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 σ - τ plane is 1 MPa, the Mohr’s circle representation of the state-of-stress is given by

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