Cylinder wall effect
Web(1) High spots on the cylinder wall caused by mechanical and thermal distortion. (2) High temperature of the cylinder-wall, which burns off the oil film. (3) Piston-rings that do not give uniform wall pressure or give excessive wall pressure. (4) High-spots on the piston that create high pressures and dry up sections of the cylinder- wall. WebAs the name implies, shear stress refers to the action of a force applied to a material, as indicated by equation 1. 𝞽 = F/A (1) where 𝞽 is the shear stress, F is the applied force, and A is the cross-sectional area parallel to the direction of the applied force. The above equation gives the average shear stress per unit area.
