About this app

This quick and easy tool will allow you to calculate the resultant forces and stresses encountered in many common design scenarios.

PROFESSIONALS
Quickly and accurately analyze the stress levels in common design elements and forces which result from real-world scenarios like impact loading and buckling. 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 considering multiple failure modes at the design stage quickly, and easily.

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 Cross-section property calculators

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.

Simplify your calculations with built-in cross-section property calculators for a wide variety of standard shapes and never have to calculate area (A) or area moment of inertia (I) by hand again. All you need to press is the |Sub| button beside the cross-section property of interest.
