Sentences with phrase «viscous coupling»
"viscous coupling" refers to a device that helps distribute power between two connected components (like wheels in a car). It uses a thick fluid (viscous) to transfer the power and can adjust the amount of power each component receives based on the amount of resistance or slip. This helps improve traction and stability in vehicles, especially in slippery conditions. Full definition
