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.

What is the significance of the positive and negative signs in the components of the forces?

What are the horizontal and vertical components of force F1?

How do you calculate the resultant force vector from the individual forces F1, F2, and F3?

Describe the final resultant force vector in terms of its direction and magnitude.

Explain how the forces can be replaced with the resultant force vector in the context of the structure.
