Wedge Friction Mechanical Engineering Notes | EduRev

Wedge: A wedge is in general a triangular object which is placed between two objects to either hold them in place or is used to move one relative to the other. For example, the following shows a wedge under a block that is supported by the wall. If the force P is large enough to push the wedge forward, then the block will rise and the following is an appropriate free-body diagram.

Rolling of Metals: Process and Principles (With Diagram)

2021-9-24 · Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. Therefore, the rollers compress the metal while simultaneously shifting it forward because of the friction at the roller-metal interfaces.
