Introduction To Engineering - 7

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.

12. Provides a structure for thinking and doing






13. A pulley that makes work easier






14. A shaft with a screw thread that meshes with a toothed wheel to alter the direction of motion - and change the speed and force






15. If you generate alternative solutions and begin to build your best solution - but you have problems building your design - what should you do?






16. Seeks to explain and describe the physical world






17. When generating ideas for a solution to a problem - it is important to do which of the following in order to effectively and visually communicate these ideas for use in construction drawings?

23. A force that opposes motion






24. Energy of position






25. The turning point of a lever






26. More than one pulley working together






27. Two wheels that intermest at an angle to change the direction of rotation - also altering speed and force if necessary

29. The generation of ideas for solutions






30. An inclined plane which is wrapped around a cylinder






31. Work divided by time






32. Energy may change form but the amount of energy remains the same






33. A pulley that changes direction of effort but provides no mechanical advantage






34. A fixed wheel with a rope or chain that is attached to a load - used to change the direction of a force or to lift heavy objects - is a

39. Involves the effort you put in and the distance over which you maintain the effort






40. The force applied to a lever






41. A wheel that meshes with a sliding toothed bar - converting rotary motion to reciprocating (to- and- fro)






42. Levers in which the fulcrum is always placed between the effort and the load are called






43. A bar or rod that tilts on a pivot - or fulcrum
