sir, i am very doubtful regarding a question as to how to take sections while deriving the center of mass of various bodies..?
ex: while considering hollow hemisphere we take section mentioning or varying with theta(angle made with either horizontal or vertical) but when it is the case with the solid hemisphere..we take the section to be varying with the height alone...or varying with the verticle distance..plz ...tell me the way how and where to apply these???
