The force exerted by a spring is expressed as:

F=-kx

where F is the force, x is how far it's stretched and k is the spring rate, or spring constant.

The potential energy of a spring looks suspiciously like the standard Kinetic Energy formula:

PE=1/2kx^2

Instruments to measure barrel time are pressure/vibration strain gauges. More information about strain gauge instruments, barrel time and links to barrel harmonics and the like can be found here:
