Mechanical Technology

This is ONE of the subjects at Oude Molen THS with the most accolades. It has the distinction of having its matric results being the tops in the Western Cape for the past decade.

What is Mechanical Technology?

Mechanical Technology focuses on concepts and principles in the mechanical (motor, mining, shipping, rail, power generation, etc.) environment and on technological processes. It embraces practical skills and the application of scientific principles. This subject aims to create and improve the engineering and manufacturing environment to enhance the quality of life of the individual and society and ensure the sustainable use of the natural environment. The TWO courses offered at Oude Molen THS are Fitting & Machining and Automotive. (click on links for more detailed information)

Specific Aims

The learner in Mechanical Technology needs to be interested in any form of mechanical entities. It can be cars, planes, trains, welding, maintenance, etc.

In order to be successful, the learner also has to enrol in Mathematics, Physical Science and Engineering Graphics and Design, as they all form part of the technical studying field.

Mechanical Technology in essence is applied science, as the field of work includes trigonometry, Newton’s laws and chemical equations when dealing with certain welding techniques, fuel combustion, fuel injection, cooling systems, etc.

The main topics in Mechanical Technology are:

  • safety – Occupational Health and Safety (OHS) Act;
  • tools and equipment;
  • materials – ferrous and non-ferrous materials and alloys and the iron-carbon equilibrium diagram;
  • terminology – manufacturing processes with reference to lathes (diameter turning, taper cutting, screw cutting) and milling machines (cutting methods, dividing head, centring of cutter);
  • joining methods – permanent (welding) and semi-permanent (bolts, nuts and rivets) joints;
  • forces – forces, moments, Young’s modulus, stress and strain;
  • maintenance;
  • systems and control:
    • mechanical – gears, belts, pulleys, power transmission, chains, clutches, cams, levers, etc;
    • hydraulics – pistons, valves, Pascal’s law;
    • pneumatics;
    • electrical wiring – starting and charging circuits; and
    • electronic applications – anti-lock braking system (ABS), fuel injection, air bag control, etc.;
  • engines – diesel and petrol, four and two stroke;
  • pumps – centrifugal, water; and
  • turbines – super and turbo chargers, gas and steam turbines.
