a person wants to hang a picture which weighs 5 newtons from a nail. the string she has only supports a maximun tension of 2.5 newtons. if she ties both ends of the string to the picture and then loops the middle of the string over the nail in the manner indicated in the illustration to the right will the string break? why or why not? somebody guide me throught this please?

    I don't have the picture but I imagine it's something like: |dw:1328827682188:dw| Therefore, if the picture was in equilibrium, you should calculate T and check whether it's an admissible value for your string!

    Okay so, Weight of the portrait(in newtons)=5 Newtons. Maximum capacity of string=2.5 Newtons. Since the girl has looped it in such a way, we must note that THE STRING HAS DOUBLED. So when the string is doubled, the weight of 5 Newtons gets equally divided between both the parts, so the weight carried by each string in the loop would be: 5/2=2.5N which is the maximum capacity, as a result the string will NOT break :)
