A common technique used to measure the
force constant k of a spring is the following:
Hang the spring vertically, then allow a
mass m to stretch it a distance d from the
equilibrium position under the action of the
“load” m g.
Find the spring constant k if the spring
is stretched a distance 16 m by a suspended
weight of 96 N. The acceleration of gravity is
9.8 m/s^2
Answer in units of N/m.
