25 Questions

1. ICE generates electricity for electric battery -Electric motor turns wheels

2. Compression of fuel mix

3. Piston travels up and exhaust valve opens. Combustion by product exhaustion

4. A fluid power system uses hydraulics and a fluid under pressure to create a greater force than is applied

5. Rotation will not occur - but translation might occur

6. Allows comparison between different measuring systems and units - Necessary to market internationally

7. When the work done by the effort exceeds the work done by the load - the load...

8. Modern Technology- More efficient-Better Cooling-Easier to service- longer life - lither weight- More expensive

9. A combination of components

10. Piston travels up and both plugs are closed

11. If a force causes rotations -Vector- Machines can have more than one torque-Units: foot- pound and newton - meter - i.e. engines - airplanes - propeller

12. Liquid or gas

13. When the sum of all forces and the sum of all moments both equal forces - No movement

14. Are independent of other dimensions - They are limited in number - length - mass - time - temperature - force

15. If the force needed to operate the machine (input force) is less than the force being opposed or the load being moved (output force) -The ratio of the output force divided by the input force -If the number is greater than one - there is a mechanical

16. Length x Width x Height

17. Dimensions and units

18. Derived from - or composed of - base dimensions i.e. Area (length x width) - Weight (mass x acceleration) - velocity (length/time)

19. Combustion ignited by spark plug and materials are compressed

20. One that pushes on an object

21. Three- dimensional property measured in units of length times length times length =length x width x height

22. What we are studying

23. The branch of science and engineering involving measurement

24. (pi) x (radius)^2

25. More compact (size of beer keg) - No valves -Benefits: fewer parts - lower engine weight Problems: seal - lower inertia forces -1 rotar=3 to 4 pistons
