A gear box with an overall gear ratio of 6 to 1 has a torque of 35 N m applied to the input shaft. What will be the torque on the output shaft if the gear box is 90% effcient?

The output shaft of a reduction gear rotates at one-eighth the speed of the input shaft. What will be the effciency if the output torque is 40 N m when the input torque is 6 N m?
