EngineeringQ&A by dot point
A short Q&A bank for every England Engineering syllabus dot point. Each question and answer is drawn directly from our worked dot-point page, so you can scan key concepts before opening the long-form answer.
Engineering design and communication
- Computer-aided design (CAD), computer-aided manufacture (CAM), rapid prototyping and 3D printing, and their advantages and limitations.2Q&A pairs
- Engineering drawing conventions, third-angle orthographic and isometric projection, dimensioning and tolerancing to the relevant standards.2Q&A pairs
- The stages of the design process, the role of the design brief and specification, and how designs are evaluated and improved iteratively.2Q&A pairs
- The impact of modern technologies on industry, employment, society and the environment, including automation, sustainability and the product life cycle.2Q&A pairs
Engineering manufacture
- Heat treatments (hardening, tempering, annealing, normalising) that change a metal's properties and surface treatments and finishes that protect or improve a surface.2Q&A pairs
- Permanent joining methods (welding, brazing, soldering, adhesives, riveting) and temporary methods (nuts and bolts, screws), and when each is used.2Q&A pairs
- Quality control checks, tolerance and how upper and lower limits are stated, and the measuring and gauging equipment used to check parts.2Q&A pairs
- Scales of production (one-off, batch, mass and continuous) and how the quantity affects the process, cost, tooling and automation used.2Q&A pairs
- Wasting processes that remove material (cutting, drilling, turning, milling) and shaping processes that form material (casting, moulding, forging), with their uses.2Q&A pairs
Engineering materials
- Ferrous metals (contain iron) and non-ferrous metals, common examples and their properties, and why alloys are used to improve a base metal.2Q&A pairs
- The main categories of engineering material (metals, polymers, ceramics, composites) and the mechanical, physical and aesthetic properties used to describe and compare them.2Q&A pairs
- Thermoplastics and thermosetting polymers, their properties and uses, and how composites combine materials to give a better performance than either part alone.2Q&A pairs
- Selecting a material by matching its properties to the product requirements, while balancing cost, availability, sustainability and aesthetics.3Q&A pairs
- Smart materials that change a property in response to a stimulus, and modern materials developed through new processing, with examples and uses.2Q&A pairs
Maths and science for engineers
- Units and prefixes, rearranging formulae, ratio and proportion, areas and volumes, and using standard form for engineering calculations.2Q&A pairs
- Ohm's law, electrical power, series and parallel resistance, and using the correct units in electrical calculations.2Q&A pairs
- Forces, moments and the principle of moments, mechanical advantage and velocity ratio, and efficiency in simple machines.2Q&A pairs
Systems
- Input, process and output components in electronic systems (sensors, resistors, transistors, logic, LEDs, motors, buzzers) and how they are combined.2Q&A pairs
- The input-process-output model, the role of feedback in a control system, and how systems are drawn as block diagrams.2Q&A pairs
- The four types of motion, mechanisms that change motion (levers, linkages, gears, pulleys, cams, cranks) and how they alter direction, speed and force.2Q&A pairs
- Programmable components (microcontrollers), how flowcharts represent control programs, and the advantages of programmable control over fixed wiring.2Q&A pairs
