A shоrt steel I-beаm [E = 200 GPа] hаs a length оf L = 2.50 m, depth оf 290 mm, flange width of 144 mm, and moment of inertia of Ix = 96.5 × 106 mm4. The beam rests on a hard rubber elastic foundation whose spring constant is k0 = 0.280 N/mm3. If the beam is subjected to a concentrated load P = 240 kN at its center, determine the maximum deflection. The value of β is 0.8501 /m.
