Machine Design

About Machine Design

This simple tool will allow you to size common machine design components and evaluate the stresses for each scenario.

PROFESSIONALS
Quickly size common machine design elements such as threads and interference fits and evaluate their stress conditions in seconds. As always, with built-in unit conversions, never worry about the unit scale again.

POST SECONDARY STUDENTS (Mechanical, Aerospace, Civil Engineering, etc...)
Make your problem sets, labs and design projects a breeze with pre-written formulae which are commonly taught in engineering schools. Improve the quality of your designs by including industry proven design components sized to suite your specific need early in the design stage.

Simplify your engineering calculations with:
- Reference equations & diagrams
- Integration of sub-equations - (Press the |Sub| button)
- Dynamic calculation
- Built-in unit conversion
- Prominent tabbed output display
- Simplified main screen layout with icons for quick identification
- Built-in component sizing and form standards

Either for reference or for double-checking, conveniently view each diagram and equation at the bottom of each calculator's screen in an easy to read graphical layout like you see in reference textbooks.

With the integration of sub-equations, you can benefit from the added ease of determining critical design inputs through additional equations if you have not determined the specific value beforehand. (Press the |Sub| button)

Dynamic calculation allows you to vary design parameters rapidly and see their result without ever having to re-calculate.

Input your parameters in standard units of measure in engineering without having to do your own conversions.

The prominent tabbed output display makes the answer always directly at hand by displaying the output(s) at the top of the screen. By grouping calculators that can output multiple design parameters in a compact and easy to use "tabbed" display, you can "swipe or tap" left and right on the output field and view all of your results.

Included calculators:

1. Shaft Power
2. Shaft Torque
3. Parallel Key Sizing (USA Std., British Std.)
4. Parallel Key Stress
5. Spline Engagement Length
6. Spline Shear Stress
7. Interference Fit Pressure
