Question

Which of the following is true regarding chain drives?

(a) The chain drives may be used when the distance between the shafts is less

(b) The production cost of chains is relatively low

(c) The chain drive needs low maintenance

(d) The chain drive has no velocity fluctuations

The question was posed to me by my college professor while I was bunking the class.

Origin of the question is Chain Drives in division Belt, Rope and Chain Drives of Machine Kinematics

Answer 1

The correct choice is (b) The production cost of chains is relatively low

To elaborate: The chain drives may be used when the distance between the shafts is less. This is an advantage of using a chain drive over belt or rope drives.
