1. Description
The force table serves to prove that force is a vector
quantity. It is also used for quantitative investiga-
tion of how forces combine and resolve.
The force table consists of a circular work disc on a
stable base with a dual angle scale. Weights are
attached to three pulleys with securing clamps. The
three sets of brass weights consist of 2x 5 g, 2x 10 g,
2x 20 g and 2x 50 g weights and weight holders
weighing 50 g.
2. Technical data
Dimensions: 300 mm x 390 mm dia. approx.
Scale: 0 to 360° with 1° resolution
Weight: 3 kg approx.
3. Principle
Forces are vector quantities. This means that the
resultant of two forces working at a single point is
not simply the sum of the forces but is dependent
