Answer:
Maximum shear stress = 15 kN.
Explanation:
Given,
- Tensile stress acting on the body = T =
- Compressive stress acting on the body = T =
As we know that the tensile and compressive stresses are opposite in nature, therefore the sign of these stresses should be opposite.
Therefore from the maximum shear stress,
Maximum shear stress =
Hence the shear stress acting on the body due to the tensile and compressive stresses is 15 kN.
