PROBLEM $2(5$ points$)$: A bar whose length is $6$ m has its center of gravity $2$ m from one end. It slides inside a smooth hemispherical

tank of radius r$=4$m$.$ The bar has a weight of W$=150$N$.$

EN $1\mathrm{.}2$

Calculate the angle theta which the bar makes with the horizontal when equilibrium is attained.

Calculate the reaction at B$,$ in N$.$

Calculate the reaction at A$,$ in N$.$
