For example , this could be a door opening around a fixed or a turning around a fixed nut . The size of a moment depends on factors : the size of the applied the distance from the pivot to the line of action of the This explains why force is needed to open a door by pushing at the side from the hinge than at the side to the hinge . To push at the hinge side of the door requires force to be exerted because the distance is . A can be calculated using this equation : M = × where : M = the moment of the force in newton - metres , F = the force in newtons , d = the perpendicular distance from the line of action of the force to the pivot in , m
