sigma_x, sigma_y and tau_xy are the rectangular stress components of a point. The radius of Mohr's circle is
- A. $\sqrt{sigma_x^2 - sigma_y^2 + tau_xy^2}$
- B. $\sqrt{((sigma_x - sigma_y}$/2)^2 + tau_xy^2)
- C. $\sqrt{sigma_y^2 - sigma_x^2 + tau_xy^2}$
- D. $\sqrt{((sigma_y - sigma_x}$^2)/2 + tau_xy^2)
Answer: B. $\sqrt{((sigma_x - sigma_y}$/2)^2 + tau_xy^2)
Explanation: The radius of Mohr's Circle R = $\sqrt{((sigma_x - sigma_y}$/2)^2 + tau_xy^2).
