Engineering module
Shaft Hub Fit
Closed-form or FEM estimates without a specific design code claim. Applies recommended default units when you change standard; unit dropdowns stay fully editable.
Shaft hub fit
Estimate contact pressure, friction torque and assembly force for an interference fit.
Shaft hub fits
Uses thick-cylinder Lame solution for contact pressure from diametral interference. Friction torque T = p·π·d·L·μ·d/2. Verify assembly temperature rise and hub yield for high interference.

Module quality
60%Unit integrity
All solver inputs/outputs normalized and converted through shared unit contracts.
Physics validation
Engines expose explicit validation and solver-check metadata.
Chart conformance
Plots use shared professional styling and consistent axis/legend language.
Pictorial input/output
Module includes schematic inputs and color-coded output visualizations.
Export consistency
Reports include the same KPIs, units, and visuals as on-screen results.
Enter hub geometry and interference, then calculate.
