Abstract
–
The main purpose of this laboratory experiment is to calculate the spring constant for a
given spring and to determine the effective spring constant.
Students will utilize a spring
mass system to calculate displacement values from an equilibrium position.
Using the
equation for the elastic nature of a spring, F
s
=kx, where F
s
is the spring force, k is the
spring constant, and x is the displacement from the equilibrium position, the value for k
can be determined.
The value for k was determined to be 85.0 N/m.
Students will then
be able to determine the value of the effective spring constant for springs in a parallel
configuration, springs in a series configuration, and springs in a mixed configuration.
These values, based on the calculated spring constant, will be compared to the theoretical
values.
The percent error for the effective spring constant of the parallel configuration
was 18.1%, for the series configuration was 19.4 %, and for the mixed configuration was
4.34 %.
Possible errors include gross error, systematic error, and random error.

Equations
The following equations will be used in this laboratory experiment:
F
s
= kx
where F
s
= spring force (N), k = spring constant or force constant (N/m), and x =
displacement from the equilibrium position (m).
Slope = ∆Y / ∆X
where ∆Y = Y
2
– Y
1
, and ∆X = X
2
X
1
. This equation will be used to calculate the slope of
the graph of F
s
vs. x in order to calculate the spring constant, k.
