    • What is a moment?

      When a force is applied to an object it will produce a tendency for the body to rotate
    • What is the equation of the magnitude of a moment at a certain point?
      Force x perpendicular distance
    • How is the direction of a moment found?
      The direction of a moment is defined by its moment axis which is perpendicular to the plane that contains the force and the moment arm
    • What rule is used to find the direction of a moment?
      The right hand screw rule: thumb points in the direction of the moment axis, fingers point in the direction of the moment arm
      Anticlockwise/out of page = positive
      Clockwise/into page = negative
    • What is a couple?
      Two forces, equal in magnitude, parallel but opposite in direction
