Application problem calculation programme

Dear programmers.
My project is primarily concerned with programmers-physicists or programmers-mechanics.
This is not a requirement, as there is an algorithm for calculating.
So you need to write a program for calculating applied problems in theoremics (statics) and step-by-step output of the results of your work.
The program must be able to work with the schedule.
The language of writing the program is not fundamental.
In the future, there will be new TKs for new programs.
I'm waiting for your suggestions.
