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 ...

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 ...
