 ANSWER THE NUMBER 1 AND 2 ONLY. Please, thank you!

1. The design moment capacity of a rectangular beam section is \( 2.72 \mathrm{kN}-\mathrm{m} \). The material's strength is \( 69.12 \mathrm{MPa} \). Design a section of width-to-depth ratio of \( 0.6 \) according to the (1) elastic theory, (2) plastic theory. \( 2 . \) Question: A simply supported floor beam is subject to the loads as shown in Figure. Determine the loading diagrams for load combinations according to ASCE 7-05. Determine also the ultimate design load. 3. Question: For the asymmetric section shown in Figure, determine the plastic moment capacity. The plastic neutral axis (where \( \mathrm{C}=\mathrm{T} \) ) is at \( 20 \mathrm{man} \) above the base. The yield strength is 275 MPa.
