What is difference between shearing stress and crushing stress?

Answer 1

Differentiate between shearing and crushing.

Answer 2

Tension stress tends to pull a material apart and acts normal to its cross section plane.

Shear stress tends to shear a material apart and acts in the plane of its cross section plane.

Crushing stress tends to push a material and acts normal to its cross section plane, in the opposite direction of tension. Crushing stresses are compressive stresses and could also be bearing stresses.

For a material laoded in pure tension, shear exists at 45 degrees along the cross section plane and is 1/2 the tensile value. For pure shear, tension exists 45 degrees along the cross section plane and is equal to the shear value.

Most all metals are stronger in tension than in shear, by a factor of about 1.7.

Some materials, like chalk or concrete, are stronger in shear than in tension. If loaded in shear, they will break intension 45 degrees along the cross section

Answer 3

Shear stress acts tangent to a plane, and it is represented by the greek letter "tau". The yield stress represents the lever in which metal behave elastically.

Answer 4

Shear stress tends to slide the material particles while crushing stress compresses the material. For most metals, shear strength is about 60% of compression strength.
