GCSE AQA Design Technology Revision Guide: Technical Principles, Forces, and Scales
Scales of Production and Sustainability in Design Technology
This section of the GCSE AQA DT knowledge organiser covers the four main scales of production and introduces sustainability concepts in design technology.
The guide explains the following scales of production in design technology GCSE AQA:
- One-Off Production: Creating a single, unique product, often for specific client needs.
- Batch Production: Producing more than one unit at a time in sets or batches.
- Mass Production: Manufacturing large volumes of products in highly automated factories.
- Continuous Production: Running production lines non-stop to meet constant demand.
For each scale of production, the guide provides product examples, advantages, and disadvantages, helping students understand when each method is most appropriate.
Example: One-off production is suitable for items like the queen's crown, wedding bands, and bespoke furniture.
Vocabulary: Batch production refers to making products in sets or batches, commonly used in bakeries and furniture manufacturing.
The guide then introduces the concept of sustainability through the Six Rs:
- Refuse
- Rethink
- Reduce
- Reuse
- Repair
- Recycle
Definition: Carbon footprint is the amount of carbon dioxide released into the atmosphere as a result of the actions of an individual, organisation, or community.
This comprehensive overview of production scales and sustainability principles provides students with essential knowledge for their GCSE design and Technology curriculum, enabling them to make informed decisions about manufacturing processes and environmental impact in their design projects.
Forces and Stresses in Design Technology
This section of the GCSE AQA Design and Technology guide focuses on the fundamental concepts of forces and stresses in design. It explains the difference between static and dynamic loads and introduces the formula for force calculation.
The guide then delves into five main types of forces:
- Tension: Force that stretches or pulls an object.
- Compression: Force that squeezes or compacts an object.
- Torsion: Force that twists or distorts an object.
- Bending: Force that deforms or changes the shape of an object.
- Shearing: Force that deforms or splits an object.
Each force type is accompanied by real-world examples to help students understand their applications in everyday objects and structures.
Example: Tension can be observed in a car tow, helicopter propellers, and pull-down machines in gyms.
The guide also covers techniques for improving functionality in design, including:
- Folding (e.g., corrugated cardboard)
- Bending (e.g., curved structure of tubes)
- Strengthening and enhancing (e.g., adding ribs, gussets, or fillets)
- Reinforcing (e.g., metal frameworks in reinforced concrete)
- Webbing (e.g., seatbelts and parachutes)
- Lamination (bonding layers of materials)
- Fabric interfacing (adding rigidity to textiles)
Highlight: Understanding these forces and reinforcement techniques is crucial for students to design and create functional, durable products in their GCSE design and technology coursework.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
