◉ Scanning is optional — you don't have to scan. You can input the whole truss yourself (joints, members, loads) for free. Scan just uses AI to fill it in for you from a photo — about 95% accurate. It does not solve, and it does not read member areas — type each A (and E) in the Members table. Check everything against your figure, fix any mistakes, then press Calculate Forces & Deflections.

💡 Scan and Solve are charged separately — Scan costs 10 EP, Calculate Forces & Deflections costs 10 EP. One solve charge covers the bar forces, every joint displacement, and both step-by-step solutions. Build the truss yourself and you only pay the 10 EP to solve.

📱
Please rotate your phone
The Truss Deflection Solver works best in landscape so the whole truss fits on screen. Turn your phone sideways to continue.
📱 Using the Truss Deflection Solver on a phone

This app is easier on a desktop or laptop, where you can draw and edit the truss directly on the board. On a phone that drawing isn't practical — so on mobile you build the truss with the buttons instead. It still works fully; it's just a little more tapping.

Tap Input Joints, then Assign Members + Areas (type each member's area A and the modulus E there too), then Input Joint Loads — or let Scan auto-fill the truss for you. When you're ready, tap Solve / Results — or Joint Displacements to jump straight to every joint's δ by virtual work, with the full step-by-step under Detailed Solution.

⚠️ Review before you solve

Solving will spend 10 Ebora Points. This single charge covers the Results, every joint displacement, and both step-by-step solutions (Method of Joints + Virtual Work).

Quick check before you spend:

  • Your joints and their supports (pin / roller) are right.
  • Every member connects the correct two joints.
  • Each member's area A and the modulus E are entered. (Fixing A or E after solving updates the deflections for free.)
  • Your joint loads (size and direction) match your figure.
✂️ Crop — draw a box around just the truss
Drag to select. Resize using corner handles. Anything outside the box is ignored.
⚠️ About the EboraBot Scanner

You don't need to scan. You can input the joints, members, supports and loads yourself for free — scanning is an optional paid shortcut that types them in for you.

EboraBot uses AI to fill in your truss — the joints, members, supports and loads — so you don't have to type a big problem by hand. It inputs the truss for you; it does not solve it.

  • Accuracy is about 95%. On a dense diagram it can misread a number, a load angle, a support, or which way a diagonal runs.
  • You must visually check everything it fills in — compare the joints, members, supports and loads against your figure and fix anything wrong.
  • Only after you've verified it do you press Calculate Forces to solve.
  • Scanning and solving are charged separately in Ebora Points, so review carefully before you solve.
