- 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...

Just so you know they didn't get us a sub and we aren't in s10 today

ReplyDeleteI wasn't here yesterday and didn't get the packet so could you post it so I can print it out
:7(
DeleteRemember only the verification requires the actual force tables!!!!!!

ReplyDeleteEnjoy!
When are we gonna have the test Tuesday or Thursday for next week ??

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?
ReplyDeleteNo. 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...
