Part A

Replace the loading acting on the beam $($Figure $1)$ by a single resultant force. Suppose that $\backslash ($ F$\_\{1\}=450\backslash$mathrm$\{$~N$\}\backslash ),\backslash ($ F$\_\{2\}=300\backslash$mathrm$\{$~N$\}\backslash ),$ and $\backslash ($ F$\_\{3\}=700\backslash$mathrm$\{$~N$\}\backslash ).$

Determine the magnitude of the resultant force.

Express your answer to three significant figures and include the appropriate units.
