Find the classification of the given soil using unified soil classification system and give the group symbols and group names.

Question

14.1 A beam of rectangular cross section is 125 mm wide and 200 mm deep. If the maximum bending moment is 28.5 kN⚫m, determine (a) the maximum tensile and compressive bending stress, and (b) the bending stress 25 mm from the top of the section. 14.2 A rectangular beam 50 mm wide and 100 mm deep is subjected to bending. What bending moment will cause a maximum bending stress of 137.9 MN/m² (MPa)? 14.3 Determine the bending moment in a rectangular beam 3 in. wide and 6 in. deep if the maximum bend- ing stress is 15,000 psi.
