Homework Set #1
This homework is based on Chapter 1 of our text book by Anderson. Show all the units
when doing the calculations. Check the final answers to make sure the units make sense.
Do the following problems:
1.1
1.3
1.5 Hint: rotate the supplied force coefficients given on a coordinate system attached to
the chord line to a coordinate system attached to the freestream. See equations 1.18,
1.19 to see how this is done.
1.6 Hint: See example 1.3. You may plot the requested info using Excel or on a graph
paper.
1.9 Hint: See example 1.4 first.
1.12 Hint: Weight = Lift – Buoyancy Force. See example 1.8 to find out how the
buoyancy force is computed.
