Re: [Phys-l] Euler Buckling springs



Thank you!

A significant problem in precision clock pendula is support movement. The usual partial solution is to bolt the support to a brick (figurative and sometimes actual) wall. Here in earthquake country this is counter productive.

A number of horologist report on their unintended detection of earth quakes. e.g.

bc notes the concrete slab isolation of a vacuum environment pendulum.

Damping vibrations is just mechanics - or is it - when the application
is LIGO?
In the same vein, here's some material on buckling springs for vibration
dampers
(as submitted to Classical and Quantum Gravity 2001.)

It's an unusually lucid and accessible narrative on avoiding unwanted
body resonances.
