Select the correct statements regarding the addition of moments. (Select 3) Moments have directions, so a negative value implies it is along the opposite direction from the reference direction. All the moments need to have the same reference point/pivot in order to add together. Calculate each moment by multiplying each force with its distance to the reference point, and add all values together, regardless of their direction. You have to define the reference direction first, either clockwise or counter-clockwise.
