Two bars 'X' & 'Y' with same cross-sectional area (A) and length of 'X' is twice of  'Y'. If both bars are of same material and subjected to same axial force, then which of the following will be true?
• A.

Axial spring stiffness (Kx) = Axial spring stiffness (Ky) - Because both have same cross-sectional area 'A'

• B.

Axial spring stiffness (Kx) > Axial spring stiffness (Ky) - Because length 'L' is higher for X then Y

• C.

Axial spring stiffness (Kx) < Axial spring stiffness (Ky) - Because length 'L' is higher for X then Y

• D.

Data is not sufficient
