Mohr's Circle Stress Analysis:

-Stress state to Mohr's Circle presentation by tapping on screen at any instant (on 2D and 3D graph presentation views).
-2D Mohr's Circle Stress Analysis.
-3D Mohr's Circle Stress Analysis.
-2D transformations on Mohr's Circle and Stress State View.
-Optional sign conventions.
-Shows calculations on formula sheet
-Multiple sharing options including airport transfer, can open its pdf export file on other available applications (i.e. pdf editors).
-Saves and restores input data.

Goodman Fatigue Analysis Diagram:

-Calculations can be carried with either “residual stress method” or “nominal mean stress method”. 
-Goodman Diagram constructed automatically once all parameter are entered and intersection points are calculated and given on diagram for judgement.

Bolted Joint Analysis:

-Bolted Joint Analysis gives a force diagram and result of its simple calculations for a clamped system under axial external loads. It also gives basic terminology and information to have a better visibility of subjects.
