1. The problem statement, all variables and given/known data A solid rod of mass M = 2.48 kg and length L = 45 cm is suspended by two strings, each with a length d = 35 cm (see Figure), one at each end of the rod. The string on side B is cut. What is the magnitude of the initial tangential acceleration of end B? The string on side B is retied and now has only half the length of the string on side A. What now is the magnitude of the initial tangential acceleration of end B? 2. Relevant equations alpha = I/T I = r(alpha) I = 1/3MR^2 3. The attempt at a solution I'm completely loss really. When string B is cut and it proceeds to swing down would the length of it's string d be counted into the radius? I don't really know what I'm doing here.
