Deflection vs LinkGuardian

Deflection is a powerful, versatile calculator for beams, 2D trusses, and 2D frames. The interface is simple and intuitive, and the graphical output is state-of-the-art. In addition to reaction, shear, bending moment, and deflection results, Deflection also computes internal shear and bending stress along the cross section and along the beam. 2D FRAME AND TRUSS EDITOR The 2D editor is seamlessly integrated with the beam editor. Draw arbitrary frame and truss structures and apply loads and constraints using the same simple interface as for beams. You can visualize results directly within the 2D editor, or you can select a beam and get additional insights. INTERNAL STRESSES Obtain internal bending and shear stress diagrams in addition to shear, bending, and deflection diagrams. The internal stresses can be visualized along the length of the beam as well as along the vertical axis of the cross section using the beam editor. CROSS SECTION EDITOR Edit built-in cross sections. Moment of inertia and area values are automatically calculated and applied to the rest of the beam calculations. MORE FEATURES • The built-in database contains more data for your reference and convenience. • Apply beam self-weight optionally • Unlimited design files • Quick-start templates CONTACT We like to hear from you!

Scan any link, QR code, or website before you open it. Analyse phone numbers, emails, and Wi-Fi networks. Stay informed with a live global intelligence feed. LinkGuardian runs entirely on your device — nothing is sent to any server. Your inbox, WhatsApp, and SMS are full of links you didn't ask for. One tap on the wrong one can expose your passwords, bank account, or identity. LinkGuardian gives you the power to check first, open second — in seconds. LINK SCANNER Paste any URL and run it through 15 threat-detection modules. Detects phishing, brand impersonation, suspicious domains, hidden redirects, missing HTTPS, and malicious TLDs. Trusted domains get instant Safe verdicts. No false positives. QR CODE DEEP SCANNER Most QR scanners open links immediately. LinkGuardian pauses, runs a full threat analysis, and shows you the result before anything happens. Also reads Wi-Fi QR codes, vCard contacts, and plain text.
