Guide to Propulsion
If so instructed
by your teacher, print out a worksheet page for these problems.
Forces in a Climb - Vectors
Before you begin:
Open the Beginner's
Guide to Propulsion. In the Propulsion
Index under Math Fundamentals, open and study the slide entitled
Vector Components. Then
under Aircraft Motion, open the slide entitled
in a Climb. Use the information available in these slides to help
you complete the activity.
- Using the first
equation: L cos (c) + F sin (c) -D sin (c) - W = ma (vertical)
and the third equation: F -D = Fex , explain and show how
the fourth equation: L cos (c) + Fex sin (c) - W = ma (vertical).
- Using the
second equation and the third equation, explain and show how to obtain
the fourth equation.
- Why isn't
W multiplied by a sine or cosine?
the given diagram, theorems/postulates of geometry, and vectors,
explain each term in the first two equations.
