Machines, mechanisms and hydraulic systems, and the calculation of their performance.
These are the statements the Engineering Studies syllabus makes about Lifting and Load-Shifting Machines. Dux records each one against the questions you answer, so you can see which of them you have actually been tested on and which have never been asked.
Levers, pulleys, gears and linkages, and mechanical advantage.
Ideal versus actual advantage, and where the losses go.
Pascal's principle, pressure, and force multiplication through area.
Sling angles, load charts and the stability of a lifting operation.
Motor selection, torque–speed characteristics and drive matching.
Guarding, interlocks and control systems, and the hierarchy of controls.
HSC Engineering Studies - Written Paper Shape is 100 marks in 180 minutes. Questions on Lifting and Load-Shifting Machines are not one shape repeated: the command word decides what the marker is looking for, and the mark value decides how much of it. These are the ones Engineering Studies uses.
Dux writes practice for this module in exactly these shapes, so the drill is the same task the paper sets — not a general knowledge quiz with the module name on it.
Lifting and Load-Shifting Machines is module 4 of 4 in Engineering Studies. Students routinely lose marks because a question spans two modules, so the neighbouring modules are worth reading next to this one.
Dux diagnoses Engineering Studies dot point by dot point, then writes questions in the shape this course marks. Written answers come back marked against the bands.
