Strength: refers to the resistance of metal materials to damage (excessive plastic deformation or fracture) under static load. Because the load acts in the form of tension, compression, bending, shear, etc., the strength is also divided into tensile strength, compressive strength, bending strength, shear strength and so on.

As a result, it has been found that shot peening or CBN grinding is more effective for improving both pitting strength and bending fatigue strength than improving the material composition. Therefore, it is evident that residual compressive stress caused by shot peening or CBN grinding suppresses the propagation of cracks. DOI: https://doi ...

Tinting strength. The tinting strength of a colour is determined by the type of pigment, the amount of pigment and the fineness of the grinding. The finer the pigment has been ground, the higher the tinting strength. The higher the tinting strength of a paint, the longer it will conserve its colour by mixing with white.

This effect means that relatively small changes in speed can produce significant increases in force. In the example mentioned, changing from 6,600 rpm to 7,700 rpm multiplies the speed by 1.167. However, the corresponding centrifugal force would multiply by a factor of 1.167 × 1.167, or 1.36. Read: 7 Key Factors in Choosing a Grinding Wheel
