Part B

Part complete

As shown, three forces, F$1$

$,$ F$2$

$,$ and F$3$

$,$ act at the same point on an object. $($Figure $2)$ The point of application is the origin of a Cartesian coordinate system. F$1$

$,$ which has a magnitude of F$1$

$=20\mathrm{.}0$ kN

$,$ is in the y$$z plane and is described by an angle $\backslash$beta $1$

$=35\mathrm{.}0$ degrees

$.$ F$2$

is in the x$$z plane and is described by integer lengths of a similar right triangle; its magnitude is F$2$

$=18\mathrm{.}5$ kN

$.$ If the sum of the forces is equal to zero, what is the magnitude of F$3$

$?$

Express your answer numerically in kilonewtons to three significant figures.
