1R10.15 - The Suspended Slinky

Code Number:
Demo Title:
The Suspended Slinky
Stress & Tension
Area of Study:
Slinky, Suspending Clamp.

Suspend the slinky vertically from the attached clamp.  Note that the upper coils of the spring are spaced farther apart than the lower coils due to the mass of the spring and the small tension between adjacent coils.
