Question

The stress state at a point in a material under plane stress condition is equi-biaxial tension with a magnitude of 10 MPa. If one unit on the $\sigma -\tau$ plane is 1 MPa, the Mohr's circle representation of the state-of-stress is given by

• A. a circle with a radius of 10 units on the $\alpha -\tau$ plane
• B. a circle with a radius equal to principal stress and its center at the origin of the $\sigma -\tau$ plane
• C. a point on the $\tau$ axis at a distance of 10 units from the origin
• D. a point on the $\sigma$ axis at a distance of 10 units from the origin

Answer 1

The correct option is D a point on the $\sigma$ axis at a distance of 10 units from the origin

Given ${\sigma }_1=100,{\sigma }_2=10MPa$
