This site will be used for file storage…

Friday, September 3rd, 2010

I will keep this edublog for file storage as it is simple to upload files. I refuse to pay $40 per year so I can simply domain map from my $7.99 /year godaddy domain. Google blogger is blocked by MCPS content filters, but it allows FREE domain mapping. My domain www.craigmesserman.info is not filtered, and redirects now to my Blogger blog. Edit: now my google site, which is not blocked. Still: Neener, neener, IT nazis! <thumbs nose> I refuse to take a Moodle class too! </unthumb>

Air Pressure / Airbag questions

Monday, July 19th, 2010

1. If an airbag lifts 100 lbs. under a surface area of 10 in2, what is the pressure in the bag?

2. What are the things that cause air pressure to decrease? [in the atmosphere, I assume.]

3. How do you find pressure? [how do you calculate it?]

4. Does the surface area of the air bag depend on how much pressure has to be used to lift the table?

5. How much weight can a 250 square inch airbag lift using an air compressor that delivers 90 psi?

Jet Stream:

6. Give specific examples to explain how the jet stream was discovered.
7. Describe one example of how the jet stream has been used by people.
8. Describe the consequences of the movement of the jet stream to the north.

Pressure Blocks:
9. Does air of the same weight but different volume have the same pressure? Explain.
10. How does higher density affect air pressure?
11. If an aircraft flies into a colder area, does the aircraft travel up or down? (By the pilot maintaining a constant pressure altitude)
12. What do the red and blue boxes represent?
13. Do all the boxes exert the same downward pressure?
14. What type of air has more pressure?
15. What gives more lift, warm or cold air?
16. How can the red box (volume of air) have the same air pressure as the blue box?
17. The blue boxes represent _________ air and the red boxes represent __________ air.

aircraft weight and balance

Wednesday, July 14th, 2010

Read this: http://www.pilotfriend.com/training/flight_training/wt_bal.htm

-I can describe the purpose of aircraft weight and balance.

-I can calculate the weight and balance of a Cessna 172 with various loads.

-I can properly balance (and record balance data) for my indoor RBP airplane.

Foilsim Lab

Monday, July 12th, 2010

Basic learning targets:

I can describe the basic forces involved in flight.
I can describe the structure and function of airplane components (wing, in this case).

I can test five variables for their effect on the lift of an airfoil, and explain those variables and their effects.

Your write up must include graphs of the results for each variable, along with a description of each graph (analysis) and an explanation of each graph (conclusion).

2. Why is the conclusion the most important part to the scientific method?

3. What is the formula to find force?

4. What equals 1 Newton?

5. What are the 7 steps of a lab writeup?

6. Explain how the amount of area affects drag.

7. What is the relationship between surface area and drag?

8. What exactly is drag?

9.Why does drag affect an object?

10. What does air resistance have that causes drag?

11. What does F = ma stand for?

12. Explain drag.

13. Do larger objects have more or less drag?

14. Define drag.

15. What is the difference between drag and area?

16. How does the area affect the drag?

17. What is the acceleration of a car that travels from 35 m/s to 100 m/s?

18. Define drag.

19. What creates more drag, total area or profile area?

20. What is the order of the scientific method?

21. Based on your results for max. drag, does any dimension of your object help determine the drag?

22. Does the length of the string attached to your object help determine drag?

23. When something has a smaller area, how does it affect the drag?

24. How would the drag change if you made your total areas the same but profile areas different?
