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






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






4. 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.






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






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

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






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






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






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






28. Stored energy or energy at rest.






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






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






31. 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.






32. 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.






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