QUESTION 2: Torsional moments of \( 3 \mathrm{M} \) and \( \mathrm{M} \) intensity are applied to the compound bar made of two different materials (core steel and plated copper). Shear modulus for steel and copper are \( \mathrm{G}=80 \mathrm{GPa}, \mathrm{Ga}=30 \mathrm{GPa} \), shear safety stresses (Tem) \( 80 \mathrm{MPa} \), (Tem) \( 50 \mathrm{MPa} \). Find the torsional moment Mb that the system can safely carry and calculate the total angle of rotation (CA) in the bar (30p).
