Beginner's Guide to Propulsion
Forces in a Climb - Vectors

Activity

If so instructed by your teacher, print out a worksheet page for these problems.

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 Forces in a Climb. Use the information available in these slides to help you complete the activity.


  1. 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 to obtain
    the fourth equation: L cos (c) + Fex sin (c) - W = ma (vertical).




  2.  Using the second equation and the third equation, explain and show how to obtain the fourth equation.




  3.  Why isn't W multiplied by a sine or cosine?




  4. Using the given diagram, theorems/postulates of geometry, and vectors, explain each term in the first two equations.
