Introduces learners to cemented aggregate mixtures including important elements such as: aggregate properties; concrete mix design methods; hot mix asphalt mixes; inspection and testing concepts; field quality control and verification testing methods; safety during material sampling; material sampling procedures; and use of random sampling.
Introduces the basics of soil mechanics including: understanding the origins, properties and characteristics of different soils; using multiple systems to classify soils; soil compaction, and the relationship between moisture and density; stresses in soils (such as point loads, and uniformly distributed loads); and different methods of subsurface soil exploration (including probing, boring, and drilling).
Analyze advanced concepts of direct and alternating current (DC & AC) and expand the knowledge of electrical circuitry. Various equipment will be studied that converts AC to DC and also that inverts DC to AC. The effects of varying frequency on AC filter circuits will be explored through labs. The usage of various voltage regulators will be also be covered. IET 5 expands on concepts learned in IET 1, IET 2, and IET 3 and will continue to be expanded upon in IET 6.
Introduces the microcontroller, a tiny computer which uses digital inputs and outputs to control electrical/electronic circuits. A Basic Stamp microcontroller will be programmed via a USB port to a PC using a PBASIC editor program. It will then be connected to digital inputs such as switches and sensors and used to control output circuits such as LED displays, DC motors, relays, buzzers and servo motors.
Develops the principles of electrical fabrication. Emphasis will be given to the practical application of interpreting engineering drawings, wiring machine components and troubleshooting electrical panels.
