The centre to centre distance between two consecutive rivets in a row, is called
A. Margin
B. Pitch
C. Back pitch
D. Diagonal pitch
frame of the question is not correct.
Most logical answer is friction decreases.
Simply due to the fact that decrease in friction will cause slip of belt ergo reduction in power transmitted.
Answer is D, not C
C is correct, practically speed increases than slip increases and so power decrease.
How c????
it should be D
