asked Sep 22, 2022 in Machine Dynamics by Grayson (34.3k points)

What is the effect of variation of pressure on the rails?

(a) Hammering action

(b) Piston effort

(c) Variation in tractive force

(d) Swaying couple

I have been asked this question by my college professor while I was bunking the class.

Enquiry is from Effect of Partial Balancing of Reciprocating Parts of Two Cylinder Locomotives in section Balancing of Reciprocating Masses of Machine Dynamics

Correct option is (a) Hammering action

The best explanation: The effect of an unbalanced primary force perpendicular to the line of stroke is to produce variation in pressure on the rails, which results in hammering action on the rails.
