The
Lift Equation Problems
If so instructed by your teacher, print out a worksheet page
for these problems.
Open the slide called
The Lift Equation (with
text). Study the labeled diagrams and read the explanation of the lift equation.
- Identify
each letter in the lift equation and list acceptable units for each
quantity.
- Use
Wikipedia
(http://en.wikipedia.org/wiki/Boeing_747),
or a search engine, to find information about
the Boeing 747. What is its wing area?
- If the Boeing 747
above is cruising at 940 km/h, the density of the air is 1.20 g/L, and
the lift coefficient is 1, what is the lift ?
- Use
Wikipedia
(http://en.wikipedia.org/wiki/Boeing_777),
or a search engine, to find information about the
Boeing 777. What is its wing area?
- If the Boeing 777
is cruising at the same velocity under the same conditions as the 747
above, what is its lift?
- Look up the DC-8
on Wikipedia
(http://en.wikipedia.org/wiki/DC-8),
or a search engine.
What is its wing area?
- What is the DC-8's
cruising velocity?
- If the air density
is 1.26 g/L and the lift coefficient is 1.5, what is the lift of the
DC-8?
- Find the F/A-18A
Hornet
on Wikipedia
(http://en.wikipedia.org/wiki/F-18),
or use a search engine.
What is its wing area?
- What is the F/A-18A's
lift while it flies at 700 mph, the air density is 1.31 g/L, and the
lift coefficient is 1.8?
