    Find the resistance of a resistor using Ohm's Law?

    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 :)

    Find the resistance of a resistor using Ohm's Law?

    Thank god for photoshop. I am not sure what you meant by switching around vs? I hope I drew this correctly.

    Find the resistance of a resistor using Ohm's Law?

    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?

    Find the resistance of a resistor using Ohm's Law?

    I thought I already found the voltage of V2 to be 4V? I am not quite sure how that specific element is responsible for the voltage of the wire?

    Find the resistance of a resistor using Ohm's Law?

    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...

    Statics - Moment using both vector and scalar approaches

    Omg, all I didn't do what convert to N * m, :blushing: I'm dumb. Check your units boys and girls.

    Statics - Moment using both vector and scalar approaches

    Homework Statement Homework Equations Mo=Fd Mo=r x F The Attempt at a Solution 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...

    Maximum weight a bar and cables can hold before breaking

    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...

    Maximum weight a bar and cables can hold before breaking

    And from there force equations I found FOA to be -0.6983W

    Maximum weight a bar and cables can hold before breaking

    Alright I found FAB to be (4615/5539)W and FAC to be (3000/5539)W

    Maximum weight a bar and cables can hold before breaking

    So I am finding all the forces from the moments first then applying those to the force equations?

    Engineering statics equilibrium problem

    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:

    Engineering statics equilibrium problem

    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?

    Engineering statics equilibrium problem

    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...

    Maximum weight a bar and cables can hold before breaking

    ΣFx = -FAB(28.8) - FAC(44.31) + W(48) ΣFy = FAB(9) + FAC(13.85) - W(15) ΣFz = FAB(12) - FAC(18.46)
