The cup and the arms of an of an anemometer are fabricated from a material of density p. Knowing that the mass moment of inertia of a thin hemispherical shell of mass m and thickness t with respect its centroidal axis GG' is 5ma2/12, determine the mass moment of inertia of the anemometer with respect to the axis AA'. (a) the ratio of a to I for which the centroidal moment of inertia of the cups is equal to 1 percent of the moment of inertia of the cups with respect to the axis AA'.
