1. suppose the motor has a bearing shaft diameter of 3.2 cm and the coefficient of friction of each bearing is 0.008. find the torque of friction of bearings.a. 0.0320 N-mb. 0.314 N-mc. 0.411 N-md. 0.481 N-m2. if the motor is running at 3000 rpm and is capable of developing a torque of 120 N-m and is used to drive 3-to-1 reduction gears, what torque is the output shaft from the reduction gears capable of producing?neglect friction losses.a. 13.3 N-mb. 40 N-mc. 120 N-md. 360 N-me. 1080 N-mThanks! 10 points for the best answer...
