Problem
Suppose a massless string of length l with a point-like mass m attached to its end. We know that the maximum allowed tension in the string is equal to F=mg, where g is the gravitational acceleration. We will attach the string to the ceiling and we hold the mass in the same height with the string straight but unstrained. Then, we will release the mass and it begins to move. Find the angle (with respect to the vertical) for which the string will break.
