A shоrt steel I-beаm [E = 200 GPа] hаs a length оf L = 3.00 m, depth оf 315 mm, flange width of 139 mm, and moment of inertia of Ix = 88.5 × 106 mm4. The beam rests on a hard rubber elastic foundation whose spring constant is k0 = 0.270 N/mm3. If the beam is subjected to a concentrated load P = 270 kN at its center, determine the value of β.
