please answer question 1 & 2

1) Minimum Beam Depths [ 5 points] Using Table 2.5.2.6.3-1, provide the minimum depths for a 120 simply supported span of the following superstructure types: i. Overall depth of composite steel I-beam [1 point] ii. Steel truss [ 1 point] iii. Precast prestressed I-beam [ 1 point] iv. Prestressed adjacent box beam [ 1 point] v. Reinforced concrete box beam [ 1 point] 2) Steel beam proportions [ 10 points] For the beam below, verify the flanges and webs meet the AASHTO proportion requirements (assume the webs are NOT longitudinally stiffened). If any of the proportion requirements fail, determine what dimensions would need to be adjusted, and adjust the plate sizes so the beam is satisfactory
