Final TWO$-$TWO$-$F

$($Spring Quarter$)$

PROBLEM $4$

Determine if the frame is determinate, unstable, or redundant $($indeterminate$)$ for the configuration shown, then complete the following;

If the frame is unstable, draw$/$describe the instability AND show a solution for stabilizing the frame. Neatly sketch the reconfigured frame and its support and connection types.

If the frame is redundant $/$ indeterminate, state how many "unknowns" need to be "released" AND draw a solution for "releasing" the unknowns in order to create a stable and determinate frame. Neatly sketch the reconfigured frame and its support and connection types.

If the frame is stable, show how you determined the condition.
