A mild steel shaft has to transmit 75 kW at 200 rpm. Design a cast Iron flange coupling for the shaft. The allowable stresses are Shear stress for the shaft and keys 40 N/mm²Shear stress for bolts = 28 N/mm²Shear stress for C.I. coupling = 20 N/mm² Take wearing stress as twice the shear stress value and number of bolts for coupling as 6.
Pls give right answer with step by step explanation. Design a clamp coupling for a shaft diameter of 60 mm. The torsional moment to be transmitted by this coupling taking in to account over loading as 160 N-m. The number of bolts used are 6 and the allowable stress in the material of the bolt is limited to 5N / m * m ^ 2 . The coefficient of friction between the shaft and muff material is 0.25.
