Ok, so then this problem is unsolvable the way it is asked because it is not possible for there to be enough of an opposing force in the +z direction for the system to have an Fnet of 0? Does that sound right?
Thats part of the problem though. Yes, the -z component would be EA, but remember that EA is part of the whole rope EAD. If this system were at equilibrium and Fnet = 0, then there should be another +z component of equal magnitude, or a combination of +z components. The section AD would have...
If you consider pulley systems in physics that we examine to be massless and frictionless then it wouldn't matter if the pulley rotated or not. The function of the pulley is to redirect the rope and thus redirecting the tension force. This basically does the same thing, doesn't it? The only...
This was a problem on an exam that our professor later discovered was unsolvable THE WAY HE POSED THE QUESTION. First off, it's important to note that this is from a statics class, therefore Fnet = 0 will be true for all problems in our course.
So here's my thoughts on this and I would like to...
