In this lesson, we will learn how to find the moment of vector forces acting on a body about a point in 3D.

Students will be able to

express the moment of a force as a vector,
find the moment of a force (or system of forces) in 3D when given the magnitude and direction of the forces acting on the system and the 3D coordinates of the relevant points,
find the moment of a force (or system of forces) in 3D when given the forces acting on the system, expressed on a diagram.
