Aerospace Engineering > GATE 2026 > Stress Transformation
The state of stress at a point in a 2-D body, in the x-y Cartesian coordinate system, is represented in matrix form as [σ]. The transformation matrix [Q] rotates the coordinate system to a new x'-y' Cartesian coordinate system. Select the CORRECT option(s) that represent(s) the state of stress in the new coordinate system.
A
[Q] [σ] [Q]T
B
[Q] [σ] [Q]−1
C
([Q]−1)T [σ] [Q]T
D
[Q]−1 [σ] [Q]

Correct : a,c
