Why do machine parts become sticky in winter?
(N/A) In winter,the ambient temperature decreases. As the temperature of the lubricating oil drops,its viscosity increases significantly. This increase in viscosity makes the oil thicker and more resistant to flow,which creates greater internal friction between the moving surfaces of the machine. Consequently,the machine parts do not move easily and appear to become sticky.
