The components of stress in a body under plane stress condition, in the absence of body forces is given by

Q. The components of stress in a body under plane stress condition, in the absence of body forces, is given by:

𝜎_𝑥𝑥 = 𝐴𝑥²; 𝜎_𝑦𝑦 = 12𝑥² − 6𝑦² and 𝜎_𝑥𝑦 = 12𝑥𝑦.

The coefficient, A, such that the body is under equilibrium is

Ans: -6.0 to -6.0
