Lesson 3 on Non-Concurrent Forces:: Find the Resultant and Where It Acts by Drawing

In Lesson 3 the forces are spread out across a plate and their lines of action do not meet at one point. Using the graphical method, you will find the size, the direction and the position of the resultant, step by step: the force diagram, the polar diagram and the link polygon, with Bow's notation.
