When every student gets the same numbers, answers travel faster than understanding. AdaptIQ’s biomechanics module generates a fresh statics problem for every student and every attempt — and checks the answer on the server.
A shared problem set has a well-known weakness: the answer to question 4 is the same for everyone, so it spreads. In engineering mechanics, where students learn by solving many similar problems, that matters. The Statics Drill in AdaptIQ’s biomechanics module takes a different approach: the problem is generated, so every student — and every attempt — gets numbers of their own.
Seeds, not answer sheets
A statics exercise stores a generator and a variant, never an answer. When a student opens it, the server builds an instance from a seed — the loads, the lengths, the angles — and shows it. When the student answers, the server rebuilds exactly the same instance from the same seed and recomputes the solution. The grade is computed there, never taken from the browser.
This matters for fairness as much as for security. Until the student answers, their browser never holds the correct result, so there is nothing to find in the page source.
What a problem looks like
Every problem comes with a figure generated as SVG, a hint, and a step-by-step worked solution that appears after answering. Numeric answers count as correct within ±1.5%, angles within ±0.8°, so reasonable rounding does not cost a point.
A typical example is a simply supported beam: a force at some distance from support A, a span between the supports, and a question asking for the vertical reaction at A. Two students sitting side by side see the same kind of beam with different numbers, and have to work through the moment equation themselves.
Seventeen generators, seven topics
The catalogue covers the core of introductory statics: forces and their components, moments, resultants, couples and the reduction of force systems, the equilibrium of beams, three forces and frames, and four-force problems solved with the methods of Ritter and Culmann. Examples include a simply supported beam, a cantilever, and a plate on three rods.
In the course, the problems sit inside a nine-topic pathway that ends in an exam, next to lessons that explain the method before students practise it.
Teachers stay in control
A teacher adds a statics problem like any other exercise: pick the generator and the variant, and the platform does the rest. The teacher’s AI assistant can propose statics problems too, choosing from the same catalogue — and like everything the AI drafts, they wait for a teacher’s approval before students see them.
A module, not a special case
The Statics Drill is our own work (AdapTech Systems, 2026). It also shows how subject modules work: a module brings its own exercise types, tools and pages into the platform, while students keep the same pathway map, the same progress and the same review queue.
Generated problems will not replace a good teacher at the blackboard. They make sure the practice after the lecture is each student’s own.
