An I-beam is made of steel (E = 200 GPa) and is 5.0 m long (Figure P5.90). It has cross-section properties Ix = 24.0 × 106 mm4, Iy = 1.55 × 106 mm4, depth = 203.2 mm, flange width = 101.6 mm, and area = 3490 mm2. The helical support spring has a constant k = 1.00 MN/m. For the case where Q = 30.0 kN, determine the force in the spring and the maximum bending stress in the beam.
