The input torque on the shaft is 200 pound-feet and the output torque is 760 pound-feet. what’s the torque ratio? a. 3: 1 b. 4: 1 c. 3.8: 1 d. 3.3: 1

C.

Step-by-step explanation:

We know that the torque ratio is the ratio of its output torque to its input torque.

Given : Input torque :

Output torque :

Then , the torque ratio is given by :-

Therefore, the torque ratio = 3.8 :1

its definatley   this on your answer choice?

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
