PROBLEM $3$A

Describe ALL the load paths $($LP$)$ of a downward force at POINT $\text{'}$X$\text{'}$ shown above using the member labels.

PROBLEM $3$ B $($Extra Credit$)$

Ignore the load at point $x$ and you only have a $5,000lb$ point load acting down at point $Y.$ The capacity of the columns are $2600lb\frac{s}{e}$ach. Which columns will fail?

PROBLEM $4$

What are the forces in the members: Column A$,$ Brace B$,$ and Beam C$?$ Hint: The beam force, $FC,$ is $0$ kips because the Brace $B$ is much stiffer than Beam $C$ in taking a lateral force as its connected directly into the foundation.
