In summary, the internal diameter of a hollow shaft does not affect the maximum torque that can be transmitted. The torque is applied to the outermost fibers of the shaft, making hollow shafts a cheaper alternative to solid ones. However, the internal diameter does have an impact on the stress distribution and deformation of the shaft due to the torque, as it is related to the polar moment of inertia.

I don think it does, the torque is applied to the outermost fibers of the shaft, which is why a lot of shafts aren't solid but hollow. It is also cheaper to make.

Like it has been mentioned, it does not effect the maximum torque allowable. What it does have an effect on is the stress distribution and the deformation in the shaft created by the torque because they are a function of the polar moment of inertia.
 

FAQ: Hollow Shaft Internal Diameter and Its Impact on Maximum Torque Transmission

What is a hollow tube?

A hollow tube is a cylindrical structure with an empty space in the center. It is typically made of a strong, lightweight material such as metal or plastic and is used for various purposes, including as a structural support, conduit for fluids or gases, and in engineering applications.

How is torque related to hollow tubes?

Torque is a measure of the force that causes an object to rotate around an axis. In the case of hollow tubes, when an external force is applied to one end of the tube, it creates a torque that causes the tube to twist along its length. The magnitude of this torque depends on factors such as the material of the tube, its diameter, and the applied force.

What are some examples of hollow tubes used in everyday life?

Hollow tubes are used in a variety of everyday objects, including pipes for plumbing and irrigation systems, bicycle frames, tent poles, and drinking straws. They are also a crucial component in many industrial machines and tools, such as drills, pumps, and turbines.

How do engineers use hollow tubes to increase strength?

Engineers often use hollow tubes to increase the strength of a structure while minimizing its weight. By using a hollow tube instead of a solid rod, they can distribute the material more efficiently, reducing the overall weight without sacrificing strength. Additionally, the hollow center of the tube can be used to route cables or other components, further optimizing the design.

Can hollow tubes fail under torque?

Yes, hollow tubes can fail under torque if the applied force exceeds their strength. This can result in the tube deforming or breaking, which can be dangerous in certain applications. Engineers must carefully consider the expected torque and choose a tube with appropriate strength and material to avoid failure.
