1. A section of commercial shafting, 2 m long between bearings, carries a 1000N pulley at its midpoint, as shown in Fig. The pulley is keyed to the shaft and receives 30 kW at 150 rev/min that is transmitted to a flexible coupling just outside the right bearing. The belt drive is horizontal and the sum of the belt tensions is 8000 N. Assume Kt = Kb = 1.5. Calculate the necessary shaft diameter The allowable shear stress for the shaft is 40 MN/m². (Ans: 94.8 mm) 1000 1000

10. A simply supported shaft between bearings camies a steady load of 10 kN at the centre. The length of shaft between bearings is 450 mm. Neglecting the effect of stress concentration, find the minimum diameter of shaft. Given that Endurance limit = 600 MPa; surface finish factor = 0.87; size factor = 0.85; and factor of safety = 1.6. [Ans. 35 mm]
I want right solution plz solve if you know 100% flange coupling connects two 50 mm diameter lengths of commercial shafting. The coupling flanges are bolted together with four bolts of the same material as the shaft. The bolts are set in clearance holes. The diameter of the bolt circle is 240 mm and the flange thickness is 22 mm, Determine the minimum bolt diameter required to transmit the same torque that the shaft can transmit. What power may be transmitted at 200 rev/ min under steady load conditions?
