Question (2) A gear drive consists of a 20 -degree steel spur pinion with 20 teeth driving a 60 -tooth cast iron gear. The pinion speed is 3000rpm, face width 30mm and module 4mm and it delivers 10kW power. The gears are to be made to number 6 AGMA quality standards and are to be accurately and rigidly mounted. Use Ka=Ks=Kf=1,Km=1.3,Cp=174(MPa)0.5 and J =0.34404. Determine the AGMA bending stress
