• 🍽️ The design of a hollow shaft involves calculating the outer and inner diameters based on the applied bending and torsional moments.
• 🎨 Preferred series values are often used for practical designs.
• 🍽️ Rigidity considerations could further impact the selection of inner and outer diameters.
• 🎨 The final design aims to ensure the safety and reliability of the hollow shaft.
• ❓ The outer diameter is inversely proportional to the maximum shear stress and maximum torque.

Questions & Answers

Q: What theories are used to design the hollow shaft?

The maximum principle stress theory and maximum shear stress theory are used to design the hollow shaft.

Q: What is the outer diameter of the shaft?

The outer diameter of the shaft is determined to be 50mm.

Q: How is the inner diameter calculated?

The inner diameter is calculated to be 30mm using the provided relation between the inner and outer diameter.

Q: How is the final design selected?

The final design is based on the logic that greater values of the outer and inner diameter result in a safer component. Therefore, the chosen values are an outer diameter of 52mm and an inner diameter of 31.2mm.
