Answer:

Maximum shear stress = 15 kN.

Explanation:

Given,

  • Tensile stress acting on the body = T = 20\ kN/m^2
  • Compressive stress acting on the body = T = 10\ kN/m^2

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 = \tau

\Rightarrow \tau = \dfrac{T\ -\ C}{2}\\\Rightarrow \tau\ = \dfrac{20\ -\ (-10)}{2}\\\Rightarrow \tau\ =\ 15\ kN.

Hence the shear stress acting on the body due to the tensile and compressive stresses is 15 kN.
