True/False
Indicate whether the sentence or statement is true
or false.
|
|
| 7. | Error
can enter this lab in the adjustment of the ramp height.
|
|
| 8. | Error
can enter this lab in the reading of the spring scale.
|
|
| 9. | Error
can enter this lab by incorrectly plotting data on the graph.
|
|
| 10. | Error
can enter this lab if the spring scale is not zeroed before data collection.
|
|
| 11. | ED =
the height of the ramp.
|
|
| 12. | RD =
the length of the ramp.
|
|
| 13. | The
weight of the object (Load) is referred to as the FA.
|
|
| 14. | The
reading on the spring scale is referred to as the LP.
|
|
| 15. | The
graphed data should, if correctly plotted, fall along a straight line.
|
|
| 16. | Mechanical advantage multiplies your effort.
|
|
| 17. | The
best mechanical advantages occur at the highest RD measurments.
|
|
| 18. | The
worst mechanical advantages occur at the lowest RD measurements.
|
|
| 19. | An
architect building a wheel chair access ramp should strive for a mechanical advantage of between 12
and 15.
|
|
| 20. | Lifting an object straight up would yield a mechanical advantage of 1.
|
|
| 21. | Mechanical advantages of 2-10 yield a ramp that is too steep.
|
|
| 22. | The
advantage to a great inclined plane is that you can move a very heavy object UP to a higher level
with relatively little effort.
