Vehicles
Engines, turbines and everything that moves you.
- How a 4-Stroke Engine Works — Suck, squeeze, bang, blow — the four strokes that power almost every car on the road, running live under your fingertip.
- How a Jet Engine Works — Suck, squeeze, bang, blow — the same four beats as a piston engine, but happening all at once, continuously, at 10,000 RPM.
- How a Manual Gearbox Works — Five speeds, three shafts and a brass ring that kisses gears up to speed — how a stick-shift trades engine revs for wheel torque.
- How a Turbocharger Works — A windmill in the exhaust, spinning a fan in the intake — one shaft between them at 200,000 rpm, riding on nothing but a six-micron film of oil.
- How a V-Twin Engine Works — Two cylinders, one shared crankpin, and a 90° secret: why a V-twin balances itself perfectly — and why it thumps with that offbeat heartbeat.
- How an Automatic Transmission Works — No clutch pedal, no lever — a doughnut of spinning oil and two gear sets that change ratio by holding one part perfectly still.
- How Car Suspension Works — A spring that turns a pothole into a slow squeeze, a tube of oil that refuses to give the energy back, and a 22 mm bar that only wakes up when the two sides of the car disagree.
- How Disc Brakes Work — Your foot, a column of fluid, and a 27× force multiplier ending in two pads squeezing a spinning iron disc — how a car turns motion into heat, on demand, hundreds of times a day.
