If 8 bolts are emplaced in a clamp coupling with shaft diameter 80mm d, calculate the diameter of each bolt if coefficient of friction is 0.3 and torque transmitted is 4000N-m. Permissible tensile stress is 80N/mm².
(a) 27mm
(b) 25mm
(c) 23mm
(d) 21mm
The question was asked in a scholarship test.
I found this question in the Clamp Coupling & Rigid Flange & Coupling Bushed Pin Flexible Coupling concept in part Shafts, Keys and Couplings of Machine Design
