PROBLEM 2 (20 pts) For the truss given: 1) Calculate the DSI (2pts) 2) Compute the reaction at the roller C (18pts) (Suggestion: use the roller reaction at \( \mathrm{C} \) as redundant, then see problem \#1) Assume each bar has a cross-sectional area of \( 10 \mathrm{in}^{2}, \mathrm{E}=30 \times 10^{3} \mathrm{ksi} \)
