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. 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.






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






3. A method of obtaining energy from waste products






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






5. Trade of products and services on a global scale.






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






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






8. Creating things through the process of planning.






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






10. 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.






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






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






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






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






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






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






17. 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.






18. The basic framework of a system






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






20. The use of computers in each stage of the design process.






21. A series of operations that includes all of the activities that must be performed in order for the system to yield the expected result.






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






23. 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.






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






25. 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.






26. A circuit in which electricity flows along more than one path.






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






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






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






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






31. The formal rules that guide the design process.






32. A device that orbits the Earth and receives messages from one location and transmits them to another.






33. Someone who starts a business.






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






35. The use of force to act on an object in order to move move the object in the same direction as the force.






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






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






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






39. The imitation - as closely as possible - of the real- life circumstances in which a solution is intended to be used.






40. A resource that is entered into a system.






41. 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.






42. The use of lasers to record realistic images of three- dimensional objects.






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






44. A popular movement.






45. The capacity to do work or exert effort.






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






47. The path by which a message travels from the sender to receiver.






48. 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.






49. 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.'






50. Restriction or limit placed on a product.
