Problem:

$($of $24)$

Do not round intermediate answers. Give your final answer$($s$)$ to three decimal places. Check your units.

A force $F$ is applied to a corner of a rectangular cube as shown. The force has a magnitude of $1377$ N and makes angles of

$83,$ and $50$ with the $x,$ and $y$ axes respectively. Determine:

$($a$)$ the magnitude of the moment of $F$ about axis $OA,$

$($b$)$ the components of the moment $($of the vector$)$ of $F$ about axis $OA.$

Hint: You first need to find the angle that $F$ makes with the $z$ axis.

$M(OA)=,N-m$

$M(OA)x=,N-m$

$M(OA)y=,N-m$

$M(OA)z=,N-m$
