1.Input the required parameters into the app. The required parameters include:

• Diameter of the shaft: This is the diameter of the shaft in meters (m).
• Length of the shaft: This is the length of the shaft in meters (m).
• Load: This is the load acting on the shaft in Newtons (N).
• Torque: This is the torque acting on the shaft in Newton-meters (Nm).
• Young's modulus: This is the Young's modulus of the material of the shaft in Pascals (Pa).
• Yield strength: This is the yield strength of the material of the shaft in Pascals (Pa).
• Factor of safety: This is the factor of safety that you want to use in the design.
• Design standards: This is the design standards that you want to use in the design.

2.Click the "Calculate" button to run the calculation.

3.The app will output the bending stress, allowable bending stress, safety factor, and result of the design.

• Bending stress: This is the bending stress in the shaft, calculated using the input parameters.
• Allowable bending stress: This is the allowable bending stress based on the design standards and factor of safety that you selected.
• Safety factor: This is the ratio of the allowable bending stress to the actual bending stress. If the safety factor is greater than 1, it means that the design is safe. If the safety factor is less than 1, it means that the design is not safe.
• Result: This is the result of the design, based on the safety factor. If the safety factor is greater than 1, the result will be "Design is safe". If the safety factor is less than 1, the result will be "Design is not safe".

That's it! You can use this app to quickly and easily calculate the safety of a machine design based on the input parameters. It is important to note that this app is intended for reference purposes only and is not a substitute for professional engineering advice.
