Outcomes

TEC.LO1(GET)

Apply technological processes and skills ethically and responsibly using appropriate information and communication technologies.

AS9.1.15.

Presents ideas (in a project portfolio) using formal drawing techniques, in two-dimensional or three-dimensional sketches, circuit diagrams or systems diagrams that include all of the following features:
> use of South African conventional drawing standards (e.g.scales, outlines, dimension lines, first and third angle projection);
> notes that clarify design reasoning and key choices;
> impressive enhancements of significant sketches (e.g colour, texture, shade, thick and thin lines, shadow).

TEC.LO2 (GET)

Understand and apply relevant technological knowledge ethically and responsibly.

AS9.2.3

Demonstrates knowledge and understanding of interacting mechanical systems and sub-systems by practical analysis and represents them using systems diagrams:
> gear systems
> belt drive or pulley systems with more than one stage;
> mechanical control mechanisms (e.g ratchet and pawl, cleats;
> pneumatic or hydraulic systems that use restrictors;
> one-way valves;
> systems where mechanical, electrical or pneumatic or hydraulic systems are combined.
