What is the objective of coning of wheels?
Coning of wheels helps the outer wheel to travel a longer distance than inner wheel. Explanation: When the locomotive travels a curve centrifugal force acts on it. Due to this the outer wheel moves outwards and has to travel longer distance as compared to the inner wheel. Thus coning of wheels is done.
