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 ...

Torsional stress-strain curves will be plotted. The effect of sample geometry on the response of the component will be compared to theoretical models.

If the door isn’t balanced correctly, one spring may take on more strain than the other, which leads to uneven wear and premature failure. A garage door torsion springs are under constant stress ...

The Epsilon axial/torsional extensometer was engineered to directly measure the shear strain, γ, as illustrated in the figure. This design allows the correct determination of the shear strain without ...
