Please answer this Civil engineering question asap, will definitely give a thumbs up. Thanks in advance.

### Engineering Structural Analysis Exercises #### 1. Retaining Wall Reinforcement - **Task:** On the retaining wall illustration, draw the wall and footing reinforcing steel in the correct locations. - **Diagram Description:** The diagram shows a vertical and horizontal section of a retaining wall. Reinforcement needs to be added for structural integrity. #### 2. Seismic Base Shear Force Distribution - **Task:** For the illustrated 3-wall building, calculate and indicate the force on each wall during a lateral seismic event. The seismic base shear is given as 20 kips in each direction. - **Diagram Description:** The outline of a building is shown with dimensions 60’-0” in length and 20'-0" in width. There are two long walls and one short wall with the roof line indicated. #### 3. Beam Deflection Analysis - **Task:** Determine a 50 KSI beam needed to achieve a similar deflection as a W18x35 (36 KSI) beam, which deflects 3/4” under a load with a span of 20’-0”. - **Concept Explanation:** This requires calculating the deflection of a beam under load and comparing different steel strengths to maintain the same deflection. #### 4. Roof Framing Illustration - **Task:** Show the framing on the roof for the depicted house. - **Diagram Description:** A roof plan is shown from above with indications for prefabricated trusses, post and beam, and stick-framed sections. It’s an L-shaped layout. These exercises provide practical applications for structural engineering principles such as material mechanics, seismic analysis, and construction planning.
