I need answer this problem as soon as possible thanks do it correct
01) (12 Points) Consider the loaded rectangular cross section beam shown, the beam length is equal to 4.0 m and the height to width ratio of the cross section is h/b = 4. The distributed load is uniform and has an intensity w=1000 N/m. Assuming the maximum vertical deflection of the beam should not exceed 10 mm. Determine the cross-section dimensions of the beam (b, h). b
