Homework Statement
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?
Homework Equations
alpha = I/T
I = r(alpha)
I = 1/3MR^2
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.
