how to calculate reaction forces in a simple truss structure. It begins with setting up the problem, including defining the truss and external forces. The instructor then creates a free body diagram, identifies the types of supports, and defines the axes and necessary formulas. The video proceeds to solve for reaction forces using algebraic methods and verifies the results through torque calculations. The tutorial concludes with a summary of the solutions and a brief introduction to upcoming topics.

What is the external force acting downwards on Point C of the Truss?
