Resultants and Force Components

LECTURE 01
Here the 3 characteristics of a force (magnitude, direction, and point of application) are introduced and explained. The use of vectors as mathematical tools to describe forces is shown. The geometric head-to-tail method (i.e. parallelogram rule) is shown as the graphical meaning of force vector addition. The algebraic technique of splitting forces into orthogonal components and combining like components is shown as a method to find resultant force components. The technique of finding the magnitude of a resultant vector using its components is demonstrated, as well as using resultant components to find a resultant direction angle. All of these principles are first explained fundamentally, then demonstrated in a realistic example problem involving a tractor and a 4-wheeler working together to extract a tree stump.
