Pick a subject and work through it one concept at a time. Every lesson starts from real life, lets you experiment, and ends with a short quiz.
- Fluid Mechanics How liquids and gases flow, push and keep things afloat.
-
Engineering Mechanics Forces, balance and motion: the base of every machine.
-
Strength Of Materials Why beams bend, shafts twist and parts break.
-
Thermodynamics Heat, work and energy inside engines and fridges.
-
Theory Of Machines Gears, cams and linkages, and how motion is passed on.
-
Heat Transfer How heat moves by conduction, convection and radiation.
-
Machine Design Choosing shapes, sizes and materials that last.
-
Manufacturing Processes Casting, welding, machining and 3D printing.
-
Engineering Materials What metals, polymers and composites are made of inside.
-
Automobile Engineering Engines, gearboxes, brakes and suspension.
-
Refrigeration And Air Conditioning How cooling cycles move heat out of a room.
Fluid Mechanics lessons
Unit 1: Fluid Properties
- Why Does Honey Pour So Slowly? Water rushes out of a jar in a second. Honey takes its time. What is holding it back?
- How Does Water Climb Up A Thin Tube? Dip a tissue in tea and the tea climbs up it, against gravity. Where does that lift come from?
Unit 2: Fluid Statics
- Why Are Dams Thicker At The Bottom? A dam can be 30 metres thick at its base and only a few metres at the top. Why build it that way?
- How Does A Small Push Lift A Car? A mechanic lifts a one-tonne car with one hand on a hydraulic jack. Trick, or clever physics?
- Why Does A Steel Ship Float? A steel nail sinks in a second, yet a ship made of thousands of tonnes of steel floats. How?
