Question

Chapter 15, Problem 048 A rectangular block, with face lengths a = 34.0 cm and b = 40.0 cm, is to be suspended on a thin horizontal rod running through a narrow hole in the block. The block is then to be set swinging about the rod like a pendulum, through small angles so that it is in SHM. The figure shows one possible position of the hole, at distance r from the block's center, along a line connecting the center with a corner. (a) For what value of r does the minimum the period of the pendulum occur? There is actually a line of points around the block's center for which the period of swinging has the same minimum value. (b) What shape does that line make? (a) Number Units Click if you would like to Show Work for this question:
