Technical Design And Engineering

Subject : engineering
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. Processes and knowledge that can be used to extend human abilities as well as satisfy human needs and wants.






2. A specialized processor that resides directly on the motherboard of a computer. It can be thought as the brain of a computer. It processes the data; also referred to as a microprocessor or a 'computer within the computer.'






3. A language - used to write computer programs - that can easily be translated into machine language.






4. The use of simple machines to multiply the output force of a mechanical system.






5. The judgement of the end result based upon given criteria.






6. The formal rules that guide the design process.






7. A unit that collects waves and decodes information contained within those waves.






8. The passage of electric current through an electrolytic fluid for the purpose of separating molecules.






9. The design of equipment and environments to promote human health - safety - and well- being; sometimes referred to as ergonomics.






10. The act of breaking a particular subject into different parts to achieve clarity of understanding.






11. The unlawful acquisition of some one's personal information for use without their consent.






12. The comparison of the amount of goods produced (output) to the amount of resources (input) that produced them






13. The number of waves that pass through a given point in one second. It is commonly measured in a unit called hertz. 1Hz is equal to one complete wave cycle in one second.






14. A wave created by electric and magnetic fields;it travels through the air like ripples in a pool of water.






15. The capacity to do work or exert effort.






16. The amount of resistance the power system must overcome or - alternatively - the amount of force output by the power system: also can be referred to as weight or pressure.






17. The field of knowledge relating to materials as they exists on a molecular or atomic level.






18. The basic framework of a system






19. The use of a computer system to produce technical drawings and/or design a product.






20. The capacity to do work or exert effort.






21. The law that states that if the pressure of a gas increases - the volume decreases (provided that the temperature remains constant).


22. Current flow in which electrons reverse direction at regular intervals.






23. A device that creates a mechanical advantage. Complex machines are based on 6 simple machines in various combinations.






24. The effect of a system's processes and/or output on the systems environment. this effect can be either positive - negative - or in some cases both.






25. Any information about the output of a system that is returned to the system for the purpose of determining whether or not the system is functioning as it should.






26. The height of a wave measured from the top of its peak to the bottom of its trough. It is an indicator of the strength of a wave.






27. A method of obtaining energy from waste products






28. Creating things through the process of planning.






29. The money a business makes after all expenses have been paid






30. Someone who starts a business.






31. Heat generated within the Earth as the result of the decay of radioactive materials beneath the Earth's crust.






32. The combination of knowledge of science - mathematics - technology - and communication to solve technology problems.






33. A group of parts that work together to accomplish a goal. The basic parts of a system are input - process - and output.






34. A device capable of detecting (sensing) changes in its environment; light and movement are examples.






35. A production process in which the part or product moves down a line from one station to the next while parts are added.






36. The technology field focused on sending messages and other in formation using different means.






37. The process of creating the most effective and functional product or process while meeting all the criteria and constraints.






38. The long term storage mechanism of a computer. It holds the computer programs used for word processing - playing games - and other tasks.






39. A very small solid state panel that contains light sensitive photo- sites or photo- diodes. The CCD uses the photo- sites to convert light into electrical signals transformed into an image.






40. Stored energy or energy at rest.






41. An activity in which two or more people try to think of as many possible solutions to a problem as they can. Ideas are not evaluated or criticized at this time.






42. The use of 3D CAD drawings to create real models of a product within a sort of time.






43. The path by which electric current or pulses flow.






44. A production system in which products are made one at a time according to customer's specifications.






45. Current flow in which electrons move in only one direction.






46. A group of people working together to accomplish a common goal.






47. The use of pressurized liquid or gasses to control and transmit power.






48. A resource that is entered into a system.






49. A production system in which a limited quantity of a part or product is made. After the production run - the machines are retooled or changed over to accommodate the production of a different part or product.






50. The act of putting different things together to form a new product or idea.
