A Segment of a Drive Shaft $\left(d_{2}=200 \mathrm{~mm}, d_{1}=160 \mathrm{~mm}\right)$ Is Sub- Jected to a Torque T = 30 KN

A segment of a drive shaft $\left(d_{2}=200 \mathrm{~mm}, d_{1}=160 \mathrm{~mm}\right)$ is sub- jected to a torque T = 30 kN . m. The allowable shear stress in the shaft
Is 45 MPa. The maximum permissible compressive load P is approxi-
Mately: (A) $200 \mathrm{kN}$
(B) $286 \mathrm{kN}$
(C) $328 \mathrm{kN}$
(D) $442 \mathrm{kN}$
