Let load P be moved to one end of the beam in Problem 10.7. Determine the maximum deflection and maximum flexural stress in the beam and give the location of the maximum flexural stress.

Problem 10.7

A steel I-beam (E = 200 GPa) has a depth of 127 mm, width of 76 mm, moment of inertia of Ix = 5.12 × 106 mm4 and length of 4 m. It rests on a hard rubber foundation. The value of the spring constant for the hard rubber is k0 = 0.270 N/mm3. If the beam is subjected to a concentrated load, P = 60.0 kN, at the center of the beam, determine the maximum deflection and maximum flexural stress at the center of the beam.
