Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Designing in a way that takes account of the environmental impact of the product throughout its life






2. The application of scientific information concerning the relationship of human beings to the design of objects - systems and environments






3. The costs that must be paid out before production starts - for example machinery. these costs do not change with the level of productions






4. Long- term aims and objectives of a company and ways of achieving them by allocation of resources






5. Pleasure derived from people's mental and emotional reactions to a product.

12. A conscious act either to ensure a continuing market or to ensure that safety factors and new technologies can be incorporated into later versions of the product






13. Lack of essential vitamins and minerals resulting from unbalanced food intake and specific problems of food absorption






14. The use of computers to aid manufacturing






15. Apply technologies to improve the building environment and functionality for occupants and tenants while controlling costs to improve end- user security - comfort and accessibility and help user productivity






16. Technology appropriate to the context in which it is applied. appropriate technologies are low in capital cost - use local material wherever possible - create jobs using local skills and labour - involve decentralized renewable energy sources - make






17. This is the factor in which the machines multiplies the force put into it






18. A measure of how fast heat is conducted through a slab of material with a given temperature difference across the slab.






19. A product development process obtained through 3D - parametric and associative CAD systems. The main feature of this new method is that the design originates as a concept and gradually evolves into a complete product consisting of components and sub-
