Machine parts are jammed in winter. Why?

Text Solution

Verified by Experts

A lubricating oil is generally used between the various parts of a machine to reduce the friction. In winter, since the temperature is low, the viscosity of oil between the machine parts increases considerably, resulting in jamming of the machine parts.
