Investigating bodies in rotational and translational equilibrium. Uses specialised equipment allowing the balancing of up to 5 forces in different directions at once.


  • Determine the resultant of a number of vectors from diagrams drawn to scale.
  • Determine the resultant force by resolving the forces into orthogonal components.
  • Investigate torque.
