Problem $6-2$: The collar is fixed to the end B of the

rod and serves as a thrust bearing. The other end of

the rod rests on the smooth inclined surface at D$,$

whose outward normal has direction angles

a $=$

b $=$

$60,$ and

g $=45.$ Determine the magnitude of the

reaction force at point D$,$ as well as the components

of the reaction at point B$.$

$($Ans: ND $=130$ lb$,$ Bx $=$ By $=-64\mathrm{.}9$ lb$,$ Bz $=208$ lb$,$

M Bx $=519$ ft$$lb$,$ M By $=130$ ft$$lb$,$ M Bz $=389$ ft$$lb$)$
