Question

Cw shear stress in mohr circle is positive or negative

Answer 1

Answer:

with the definition (by Mohr) of positive and negative shear: “Positive shear would cause a clockwise rotation of the infinitesimal element about the element center.” Thus, from the illustration above, σ12 is plotted negative on Mohr's circle, and σ21 is plotted positive on Mohr's circle.
