Find the shear stress in a flange at the junction of hub in rigid flanged coupling if torsional moment is 2980N-m and diameter of hub being 125mm. Also the thickness of flange is 25mm.

(a) 6.77N/mm²

(b) 10.24N/mm²

(c) 4.84N/mm²

(d) 4.22N/mm²

This question stumped me during an online exam.

Question is from the Clamp Coupling & Rigid Flange & Coupling Bushed Pin Flexible Coupling unit in chapter Shafts, Keys and Couplings of Machine Design
