NASA and Southwest Research Institute (SwRI) engineers fit a linearized model of a mechanical analog
for sloshing dynamics to data taken from SSTR runs to identify model parameters and characterize sloshing motion.
By utilizing German precision engineering, our lower-priced mechanical analog
scales will also appeal to the mass merchants who are tired of 'spinning' retail dollars by selling inexpensive and inaccurate scales prone to high return rates," Helfman said.
As a step toward learning whether the same kind of surprising result could occur in a biological system, Cohen started by looking for a mechanical analog
of the traffic paradox, and he came up with the string-spring arrangement described above.
