Moment and cross product

  1. Oct 12, 2011 #1
    F = 5i + 3j Newtons acts 3 m to the right of the origin (x is horizontal and y is vertical). What moment does this force produce about the origin? Use the vector cross product.

    Who says you have only one vector? Remember, a vector has magnitude and direction.

    Does this help?

    [itex]\bar{M}_{o} = \bar{R}[/itex] X [itex]\bar{F}[/itex]
