In the problem, the shear modulus G and the angle of twist [theta] were assumed to be unity.
In the methodology, an angle of twist is assumed for shear stress through the solid or hollow cylindrical bars.
Assuming the angle of twist, torque and the length of the both shafts are same Torque transmitted by solid structural steel shaft, [T.sub.3] = [(C x [THETA])/L] x [J.sub.1] (6)
The considered cable KOBDF-6 has the following characteristics : conducting core of construction 1+6; wires diameter [delta] = 0.35 mm; angle of twist of layer [alpha] = 19[degrees]; modulus of elasticity of wires E =1.3 x [10.sup.5] MPa; yield stress [[sigma].sub.T] = 100 MPa.
It was only after Whittle realised that British Thomson-Houston had made the blades to a steam turbine profile instead of to his own radical profile (doubling the angle of twist) that predicted results were obtained and serious backing became possible.
The angle of twist is 360[degrees] over a length of 7.5,10, and 12.5 cm to produce the twist ratios in 2.93,3.91, and 4.89.
This research focuses on the important factors such as twist angle which can affect size of stretching and slipping zones and defines the relation of strength with angle of twist.
Even quite small change in angle of twist can have significant impact.
This continues till [theta]=45[degrees] and beyond this angle of twist, the decrease in the positive wetted area of the front projected area is more than the increase in the positive wetted area of the side projected area.
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.
The ultimate aim is to achieve a braid angle known as the "neutral angle of twist", namely 54.7[degrees], which is measured from the longitudinal line of the hose.
