Automotive Engineering: Automobile Fundamentals

Explore two-dimensional forces, including traction, drag, weight, normal force, lift, and friction, that drive car motion and show how slope affects weight components via sine and cosine under Newton's laws.

Analyze static lateral forces on a car, including cornering and centripetal forces, balance on horizontal and banked tracks, and how camber angles affect grip, steering, and stability.

Explore how wheel motion combines rotation and translation under the no slipping condition, linking angular and linear velocity. Understand friction, rolling resistance, normal force, and tire grip.

Explore D'alembert's principle in vehicle dynamics, linking external and inertial forces to acceleration, center of gravity, and how mass distribution affects braking, traction, and handling.

Explore vehicle chassis fundamentals, including six design requirements, rolling chassis and powertrain concepts, and diverse chassis types from ladder frames to monocoque shells.

Explore materials and mechanical properties essential to chassis design, and learn how Young's modulus and tensile strength guide steel, aluminum, magnesium, titanium, and composites.

Analyze axles as the connection between wheels and the car body, covering drive and dead axles, front and rear roles, and how loads and power transmit to the wheels.

Examine disc and drum brake systems, hydraulic operation from master cylinder to pistons, and how friction and heat dissipation, plus material choices and cost, influence front and rear braking.

Explore how petrol and diesel engines convert fuel and air into motion, through four-stroke and two-stroke cycles, and key components such as pistons, crankshaft, valves, camshaft.

Explore how the engine converts chemical energy to mechanical energy and transmits torque through the flywheel, clutch, gearbox, and differential to the wheels, balancing torque and wheel speed.

We cover the drivetrain components: flywheel, clutch, transmission and gearbox, differential, and driveshaft, and explain how they transfer power from the engine to the wheels.

Explore how the flywheel transfers engine energy to the gearbox, and how the clutch disc, pressure plate, and diaphragm spring engage or disengage to permit gear changes.

Explore how the clutch and gearbox disengage and engage engine power, use gear ratios to control speed and torque, and connect input to output via synchronizers and a counter shaft.

The differential, a passive gear set between the engine and drive shaft, balances left and right wheel speeds to enable turning, automatically accommodating speed differences via spider gears.

Explore steering fundamentals, Ackermann geometry, and the evolution from mechanical linkage to hydraulic, electric, and steer-by-wire systems, including components like steering wheel, column, worm gear, Pitman arm, and tie rods.

Explore how cars work by examining air and fuel induction, exhaust, electrical, cooling, and lubrication systems, and discover automotive systems and aircraft systems courses.
