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 basic framework of a system






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






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






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






5. Stored energy or energy at rest.






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






7. 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.






8. 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.






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






10. Restriction or limit placed on a product.






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






12. Studying the effects of a given technology to determine its impact.






13. Standards that a product must meet to be accepted.






14. The capacity to do work or exert effort.






15. The superimposition of sine waves on electromagnetic carrier waves.






16. An agreement that permits free trade among member nations. The decrease in trade barriers help manufacturers find larger markets for there product.






17. 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.






18. The measure of work done over a period of time as energy is converted from one form to another or transferred from one place to another.






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






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






21. The formal rules that guide the design process.






22. A resource that is entered into a system.






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






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






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






26. 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.






27. A popular movement.






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






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






30. Someone who starts a business.






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






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






33. The process of turning abstractions of thought into concrete ideas.






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






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






36. The splitting of the nucleus of an atom.






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






38. 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.'






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






40. 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.






41. 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.






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


43. A method of obtaining energy from waste products






44. 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.






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






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






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






48. Creating things through the process of planning.






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






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