Consider the torsion of circular shafts. Because a circular cross section is an efficient shape for resisting torsional loads. Circular shafts are commonly used to transmit power in rotating machinery. Also discuss another important application－torsion of thin-walled tubes..
When a shaft is subjected to a torque or twisting a shearing stress is produced in the shaft. The shear stress varies from zero in the axis to a maximum at the outside surface of the shaft. The shear stress in a solid circular shaft in a given position can be expressed as: τ = T r / J (1) where.
Torsional Loads on Circular Shafts. Interested in stresses and strains of circular shafts subjected to twisting couples or torques. Turbine exerts torque T on the shaft. Shaft transmits the torque to the generator. Generator creates an equal and opposite torque T’.
THEORY OF TORSION FORMULA • The following conditions are used in the torsion of the circular shaft: 1. Sectional planes perpendicular to the axis of the shaft remain plane during torque application. 2. The shear strain varies linearly from a value of zero at the axis of the shaft to a maximum at the extreme radius . 3.
On completion of this tutorial you should be able to do the following. Derive the torsion equation. Derive polar second moment of area. Solve problems involving torque, shear stress and angle of twist. Derive the formula for the power transmitted by a shaft. Relate power transmission to torsion.
