What is the Mohr's circle equation for the centre?
centre = x + y / 2
What is the Mohr's circle equation for Raidus / Tao max
raidus or Tao max = sqrt((x-centre)^2 + Tao xy^2)
What is the Mohr's circle equation for principle stresses?
stress1 = centre + radius (on right side)
stress2 = centre - radius (on left side)
What is the Mohr's circle equation for theta?
2theta = tan^-1(Tao xy / (stressx - centre))
- rearrange for theta
- draw new diagram of box and stresses
What is the Mohr's circle equation for max shear stress? (T)
2alpha = 90 - 2theta
- rearrange for alpha
