Torsion Stiffness of a Protein Pair Determined by Magnetic Particles [PDF]
Biophysical Journal, 2011 We demonstrate the ability to measure torsion stiffness of a protein complex by applying a controlled torque on a magnetic particle. As a model system we use protein G bound to an IgG antibody. The protein pair is held between a magnetic particle and a polystyrene substrate. The angular orientation of the magnetic particle shows an oscillating behavior

Torsional stiffness of steel cords.
Journal of the Japan Society for Composite Materials, 1988 The steel cord has been widely used as a reinforcing fiber of the radial tire belt structure which is a FRR composite laminate. In this study, the torsional stiffness of steel cords having single or double layers were analyzed and verified by experimental results. Two loading cases of the regular and the reverse torsions were treated separately. In the

Analysis of Torsional Vibration for Crankshaft (Study of Torsional Stiffness)
JOURNAL OF THE MARINE ENGINEERING SOCIETY IN JAPAN, 1983 Various experimental equations (designated as experimental equations hereinafter) have hitherto been applied on torsional stiffness calculations of crank shaft in the form of equivalent length. However, all of these experimental equations had been obtained more than 50 years ago.

Identification of wind turbine main-shaft torsional loads from high-frequency SCADA (supervisory control and data acquisition) measurements using an inverse-problem approach [PDF]
Wind Energy Science, 2021 To assess the structural health and remaining useful life of wind turbines within wind farms, the site-specific structural response and modal parameters of the primary structures are required.
