FTL


  • Calculate the equilibriant force for each case 1-4
  • Do this both graphically and algebraically.

Note:  For some cases you get to choose one of the other forces.
Vector diagrams should be drawn to scale labeled and color coridinated.
You will need a protractor!  Or maybe not if you figure out another way to draw your vectors head to tail.
Here is a video on one method of translation

This is a method.   Ilf you discuss with your team you may come up with a better way to do it.  Think to previous labs.

FORCE TABLE ARE ONLY REQUIRED TO CHECK THE RESULTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  •  Check your results using the force table lab to attain equilibrium.  (If you are in class)
  • Calculate the % error for the magnitude of your equilibriant.
  • Report the absolute error for the angle.

Why would it be meaningless to calculate % error for your angle?  Think back to the first step in solving these problems...

  5. If we change the angles from 20 and 80 to 0 and 60 should we just make a note that the zero is at 20 degrees or is there a special way to show it?

  6. No. The frame of reference was given in the lab. Which yields a result that is only valid in that frame of reference. This also insures that all will get the same answer...
