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. Use of the equation PV = a constant - means the numerical result of pressure times volume for a compression or expansion process will






2. Resistance to wear - abrasion and penetration






3. The ratio of the weight of an object being moved along a surface and the force that maintains contact between the object and the surface u = tan(thada) - coefficient of friction is equal to the tangent of friction angle






4. PV=nRT - Boyle's law and Charle's law combined






5. Testing metals and nonmetals of low to medium hardness. uses a ball that is pressed into material and basis calculations on the diameters of ball and indentation.






6. Work done(J)/time(second) - unit of watts - 1 watt = 1 joule/second






7. Refers to the length of the actual path over which a body travels - not concerned with direction - magnitude only
