a$.$ Guess which system will have the largest vertical foundation reaction and for which support.

b$.$ List the assumptions you make in order to perform approximate analysis of the frames.

c$.$ Use approximate analysis to find the magnitude and sense of the axial force in the columns and braces for each of the configurations.

d$.$ Determine the approximate reactions for each of the configurations. Verify equilibrium of your results for each configuration.

e$.$ To demonstrate the effectiveness of approximate analysis, use structural analysis software to determine the axial forces in the columns and braces as well as the reactions for each configuration. Assume all members of the frames are made of the same material and section.

f$.$ Submit a printout of the displaced shape for each configuration. On each, identify at least three features that suggest the deflected shape is reasonable.

g$.$ Verify equilibrium of the computer aided analysis results for each configuration.

h$.$ Are the results of your computer aided analysis reasonable? Make a comprehensive argument to justify your answer.

i$.$ Comment on why your guess in part $($a$)$ was or was not close to the solution in part $($d$).$
