Please say which screen, what you entered and what you expected — a screenshot
answers all three at once.
Before you write
A result shows — or ∞. That is an
answer, not a fault: the app puts the reason beside it. The
theory manual lists every such edge.
A number looks a thousand times out. Check the units. The
app works in newtons and millimetres throughout; a second moment from a section
table is usually quoted in cm⁴, which is 10⁴ times smaller.
Two screens disagree. They should not, and that is worth an
email. Say which two.
What this app does not do
It is a mechanics tool, not a design-code checker. It applies no national or
regional standard, computes no allowable stress, and applies no load factors.
Every relation in it is mechanics; the
theory manual says exactly which.
Requirements
macOS 14 or later, iPadOS 17 or later. No network connection is needed or
used.
