Problem $5.$

$($L$.$O$.1\mathrm{.}1\mathrm{.}4$; $1\mathrm{.}2\mathrm{.}2\mathrm{.}2)$

$($Hibbeler$,2015)$

Describe the force in Figure $3$ in Cartesian vector notation $($CVN$),$ magnitude and unit vector $(F,$hat$()),$ the magnitude and coordinate direction angles $(F,{}_x,{}_y,{}_z)$ or $(F,,,),$ and the magnitude and transverse and azimuth angels $(F,,).$

Hint: The definition of a unit vector from the coordinate direction angles can be used to solve for a third coordinate direction angle if the other two angles are known.

Problem $6.($L$.$O$.1\mathrm{.}1\mathrm{.}4)$

$($Hibbeler$,2015)$

Determine and express the resultant force in Cartesian vector notation $($CVN$),$ magnitude and unit vector $(F,$hat$()),$ the magnitude and coordinate direction angles $(F,{}_x,{}_y,{}_z)$ or $(F,,,),$ and the magnitude and transverse and azimuth angels $(F,,)$ and sketch this vector on the coordinate system.
