WebRecall that the moment of a force about a point is given by 𝑀 = ± 𝐹 𝑑, where 𝐹 is the magnitude of the force and 𝑑 is the perpendicular distance between the force and the point about which the moment is taken. If the force produces a clockwise rotation, the moment is negative. section 2 of the care act 2014 https://road2running.com
