Spring Sets
Equal Length Spring Set
ME-8970
P Equal length (30 cm)
P Color coded by spring
constant
P Set of five springs
P 25 N/m to 50 N/m
These springs appear to be the
same except for their color.
But, when equal masses are
hung on them, each stretches a
different amount. The extension
springs are made of steel and
are closed, requiring a slight
initial force to separate the
coils. The unstretched length of
each spring is 30 cm and the
approximate diameter is 1.4
cm. Springs come with a white
storage box with cardboard
separators to keep the springs
from touching each other.
The five color-coded springs stretch different
amounts when a 1 kg mass is hung from each
spring.

Equal Length Spring Set ....................................................ME-8970
Shown in use with:
Hooked Mass Set ....................................................................SE-8759 p. 107
Clamps and Rods ................................................................................................. p. 108
Series/Parallel Spring Set
ME-6842
P Equal length (15 cm)
P Color coded by spring constant
P Six springs, three spring constants
P 10 N/m, 20 N/m, 40 N/m
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 (ME-8970), making
it possible to combine
two series short springs
in parallel with one long
spring.
Shown in use with the
ME-6844 Parallel Spring
Bracket and the SE-8759
Hooked Mass Set
(see page 105).

Multi-Length Spring Set
ME-6848
P Equal spring constant
Parallel Spring Bracket
ME-6844
This unique bracket allows springs of different spring constants to
be hung in series and parallel. The masses can be hung in an offset
position to compensate for the stronger spring.
Parallel Spring Bracket is shown at right
in use with the ME-6842 Series/Parallel
Spring Set, the ME-8970 Equal Length
Spring Set, and the SE-8759 Hooked
Mass Set.
The four springs in this set appear to have
the same diameter and wire material,
but are actually designed to have the
same spring constant even though they
have different lengths. It makes a perfect
companion to the ME-8970 Equal Length
Spring Set and the ME-6842 Series/Parallel
Spring Set.
Springs have an approximate diameter
of 1.5 cm with a spring constant of 40 N/m.
Lengths are 13 cm, 19 cm, 24 cm, and
29 cm.
Order Information:
Multi-Length Spring Set ..............ME-6848
Includes
Suspension bracket
Parallel hook bar
Set-up at left includes the use of the
ME-9866 Demonstration Spring Set. Note the
cm markings (see inset) on the Parallel Hook Bar.
By calculating the applied torques, the relative
forces from the two springs can be investigated.
