I am really bad with the whole tension force thing.
A rope with a breaking strength of 291 N supports a 470 N weight suspended from the middle of the rope. What is the minimum angle the rope can make with the horizontal without breaking?
Help would be greatly appreciated!

First, since the object is pulled by the rope in two directions, each side of the rope pulls half of the weight = 235N.
so if we say that the angle is the one formed by the rope and the horizontal,
sin angle = 235/291
= 0.8076
so angle = 53.9 degrees

sturdy on you for submitting the criticism, be certain you persevere along with your weapons. What a wanker! no less than he will recieve a warning, regrettably on account which you have positioned up with it for see you later you need to maintain working with him till he does it returned yet i do no longer think of he gets extra desirable than one warning. If it quite is severe sufficient then he gets a right now dismissal which it sounds to me like he could, as long as you do no longer artwork in a boys club. you will basically could wait and spot, i'm useful the HR branch can help understand what action they have taken. in case you're no longer happy with it then touch your ombudsman or proper government branch and document a criticism with them.
