Problem4 - An annular brass plate ( G=39GPa ), of thickness t=6mm, is used to connect the brass shaft AB, of length L_(1)=50mm and radius r_(1)=30mm, to the brass tube CD, of length L_(2)=125mm, inner radius r_(2)=75mm, and thickness r=3mm. Knowing that a 2.8kN*m torque T is applied to end A of shaft AB and that end D of tube CD is fixed, determine (a) the maximum shearing stress in the shaft-plate-tube system, (b) the angle through which end A rotates.
