A cast iron component $($as shown in the figure below$)$ is required to be cast by sand

casting. The flask dimensions is $320320200m{m}^3.$ Density of cast iron $=7\mathrm{.}16$

$\frac{g}{c}{m}^3.$ The density of sand is $1\mathrm{.}65\frac{g}{c}{m}^3$

Calculate the metallostatic force and the weight needed to prevent the generated

buoyancy force from lifting up the upper flask. $($Assume that the parting line is

located $25$ mm above the base of the pattern shown in the figure below$).$
