Mohr Stress Circle When an Element is Subjected To Normal Stress Only

Mohr Stress Circle When an Element is Subjected To Normal Stress Only

For drawing mohr stress circle,the normal stresses are represented along x-axis and shear stresses along y-axis. The Mohr stress circle is drawn, as shown in figure,with its center at a distance of (𝞼1𝞼)/2 and radius equal to  (𝞼𝞼)/2 . 
Mohr Circle
Where 𝞼1  & 𝞼 are the major and minor principal stresses respectively .A point M on this circle,subtending an angle 2α at the center C, will represent the stresses on the plane which was making an angle α with the major principle plane .

In other words the co-ordinates of this point would be equal to shear stress (𝞃 )and normal stress (𝞼)
