How can I ensure that the engine shaft is sturdy for high rotational speed?

 In the context of selenium, you can ensure that the shaft of the engine is sturdy enough to withstand high rotational speeds by performing stress analysis by using finite element analysis techniques. This would involve modeling the shaft geometry, applying the right or appropriate loads and conditions of boundaries, and even analyzing the stress distribution to ensure that it should remain within the safe limit.

In terms of coding you can choose to use software like ANSYS, abacus, or even Solidworks simulation to perform the FEA analysis. Here is a basic example given by using the Python coding with the package “abacus- python”:

From abaqus import *

From abaqusConstants import *

# Create shaft geometry and mesh it

# Apply boundary conditions and loads

# Define material properties

# Run the analysis

# Extract stress and deformation results
