Interactive mechanical engineering
Learn mechanical engineering by experimenting.
Short, hands-on lessons that build intuition with live models and then check your engineering calculations step by step. Start with torque and rotational power.
The sample lesson works without an account; sign in to save progress and unlock the next lesson.
Example question from the sample lesson
A 180 N force acts 0.35 m from a bolt at 70° to the wrench. What torque does it apply?
You answer with a value and a unit. Hints, feedback on common mistakes and a worked solution are built in.
Move it, then read it
Drag a force, a lever length or a shaft speed and watch the model respond before you meet the equation.
Real calculations with units
Answers are checked numerically with unit awareness: Nm, N·mm and kN·m are all understood, and a wrong unit is explained, not just marked wrong.
Progress that follows you
Sign in on a phone or a laptop and continue on the exact step you left. Hints never cost you points.
What is available today
One course, two lessons, two live simulations and a full account system are built and working. The wider curriculum, Arabic and offline support are planned; each is labelled as planned wherever it appears.
