The Solid Mechanics PLUS version takes the strong foundation built with Solid Mechanics and enhances it through the ability to REARRANGE ANY EQUATION, solving for any variable you desire.

This simple yet powerful tool will allow you to swiftly calculate engineering stresses, strains and others for a multitude of loading conditions.


Quickly and accurately perform "back of the envelope" calculations, or quick checks with ease using the fully rearrangeable equations, built in unit conversion and One-Touch main screen function access.

POST SECONDARY STUDENTS ( Mechanical, Aerospace, Civil Engineering, etc... )

Make your problem sets, labs and design projects a breeze with multiple pre-programmed common loading conditions, cross-sections and formula display.

Make all of your engineering stress and strain calculations simple, featuring:

  • Rearrangeable equations – (Press and hold on any variable you want to solve for)
  • Reference equations & diagrams
  • Integration of sub-equations - (Press the |Sub| button)
  • Standard loading conditions for tensile, compressive and shear stresses
  • Built-in unit conversion
  • Dynamic calculation
  • Prominent tabbed output display (swipe to change outputs)
  • Simplified main screen layout with icons for quick identification
  • Built-in Cross-section property calculators

With the enhanced rearranging of equations, you can now solve for the most critical variables for your design at the touch of a button. You will save the time and headaches of trying to rearrange equations by hand or guessing multiple different design parameters. (Press and hold on any variable you want to solve for)
