Chapter 8, Problem 8.5.10P
The tensional pendulum shown in the figure consists of a horizontal circular disk of a mass M = 60 kg suspended by a vertical steel wire (G = SOGPa) of a length L = 2 m and diameter d = 4 mm.
Calculate the maximum permissible angle of rotation <£m:ls of the disk (that is, the maximum amplitude of torsional vibrations) so that the stresses in the wire do not exceed 100 MPa in tension or 50 MPa in shear.
