The optimum angle of twist at which the efficiency and the output power is maximum is evaluated.
Hence, the high RPM and high Torque are obtained at an angle of twist of 45[degrees].
Eight test methods outline procedures for determining susceptibility to stress corrosion cracking, angle of twist
, formability, bending fatigue, expansion, and deviations from flatness.
The values of shear stress, [tau], and shear strain, [gamma], at the middle of the wall thickness were calculated from torsional moment and angle of twist
on the assumption of iso-volume of the twisted specimen, because the hollow cylinder under twisting shows no dilatation, as it is essentially in simple shear.
Angle of twist and twists per centimetre are not determinable.
Its angle of twist is 55 [degrees] and there are two twists/cm.
We calculated the values of shear stress, [tau], and shear strain, [gamma], at the middle of the wall thickness from the torsional moment and the angle of twist
, assuming an iso-volume of the twisted specimen (the hollow cylinder under twisting shows no dilatation because it is essentially in simple shear).
Bow, crook, and the angle of twist did not significantly differ between the two groups.
The magnitude of distortion, defined as bow, crook, twist, and angle of twist, depends on complex interactions between moisture content, wood species, and wood anatomical characteristics.
Additionally, in accordance with the prescribed method of Merforth (2000), the angle of twist [alpha] (Fig.
Range in angle of twists (warps): 28 [degrees]-29 [degrees]
Range and mean angle of twists (weft plies): not applicable
