Static and kinetic friction of rapeseed
Research in Agricultural Engineering, 2007 he present paper examines the static and kinetic coefficient of friction of rapeseed. The project utilized two methods of determination of coefficient of friction of rapeseed: according Eurocode 1 (kinetic) in direct shear test and (static) in model silo.
