1. Write a computer code to calculate the forces in members BE and BC for an arbitrary uniform load \( \omega_{\circ} \mathrm{lb} / \mathrm{ft} \). Write a code for random input for the given application. 2. Use the computer code to calculate the explicit values of the forces in members \( \mathrm{BE} \) and \( \mathrm{BC} \) for a horizontal wind load of 800 lbs, given that a separate analysis shows that \( 5 / 8 \) of this force is transmitted to the center connection at \( C \) and the rest is equally divided between \( D \) and \( \mathrm{B} \). 3. Model using SkyCiv or SAP2000 for code verification. 4. Understanding that the steel ( \( E=29000 \) psi) truss is to be designed to support the design loads in the most economical and cost saving way by using the smallest weight of steel possible, given that a. \( 18 \mathrm{lbs} / \mathrm{in}^{2} \), is the allowable stress for the steel b. the specific weight of the steel used is \( 0.6 \mathrm{lb} / \mathrm{in}^{3} \) c. cost for the steel is \( \$ 255 \) per pound 5. Please keep in mind that the scale and application of your design determines the size. 6. The total weight of the steel, and thus its cost, must be as small as possible. - Show the force magnitudes and whether tension or compression. - Show that with the truss areas, all stresses are at or below allowable.
