Question:-
Plane stress at a point in a body is defined by principal stresses 3s ands. The ration of the normal stress to the maximum shear stress of the plane of maximum shear stress is
Option (A)
1
Option (B)
2
Option(C)
3
Option(D)
4
Correct Option:
(B)
Question Solution:
Maximum shear stress (t) = ((s-s) / 2) = s
Normal stress (sn) = ((3s + s) / 2) = 2s
(at maximum shear stress) Now = (sn/t) = 2
