5. Under normal operating conditions, a torque of $2.4\mathrm{kN}.\mathrm{m}$ is applied to the electric motor in the figure below. Since the shear modulus of the shaft material is $G=85000\mathrm{kN}/{\mathrm{cm}}^2$ and each shaft is solid, find the torsion angle (PAD) formed in the shafts between pulley $D$ and motor $A$.
