Sum Of Forces In A Line
Purpose
To demonstrate that forces in one dimension add algebraically.
Equipment
System assembled as photographed on request, with a set of weights.
Setup Time

Description
This demonstration consists of two strings connected at the same end of a brass spring that is suspended from one side of the support frame. The strings run over pulleys attached to each side of the frame, and are then connected to weights. Different masses can be hung on the two sides, creating differing forces in each direction.Using the scale provided, the displacement of the spring can be measured, and the forces can be seen to add algebraically.
