Determine the components of reaction at the ball and
socket joint A and the tension in each cable necessary
for equilibrium of the rod.
Damn, I just finished Statics.
Thank you!
I'm getting different answer for reaction at A?

What are Ax ,Ay and Az and where do they come from 😢
Whenever dealing with a ball-in-socket problem, you must deal with the momentum of the ball moving at that point. So at point A you simply add a moment measurement for Ax, Ay, and Az.
Damn, no offense but you seriously overcomplicated this problem. It's much easier if you immediately recognize that the tension in the cables must be equal. This makes sense because there are no external forces in the y-direction, the x & z lengths of the cables are the same, and the y-component of the direction of each tension force is opposite (they *must* perfectly cancel each other out). From there, you can immediately and directly solve for both tensions in one step by taking the sum of moments about the y-axis. This can be done without going through cross-product hell too, as only the z-components of the tension forces create a moment about the y-axis (the other components are along it or intersect it), and we already know how far B is from A (M=Fd).
he is reading this off chegg or something. If you look at his other video you notice he "teaches" it differently almost everytime
@@Notorious224 yeah i can tell, some solutions are good but this one is aweful lol
I like it because my prof always wants us to use cross product
