Give the expansion of each letter.

Critical stress = Criticl load/Area.

Critical Load as per Euler formula = (pie sq x EI)/L2.

So C.Strees = Pie Sq X E/ (L/r) Sq.

Here R= √i/A.
Radius of gyration.

Radius of gyration r =π(I/A).
I= A*r^2.
Critical load P=(π^2*EI)/l^2.
Both sides division with "A".
P/A = (π^2*EAr^2)/(A*l^2).
P/A = critical stress.
Critical stress= (π^2*E)/(l/r)^2.
