Tribological Systems Design - Lecture 13 - Surface Texture Parameters, Roughness, Hertz Equation

This video explains surface texture parameters such as centre line average Ra, room mean square Rq, Skewness, Kurtosis and Gaussian distribution curve. The video end with the formula for Hertzian contact radius calculation.
