Engineering & Mechanics
1) Mathematical topics that support Electrical Engineering & Mechanics - eg Fractions, decimals, percentages, indices, algebra, formulae, equations, graphs, vectors, trigonometry etc.
2) Electrical Engineering - symbols, current, voltage, potential difference, resistance, internal resistance, resistivity, measuring instruments, Ohm's Law, conductors, insulators, electrical power and energy, fuses, capacitors, parallel plate capacitor, capacitors in series & parallel, dielectric strength, energy stored, types and designs, discharging, inductance & inductors, induced emf. Use of the acronym CIVIL. Series & parallel resistance circuits, Kirchoff's laws. Electromagnetism, flux & flux density, magnetic fields. Alternating & direct current. Power factors - lead & lag. Impedance & resonance. Transformers. Power generation & transmission.
3) Heat Energy - temperature, specific heat, change of state, latent heat of fusion & evaporation.
4) Mechanics & Kinematics - speed, distance, time, velocity, acceleration, free-fall, equations of motion. Force, mass & acceleration. Newtons laws. Forces acting at a point, equilibrium, centre of gravity, resolution of forces. Simple supported beams, moment of a force. Linear and angular motion, centripetal force. Friction. Simple machines, pulleys, force and movement ratios, gears. Materials, stress, strain, tension, compression, shear, elasticity, Hooke's law, ductility, brittleness. Torque, couples. Kinetic and potential energy. Thermal expansion.
