Required informotion For the Pratt bridge truss and loading shown, determine the average normal stress in member CE, knowing that the cross-sectional area of that member is 5 in 2 . Take \( P=75 \) kips, \( Q=95 \mathrm{kps}, \mathrm{r}=13 \mathrm{ft} \) and \( \mathrm{s}=9 \mathrm{ft} \) Using the FBDiequilibrium equations of the entire truss, (a) The vertical reaction at \( \mathrm{A} \) is \( \mathrm{A}_{\mathrm{y}} \) " (b) The verticai reaction at H is Hym (kip)
