2) To find the efficiency of a system you
Divide the power out by the power in
Divide power losses by power out
Divide power out (minus losses) by power in
All of the above
None of the above
A.Divide the power out by the power in
B.Divide power losses by power out
C.Divide power out (minus losses) by power in
D.All of the above
E.None of the above
Explanation / Answer
1) Varies with speed change because when more accelerated the gear the are more cycle in the same time and the work increase.(c)
2) Efficency= Power out/ power in
