Part A

Determine the force in member $\backslash ($ B A $\backslash )$ of the truss and state if the member is in tension or compression. Set $\backslash ($ P$\_\{1\}=890\backslash$mathrm$\{$lb$\}\backslash )$ and $\backslash ($ P$\_\{2\}=425\backslash$mathrm$\{$lb$\}\backslash ).($Figure $1)$

Express your answer to three significant figures and include the appropriate units. Assume positive scalars for members in tension and negative scalars for members in compression.

Part B

Determine the force in member $\backslash ($ B C $\backslash )$ of the truss and state if the member is in tension or compression.

Express your answer to three significant figures and include the appropriate units. Assume positive scalars for members in tension and negative scalars for members in compression.

Part C

Determine the force in member $\backslash ($ C A $\backslash )$ of the truss and state if the member is in tension or compression.
