WebFeb 24, 2024 · Normally, rolling friction inhibits the movement (speed v →) of the system. However, since the force is pointing in the "backward" direction, it looks like it is increasing the speed of the wheel. Therefore, it should accelerate the system. This seems unintuitive to me. Can someone please clarify this contradiction? Thanks! Update: WebNov 23, 2024 · The effects of roll geometry, friction coefficient and rolling temperature on the surface wrinkle defect were analyzed utilizing the orthogonal test method.
