Question

Q17. When a body is subjected to a direct tensile
stress (0) in one plane accompanied by a
simple shear stress (Txy), the minimum normal stress
is
(A) (0,/2) + (1/2)* (0,2 + 4 T2x)
(B) (0,/2) - (1/2)* 10,2 + 4 T?xy)
(C) (0/2) + (1/2) 0,2 - 4 T?xy)
(D) (1/2) * 10x2 + 4 TZ,y)​

Answer 1

Answer:

option b

Step-by-step explanation:

(σx/2) - (1/2) × √(σx² + 4 τ²xy)
