Some of the things covered in this video include how circular bars deform under torsion, how we can calculate the angle of twist, and how we can calculate the stresses and strains that are ...

The hypothesis used in developing the stress and strain in the shaft is that all points on a cross-section of the shaft experience the same angle of twist. The angle of twist for a section of length L ...

1. Twist equal to strain. The typical method of measuring torsional vibration in a power train shaft is to use strain gauges. Courtesy: GE Energy Each mode of vibration can be magnified by an ...

An international group of researchers have put a literal twist on this challenge, demonstrating a new nanoscale optomechanical resonator that can detect torsional motion at near state-of-the-art ...

Rotation is torsional, meaning that twist occurs in one direction until a limiting rotation results, and then rotation can be reversed by changing the applied voltage. Left and right hand yarns rotate ...

A far cheaper alternative to the more conventional interferometer-based devices, this “torsion-bar antenna” could plug a gap in the gravitational-wave spectrum – between the high-frequency waves ...

Until now, however, little was known about how water affects its torsional behaviour. The group demonstrated that applying stepwise changes in humidity caused the silk to immediately twist above a ...
