Problem 1: Analyze and compare the two trusses shown below. For each truss determine:
a. All bar forces, indicate tension or compression
b. The required cross sectional areas for bar, given an allowable tensile stress of 45 ksi, and an allowable compressive stress of 24 ksi.
c. Tabulate your result showing bar forces, cross sectional areas and lengths
d. Calculate the total weight of each truss and determine which truss has a more efficient configuration. Explain your results.
e. What other conclusions can you draw from the study?
