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.

2. Ways of overcoming difficulties






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






4. Provides a framework for design and problem solving work






5. A bar or rod that tilts on a pivot - or fulcrum - used to overcome a resistance or to raise a weight when force is applied is a

7. The amount of effort needed to raise a load by using a pulley system is determined by






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






9. The force applied to a lever






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






11. The English unit of measuring work






12. A guide to help make problem solving in technology more effective






13. A lever in which the fulcrum is between the effort and the load






14. More than one pulley working together






15. 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






16. Work divided by time






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

24. The ability to do work






25. An inclined plane which is wrapped around a cylinder






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






27. Two gear wheels that intermesh in the same plane - regulating the speed or force of motion and reversing its direction

42. A wheel fixed to a support with a rope that is run over the wheel to change the direction of a force applied to the rope






43. A system of pulleys that consists of one rope wound around two separate sets of pulley - each of which is free to rotate independently on the same axle
