Torque is a moment that twists a structure. Unlike axial loads which produce a uniform, or average, stress over the cross section of the object, a torque creates a distribution of stress over the cross section. To keep things simple, we're going to focus on structures with a circular cross section, often called rods or shafts.

The angle of twist is the measure of angular deformation formed in an object by a couple of twisting torques. The twisting torque cause torsional shear, which results in the twisting of an object. The angle of twist gives the rotation angle turned by planes of application of twisting torque. The term angle of twist is denoted by the symbol ‘θ’ and ...
a] Shaft with same cross-section and internal torque: For the shaft with a length of L, Modulus of rigidity G, and Polar moment of inertiaof J, the angle of twist is given by, θ=TLGJθ=TLGJ b] Shaft with changing cross-section and internal torque: For the shaft with different cross-section steps and with n number of twisting torque, the angle of twi...
The angle of twist in an object subjected to the torsional load depends on the following factors: 1. Internal torque:Higher the torque, the angle of twist in the object will be higher. 2. Length of shaft: The twist angle increases with an increase in the length of the shaft. Hence longer shafts show higher twisting than shorter shafts. 3. Material ...
Here are the steps to calculate the angle of twist (θ) in a shaft. 1] Divide the shaft into a number of sections (if necessary): If the object is experiencing multiple torques, then divide the shaft into sections, in such a way that each section will experience constant internal torque. If the object has different steps of cross-section, then also ...
Following are the angle of twist for the shaft’s different cross sections. 1] Circular shaft: a] The J for the solid circular shaft of diameter ‘d’ is given by, J=π32.d4J=π32.d4 Thus the angle of twist for the solid circular shaftis given by, θ=TLGJ=TLG.32π.d4θ=TLGJ=TLG.32π.d4 θ=32TLπ.G.d4θ=32TLπ.G.d4 b] The J for the hollow circular shaft of outer...
The below figure will help you to understand the difference between the angle of twist and the angle of shear. Line AB in the figure is the initial reference line drawn onto the surface of the cylinder before twisting that is parallel to the axis of the cylinder. Here one end of the cylinder is fixed and another end is subjected to the torque T. Af...
1) The aluminum shaft of length 1 m, G = 24 GPa, and having a diameter of 40 mm is twisted by the torque of 100 N.m. Find the twist angle (θ) in the shaft. Given: G = 24 GPa= 24 × 10³ N/mm² d = 40 mm T = 100 N.m = 100 × 10³ N.mm L = 1 m = 1000 mm Solution:– Step 1]Polar moment of inertia: For circle, J=(π32)d4=(π32)404J=(π32)d4=(π32)404 J = 251327 ...
Oct 12, 2018 · Twist describes the relative trim of the sail from high to low. A sail has lots of twist when the upper part of the leech is open, while a closed leech has little twist. Increasing twist reduces power because it opens the upper part of the sail. More Twist = Less Power.

A shaft of length \(L\), diameter \(d\), and shear modulus \(G\) is loaded with a uniformly distributed twisting moment of \(T_0\) (N-m/m). (The twisting moment \(T(x)\) at a distance \(x\) from the free end is therefore \(T_0x\).) Find the angle of twist at the free end.

Explanation. A twisted pair can be used as a balanced line, which as part of a balanced circuit can greatly reduce the effect of noise currents induced on the line by coupling of electric or magnetic fields. The idea is that the currents induced in each of the two wires are very nearly equal.
