The hemisphere of radius a has centre of mass at 3/2a, 1/6 a as shown in the diagram. How do I find the angle between PC and horizontal when the hemisphere is in equilibrium with its curved surface on ground?

The equilibrium condition is equivalent to minimum energy condition and that means that the ordinate of center of mass must be the lowest possibile, so that the angle between PC and horizontal [in radians] must be...
Kind regards
can you please draw a picture of this? I am having some trouble imagining it.(Wondering)Quote:

The equilibrium condition is also the 'minimum energy' condition and it is realized when the center of mass is at the minimum possible quote. The value ofI have indicated minimizes the quote of the center of mass, that means that for any other value of
