Sorry, no etymologies found.
The sunspot cycle is thought to arise from large-scale motions inside the sun: north-south and east-west flows (meridional circulation and torsional oscillation, respectively) and differential rotation in which the solar equator rotates faster than the poles.
Using data from the Global Oscillation Network Group (GONG) facility of the National Solar Observatory and from the Stanford University Michelson Doppler Imager (MDI) on NASA's Solar and Heliospheric Observatory (SOHO) spacecraft, we have constructed a map of the torsional-oscillation flow inside the sun over the past 14 years.
The torsional angles, which can be independently varied between 0° and 360°, are just two of the hundreds of configurable variables.
We created the torsional stiffness test with Microbac Laboratories, Inc,. to replicate and measure the effects of pedaling load on a bike.
Each bike was ridden for at least 30 hours, and then subjected to torsional stiffness testing in Colorado and aerodynamic drag testing in North Carolina.
How much do they vary in torsional stiffness – and how does that affect the ride quality?
An explanation of the torsional stiffness test we co-developed with Microbac Laboratories can be found here.
Thickly padded, laterally stabilized athletic shoes were initially conceived to protect ankles, knees, hips and spine from the repetitive torsional and shocking forces found in running.
A certain three-legged cocker spaniel named Tubby found out about torsional waves the hard way: Tubby was the only fatality when the Tacoma Narrows Bridge in Washington state collapsed in 1940, wrecked by torsional (twisting) waves and resonances.
But beyond that, they divide into three distinct types: transverse, longitudinal and torsional.
