  • Moments are measured in Newton-meters (Nm).
  • The moment of a force is defined as the product of Force and perpendicular distance between the force and pivot
  • A force can accelerate or change the velocity or direction of a moving body
  • If a point in the body is fixed the force applied can cause the body to rotate either clockwise or anticlockwise
  • A force to the right and acts downwards causes a body to rotate clockwise
  • A force to the right and acts upwards causes a body to rotate anotclockwise
  • A force to the left and acts upwards causes a body to rotate clockwise
  • A force to the left and acts downwards causes a body to rotate anotclockwise
  • Moment of a force is equal to force by perpendicular distance
  • The moment of a force can be used to determine if a body is in equilibrium
  • Equilibrium refers to when a body is in rest or stationary state.
    Total upward force=Total downward force
  • Equilibrium refers to when a body is in rest or stationary state.
    Total upward force=Total downward force
  • Principle of moments:"For a body in equilibrium the sum of the clockwise moments at a point is equal to the sum of the anticlockwise moments at the same point"
