Hooke’s Law Set

Introduction
PASCO’s ME-9827 Hooke's Law Apparatus allows students to
investigate the relationship between the force applied to a spring and
the amount the spring stretches. Its rugged base and brilliant stretch
indicator will provide years of use in the physics classroom. In
addition, it includes three different springs of varying stiffness. Each
spring has identical length and diameter, but the spring constant varies
between 4 N/m and 96 N/m. Three of each spring type are included for
a total of nine springs.
Equipment Assembly
The stand comes fully assembled, including the transparent scale. To
ready the unit for use, perform the following:
1.
Hang the desired spring
from the notch on the
support arm. (Figure 1).
2.
Connect the Stretch
Indicator to the bottom of
the spring.
3.
Align zero on the sliding
transparent scale with the
Stretch Indicator (Figure 1).
4.
Connect a mass hanger
to the bottom of the
Stretch Indicator. To
connect the mass hanger,
unclip the bottom wire
clamp and slide the
clamp through the slit on
the hanger (Figure 2).
The complete setup is
shown on the next page.

Note:
You may need to
adjust the clamp on the
support rod until the
indicator reading falls
at exactly zero. Always
take your reading from
the bottom edge of the
indicator.
