    - Mohr's circle method is a graphical method used to determine principal stresses, normal, tangential and resultant stresses.

    - Direct stress (σ) is represented on X-axis and shear stress (τ) is represented on Y-axis in Mohr's circle.

    - Centre of this circle can be determined by using the formula: C = (σx – σy) / 2

    - The radius of Mohr's circle is determined by using the formula: R = √ [(σx – σy) / 2]2 + τ2
