1. The problem statement, all variables and given/known data A body of large mass is suspended by means of a string A from the ceiling, and another similar string B is attached to the bottom of the body. Which string would break when string B is pulled (a) sharply, and (b) steadily? Why? 2. Relevant equations F=ma 3. The attempt at a solution I assume string B would break first. I'm not sure why. On string A, I've labelled T with an arrow going one way, and one going the opposite way on the string. This seems vaguely familiar to me. I've drawn an arrow from the large down labelled g. Unfortunately, I'm not very good at this sort of thing, but I want to become a pro.
