Let's consider a solid circular shaft subjected to the torque loads as shown. Determine the minimum required diameter "D" if the shaft is made of a material having a shear modulus \( G=50 \mathrm{GPa} \), so that the maximum angle of twist at its end will not exceed \( -0.024^{\circ} \) (calculated according to the positive sign convention).
