Strix is an application filled with data
Here are the core areas included...
Strength Theory
Beam deflection across 15+ load cases, column buckling with Euler's theory, and stress analysis including fatigue and fracture mechanics.
Machine Elements
Bolt sizing per VDI 2230, gear ratio calculations for spur, belt, and chain drives, plus circlip reference data to DIN 471/472.
Material
Searchable reference of material properties: Young's modulus, shear modulus, Poisson's ratio, yield strength, hardness, and more.
Math
50+ formula sheets covering geometry, trigonometry, and algebra — plus a symbolic calculator with step-by-step solutions.
Mechanics
Physics formula reference, 40+ physical constants, and a library of 200+ engineering quantities across mechanics, thermodynamics, and fluid mechanics.
Technical Drawings
Weld sizing and type selection for fillet, V, butt, and other joints — including intermittent weld calculations.

RegisterFAQ
What is Strix?
Strix is a digital engineering toolkit for mechanical engineers. It brings calculations, formula sheets, standards data, and reference tables into one application — replacing the workflow of searching through physical handbooks and scattered resources.
What tools and calculators are included?
Strix includes tools for beam deflection (15+ load cases), column buckling, bolt sizing (VDI 2230), weld sizing, gear ratio calculations, circlip reference data (DIN 471/472), cross-section properties, and a unit converter. On the reference side you get formula sheets for math and physics, a library of 200+ engineering quantities, 40+ physical constants, and a symbolic calculator with step-by-step solutions.
Is there a free trial?
Yes. The Personal plan includes a 30-day free trial — no credit card required to get started. You get full access to all tools during the trial period.
What is the difference between the Personal and Organisation plans?
The Personal plan is for individual engineers and includes all calculators, reference tools, and a personal notes workspace. The Organisation plan adds a shared team workspace, seat-based licensing, member invitations, and admin controls — designed for engineering teams and companies.

Bästa hjälpmedlet på länge
Äntligen ett verktyg som faktiskt förstår vad man frågar om. Perfekt för oss som jobbar med hållfasthetsberäkningar dagligen.
