Ok. I am hoping that some of you have the same book that I do which seems to be the standard for SnD classes. IT is “Vector Mechanics for Engineers” 5th ed. Beer/Johnston.
Its gonna be hard to explain my question unless you can look at the diagram yourself, so please refer to the diagram on problem 3.45, pg 85. It should be an L shaped pipe suspended by a single cable thru a ring.
My question is “How do I solve for the tension in the cable with the downward force P given”. The force at the corner. For instance, if the force P was given as 1000N, or any force for that matter, how do I translate that into the tension in the cable? I don’t need a solution, I just want a method because I need to be able to do this.
If it is a rigid body, which it is, does that mean that I can move the force P to any point in the rigide body and retain all of the same characteristics? For some reason I am thinking that the tension in the cable is = P. I say this because the force is only in one direction. If I am not right, which I suspect I am not, then do I have to solve for the components of the force on the pieces of cable on each side of the rings and then add them?
I am doing this class independent study and don’t have a way to check my method until I meet with my instructor which isnt for a week. This is holding me back from solving other pieces of the problem.
BTW, I know the cable tension is given in the problem, but I need to know how to solve for the situation that I gave you, so disregard the cable tension that is given.
Thanks for your help.
