So I can combine the resistance of R1 and R3 to equal Req=2Ω? Alright, I have to go to another class right now but I will sure to post my attempt of a solution by 5pm EST :)
Hm, we have never discussed fixing a ground before. I am not understand how a wire could hold voltage or current if there isn't any element there. Does this mean all of my other calculations are wrong because I didn't account for the properties of the wire?
Hi, I have been at this problem for days and I can't seem to see what I am doing wrong.
Here is the circuit layout along with my work
As you can see I am running into problem getting values of current that do not add up equal to zero. My professor has never discussed how adding a wire like...

Alright guys, I did the whole process but I'm pretty sure I just made a little bump somewhere in my calculations which screwed up my answers.
First I found everything I could find
OA = 350j, so the unit vector...
WOOOOOOOOOOOOOO:oldsurprised: I got the right answer. Wow that was a lot of work, I think I've gone through about 10 pages of paper. :bow:Thank you so much for sticking with me even when it seemed like I couldn't grasp the most simple concepts . Could you help me find the last part to my other...
I know there are infinitely number of vectors perpendicular to bar AC, but I don't know how to find it specifically where bead B is. Thank you so much for your help, I need to figure out these problems within the next hour. :cry:
The answer was positive, hm, anyway I got it right. So for finding the reaction between bead B and rod AC, it would be just the force that is perpendicular to P right? I know the hint says nothing about it but wouldn't the cross product between them?
So the unit vector of BD is (0, -0.6031, 0.7977), then multiplied by the tension is (0, -75.75, 100.2)
The dot product of that and uAC is -3.367 which doesn't seem right...
