Intro

Worksheet

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 Aircraft Motion, open the slide entitled Forces in a Climb. Use the information available in the slide 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.
