Its resonant period makes it resistant to changes from perturbing forces, which is what makes it a good timekeeping device. The stiffness of the spring, its spring coefficient, κ {\displaystyle \kappa \,} in N·m/radian^2, along with the balance wheel's moment of inertia , I {\displaystyle I\,} in kg·m 2 , determines the wheel's oscillation ...
The effects of this process will remain for a period of time known as the "refractory period", during which the joint cannot be "re-cracked", which lasts about 20 minutes, while the gases are slowly reabsorbed into the synovial fluid. There is some evidence that ligament laxity may be associated with an increased tendency to cavitate. [14]
A balance wheel, or balance, is the timekeeping device used in mechanical watches and small clocks, analogous to the pendulum in a pendulum clock.It is a weighted wheel that rotates back and forth, being returned toward its center position by a spiral torsion spring, known as the balance spring or hairspring.
If you have a smartwatch or fitness tracker band that contains fluoroelastomer, Alan says there’s no need to panic. “But it is good to be aware of cumulative exposure,” she says.
Shock resistant is a common mark stamped on the back of wrist watches to indicate how well a watch copes with mechanical shocks. In a mechanical watch, it indicates that the delicate pivots that hold the balance wheel are mounted in a spring suspension system intended to protect them from damage if the watch is dropped.

Raj Matharu, 31, of Northridge, faces one count of possession with intent to distribute methamphetamine, according to the U.S. Attorney's Office.
A perfectly diffusive sound space is one in which the reverberation time is the same at any listening position. Most interior spaces are non-diffusive; the reverberation time is considerably different around the room. At low frequencies, they suffer from prominent resonances called room modes.
