HFC2 Triangle of Forces Apparatus

HFC2 Triangle of Forces Apparatus

A bench mounted circular table with a central pin and 360º protractor has three pulleys on adjustable clamps round the edge. Conditions of equilibrium are obtained by centralising a small cord ring over the central pin with cords to load hangers where the loads and lines of action are variable.

The triangle of forces in equilibrium can be constructed and the resultant of two known forces can be found.

HFC2 Triangle of Forces Apparatus
  • Resolution of three static, co-planar forces; determination of triangle of forces and verification of closed triangle when in equilibrium; finding resultant force from 2 known forces.
  • The simple, bench mounted apparatus consists of a work surface, 3 variable position pulleys, a ring with 3 cords, 3 weight hangers.
  • The work surface features a central spigot and a central in-built protractor scale.
  • An instruction manual for student and lecturer provided.
  • Set of weights.
  • 2 year warranty
  • To find any suitable combination of three coplanar forces in equilibrium
  • To compare the results with the graphical solution obtained by drawing the triangle of forces
  • To demonstrate that the resultant of two known forces is equal and opposite to the equilibrant found experimentally
