Calculate the angular deflection of a hollow shaft with this free calculator. Quickly and easily find the angular deflection of your shaft in a few simple steps.
When an expansion joint bends around its center, located on the centerline and halfway between the ends of the bellows, it is known as angular deflection. To calculate the angular deflection of a hollow shaft, you can use the online Angular Deflection of Hollow Cylinder Calculator. All you need is the Applied Torque (T), Shear Modulus (G), Outside Diameter (D), Inside Diameter (d), and Unsupported Length (L).
- α is the deflection of the shaft
- T is the applied torque
- L is the unsupported length of the shaft
- G is the shear modulus of the shaft material
- D is the outside diameter of the shaft
- d is the inside diameter of the shaft.
- T: The applied torque is the twisting force that is applied to the shaft. It is measured in units of force multiplied by distance, such as newton-meters or pound-feet.
- L: The unsupported length of the shaft is the distance between the points where the shaft is supported. If the shaft is supported at both ends, then the unsupported length is equal to the total length of the shaft.
- G: The shear modulus of the shaft material is a measure of the material’s resistance to shearing or twisting forces. It is measured in units of pressure, such as pascals or pounds per square inch.
- D and d: The outside diameter and inside diameter of the shaft respectively are the dimensions of the shaft’s cross-sectional area. The difference between the two is known as the wall thickness of the shaft.
