Below is a Floor Girder with dimensions as shown. The system carries a dead load $$\mathrm{wd}=1.2?\mathrm{kN}/\mathrm{m}$$, distributed live load $$\mathrm{wL}=4.2\mathrm{kN}/\mathrm{m}$$ and a concentrated load $$PL=$$ $$60\mathrm{kN}$$. Based on this information, answer the following questions: Question 1.1: Construct the influence line for the moment at $$D$$ in the girder. Points earned will depend on neatness, accuracy and showing values at all critical locations. UPLOAD your diagram. Question 1.2: Construct the influence line for the shear in PANEL CD in the girder. Points earned will depend on neatness, accuracy, and showing values at all critical locations. UPLOAD your diagram Based on this information, answer the following questions: Question 1.3: What is the maximum positive moment at D? [Enter the value in $$\mathrm{kN}$$ and meter in appropriate combination] Based on this information, answer the following questions: Question 1.4: What is the maximum negative moment at $$\mathrm{D}$$ ? [Enter the value in $$\mathrm{kN}$$ and meter in appropriate combination] Based on this information, answer the following questions: Question 1.5: What is the maximum positive shear at the panel $$CD$$ in the girder? [Enter the value in $$\mathrm{kN}$$ and meter in appropriate combination] Based on this information, answer the following questions: Question 1.6: What is the maximum negative shear at the panel CD in the girder? [Enter value in $$\mathrm{kN}$$ and meter in appropriate combination]
