Adding Forces Example 1

The video tutorial explains how to add forces together using an example. It begins by introducing the problem of finding the resultant force of three forces acting on a structure. The tutorial then demonstrates how to deconstruct each force vector into horizontal and vertical components, considering the direction of each force. Calculations are shown for each force, and the resultant force vector is determined by summing the components. The final analysis reveals that the resultant force is purely downward, replacing the original forces.
