Series/Parallel Springs
Combine this set of six short springs with the Equal Length Spring Set (ME-8970) to observe spring behavior in series and in parallel.
The set of six springs consists of two each of three different spring constants. These springs are 15 cm long, half the length of the Equal-Length Spring Set, making it possible to combine two series short springs in parallel with one long spring.
