Need some help in this physics sum

[djsnuk]

mama me sum eka gana kalinuth post ekak damma eth eke MUE tikak waradila dala thiyenne.. Man dan danne harima sum eka.. Puluwannam eka karana hati kiyala deepan... Please machan karana hati thamai dana ganna one...

IN ENGLISH
A stick with a length of a and weight w is placed in a semi spherical vessel with radius a. The
stick forms an angle of TETA to the horizontal line and it is in limiting
equilibrium. Frictional coeficient is MUE and it is less than SQRT 1. What is the
reaction at the bottom pont of the stick?

IN SINHALA
araya "2a" pathrayaka athi bara "w" ha diga "a" dandak tiras thalaya matha theta konayak sadamin semmakaree smathuliththawaye thibe.me hi garshana sangunakaya mue wana athra ehi agaya eke wargamuulayata wada adu agayak ganee...

mehi danda ha pathraya athara prathrikriyawa kopamanada? (yata eka)

i just started ALs.. wait i'll giv a try

 

[Honey-B]

in english da radius is "a".. and in sinhala radius is "2a" machan watz da correct one?

 

[Honey-B]

and machan dont u hav a a sketch of diz sum? i meant how diz stick lies on semi sphere? is it possible for u to giv a sketch also? den it'll b easy
