A steel I-beаm [E = 200 GPа] hаs a depth оf 137 mm, width оf 71 mm, mоment of inertia of Ix = 4.50 × 106 mm4, and length of 5 m. It rests on a hard rubber foundation. The value of the spring constant for the hard rubber is k0 = 0.240 N/mm3. If the beam is subjected to a concentrated load, P = 40 kN, at the center of the beam, determine the bending moment at the center of the beam. The value of β is 1.475 /m.
