Moments

• $M =$$Fd$

  • Moment of force (M) in newton-metres (Nm)
  • Force (F) in newtons (N)
  • Distance (d) in metres (m)
• If an object is balanced, the total clockwise moment about a pivot equals the total anticlockwise moment about that pivot
• A simple lever and a simple gear system can both be used to transmit the rotational effects of forces
