Two Flanged Shafts Are Connected by Eight 18-Mm Bolts $T_{0}$ Is Approximately: (A)

Two flanged shafts are connected by eight 18-mm bolts. The diam- eter of the bolt circle is 240 mm. The allowable shear stress in the bolts is
90 MPa. Ignore friction between the flange plates. The maximum value of
Torque $T_{0}$ is approximately: (A) $19 \mathrm{kN} \cdot \mathrm{m}$
(B) $22 \mathrm{kN} \cdot \mathrm{m}$
(C) $29 \mathrm{kN} \cdot \mathrm{m}$
(D) $37 \mathrm{kN} \cdot \mathrm{m}$
