Fig. $3$

The $33$ mm diameter solid steel shaft shown in Fig. $3$ of $\text{'}\text{'}$Torsion Assignment Figures'$\text{'}$ has a shear modulus of G$=77$GPa$.$ The shaft is subjected to torques T$1=92$ Nm$,$ T$2=17$ Nm and T$3=39$ Nm$.$Determine the angle of twist of end B relative to end A$.$ The answer should be given in degrees correct to two decimal places with sign convention according to the right hand rule.

The $33$ mm diameter solid steel shaft shown in Fig. $3$ of $\text{'}\text{'}$Torsion Assignment Figures'$\text{'}$ has a shear modulus of G$=66$GPa$.$ The shaft is subjected to torques T$1=98$ Nm$,$ T$2=20$ Nm and T$3=42$ Nm$.$Determine the maximum shear stress in the shaft at point A$.$ The answer should be provided in MPa correct to two decimal places.
