Question 7

How do you find the unit for moment, force and distance in a MFD formula?

Answer 7

Moment - Combine the unit for force and the unit for distance (e.g. Newtons (N) + Metres (m) = Newton Metres (Nm)
Force - The left part of the unit for moment.
Distance - The right part of the unit for moment
