Resultant is a free suite of statics and mechanics calculators that run entirely in your browser.
Grounded in available product and source data
Most online statics and mechanics calculators require signing up, lock export behind a paywall, or produce diagrams too small to actually use in a report — free statics and mechanics calculators, no account, is Resultant's direct response to that frustration.
The toolset covers most of an undergraduate statics and mechanics course in one place. A Free Body Diagram Creator handles force arrows, moment arcs, and geometry shapes with grid-snapping and clean PNG/SVG export; a Shear and Moment Diagram Calculator solves reactions analytically and plots V(x) and M(x) with labeled critical values across simply supported, pin-roller, and cantilever beam types; and a Mohr's Circle Calculator reports principal stresses and orientation angles with interactive dragging to read transformed values directly rather than computing them by hand.
Beyond the core statics tools, a Beam Formula Calculator references standard cases from Roark's Formulas for Stress and Strain and solves for any variable, an Inertia and Centroid Calculator builds composite sections and computes centroid and moment-of-inertia values live, and a Thermodynamics Solver handles Rankine cycle analysis using IAPWS-IF97 steam data entirely client-side. An Equation of Motion and Transfer Function Solver rounds out the mechanical-systems side, generating a full Laplace transform and transfer function from a single-inertia system description.
Every calculation runs in the browser itself, with the site stating explicitly that no data gets transmitted to a server — useful for anyone wary of uploading coursework data anywhere. A 140-question strength-of-materials quiz aligned to Hibbeler's Mechanics of Materials (chapters 1-14) adds a practice component beyond the calculators themselves. The whole suite requires no account or installation and is entirely free, with no tiers, paywalls, or export restrictions — a direct contrast to the gap the site describes in existing tools.
No — every tool is accessible directly with no account or installation required, which the site positions specifically against calculators that gate basic use behind a signup.
No — the site states computation runs entirely client-side in the browser, with nothing transmitted to a server, so inputs stay local to the device being used.
Full exports are included — PNG, SVG, and PDF formats depending on the specific tool, addressing exactly the 'diagrams too small to use in a report' problem the site calls out in existing alternatives.
Simply supported, pin-roller, and cantilever beams, under point loads, uniformly distributed loads, and applied moments, with piecewise symbolic expressions output for manual verification.
No — the entire suite is stated to be free with no tiers, paywalls, or account restrictions, unlike the tools the site specifically contrasts itself against.
