Description and Specification for Lab Tenders
Astra Scientific Link Polygen Apparatus.
For use with the Work Panel, the kit allows several experiments with forces pulling on one or more points at different angles.
Students or teachers fit the magnetic parts of the kit to the Work Panel
to study or demonstrate three coplanar concurrent forces (triangle of
forces) or more (force polygons).
The kit uses masses, hooks, pulleys and cords to apply forces on a
single point (concurrent). Students may also set it to apply forces to
two points (non-concurrent). Students measure the forces at equilibrium
and compare with theoretical values. The kit introduces ‘Bow’s Notation’
and the drawing method of finding the forces.
The versatility of the kit means that you can set up to five forces at
any angles, using its cords, rings, magnetic mounts, magnetic
protractors, pulleys, weights and a spring balance.
