Structures and Forces
The force that pulls objects toward the Earth
What is “Gravity”?
This step involves creating physical or digital versions of your design.
What is prototyping?
This type of software is commonly used for 3D modelling
What is “CAD” or “Computer-Aided Design”?
A circuit has a resistance of 10 ohms and a current of 2 A. What is the voltage?
What is 20 V?
The names of all of the senior engineering teachers at Mansfield SHS

This triangular structure is commonly used for stability in structures such as bridges
What is a truss?
Brainstorming should be judgment-free
True
This tool checks whether a surface is perfectly horizontal or vertical (full name required)
What is a spirit level (or bubble level)?
A rectangular block has dimensions 4 cm × 5 cm × 2 cm. What is its volume?
What is 40 cm³?
The senior engineering teacher who was not born in Australia
Mr Duong (New Zealand)
The internal force that resists the sliding of one part of a structure past another.
What is shear force?
The first phase of the QCAA engineering design process
What is the explore phase?
What does CNC stand for in manufacturing?
What is “Computer Numerical Control”?
If a gear has 20 teeth and meshes with another gear with 40 teeth, what is the gear ratio?
1:2 (or 2:1)
The senior engineering teacher who had a previous career as a boilermaker
Mr Romero
The term for a force that causes an object to dynamically rotate around a pivot point
What is torque (moments are static)?
Engineers use this document to communicate the final version of a product
What is “Technical drawing” or “Blueprint”?
This measuring tool is used to accurately find the distance of a smallish objects
What is a vernier caliper?
If a 4:1 pulley system is lifting a 40 kg object, how much force is needed (ignore friction)?
What is 100 N?
(Explanation: Weight = 40 × 9.8 = 392 N → 392 ÷ 4 ≈ 98 N)
The first year that any QCAA Engineering syllabus was used in QLD schools
What is 2019?
The shape of the bending moment diagram for a simply supported beam with a uniform distributed load
What is a parabolic curve (in beam theory)?
This inventor created over 1,000 patents, including the first electrical illumination device
Who is “Thomas Edison”?
This type of 3D printer uses melted plastic to build objects layer by layer
What is Fused Deposition Modelling (FDM)?
A truss has 5 joints and 7 members. Is it statically determinate? Use the formula m = 2j – 3.
Yes
(m = 7, 2j – 3 = 7 → 7 = 7)
In the 2025 QCAA Engineering syllabus, the ISMG descriptor that isn't "symbolising and communicating" or "determining and generating".
What is Synthesising and Evaluating?
