Homework Help: General Question about Moment

  1. Oct 16, 2007 #1
    When taking the moment in 3 space i know the formula is

    M = r x F

    but for example ifyour finding the moment of force F about point C

    how do u know from point C to where you have to make the line.

    like if u have

    ------------------> about point C


    you can make it

    ------------------> F


    Ive read that the ca is a vector from point C to ANYWHERE on the line of action. So does that mean any where from point C to the line F ANYWHERE???
