The torsional rigidity of a pump shaft is determined through a series of tests and calculations. These typically involve applying a known torque to the shaft and measuring the resulting angular deflection. By analyzing the relationship between the applied torque and the resulting deflection, the torsional rigidity can be calculated. Additionally, the material properties of the shaft, such as its modulus of elasticity and dimensions, are taken into consideration to determine the torsional rigidity accurately.
