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
C
you can make it
------------------> F
-a
-
C
or
------------------>F
-a
-
-
C
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???
