Problem $1.$

A steel rod is connected to the corner of a

building at an angle of $60$ in the $x-y$ plane and

is supported by two cables having magnitudes

of $F_1=240N$ and $F_2=450N$

a$)$ Write vec$(F_1)$ as a Cartesian vector

b$)$ Write vec$(F_2)$ as a Cartesian vector

c$)$ Determine the resultant force of vec$(F_1)$

and vec$(F_2).$ Report its magnitude and

coordinate direction angles.
