4) F θ O r |F | sin θ ∼ O θ |r | If you curl the fingers of your right hand in the direction of rotation caused by a force your thumb points in the direction of the moment vector. θ ∼ The expression we have found for the right side of eqn. 4 is the 2D cross product of vectors r and F . We can now apply the concept to any pair of vectors whether or not they represent force and position. The 2D cross product is defined as : de f = ˆ |A| |B| sin θ k. 22: The moment of a force is either the product of its radius with its perpendicular component or of its lever arm and the full force.
In the x y plane, the 2D moment is a vector in the kˆ direction (straight out of the plane). So eqn. 3 becomes ˆ M/C = | r | |F | sin θ k. 4) F θ O r |F | sin θ ∼ O θ |r | If you curl the fingers of your right hand in the direction of rotation caused by a force your thumb points in the direction of the moment vector. θ ∼ The expression we have found for the right side of eqn. 4 is the 2D cross product of vectors r and F . We can now apply the concept to any pair of vectors whether or not they represent force and position.
