I having figuring out a problem gave me, but he won't tell me how to do it. Here's the problem "A small bead with mass M is attached to a very light string hung from a ceiling. The string can be torn by a force exceeding the value of 10 Mg where g is the acceleration due to gravity. The bead on the string may ocsillate harmonically with a period To. A student decides to perform another experiment. He takes the attached bead aside from its equilibrium and pushes it in such a way that the beaad performs a full revolution in a horizontal plane. What is the time of one revolution of the bead that can be calculated with teh data, given above? Is this time a maximum or minimum value of all possible?" I've looked all over the internet and text books trying to find examples with no success. I know that I need the period etc but I don't know how to apply them to getting the answer. Thanks for the help.
