Pricing
You pay for the solution, not for the attempt. Drawing, knowing whether a structure is statically determinate and knowing why it is unstable stay free for good.

Questions
- What is a credit?
- One solved structure. It is charged once only: redrawing the same scheme, reloading the page or coming back tomorrow does not start paying again.
- What stays free?
- Drawing as much as you like, the verdict on the structure, the count of degrees of freedom and restraints, and the explanation of why a structure is unstable.
- Can I use it in an exam?
- It is built for studying, not for copying: it shows the working step by step so you can redo it by hand. Exam rules are your lecturer's call.
