A rectangular footing for a utility shed is to be placed above point A and will be uniformly loaded. The pressure on the soil will be $150k\frac{N}{m^2}($q$).$ A $4m$ diameter treatment tank exists. The pressure on the soil from the treatment tank is $250k\frac{N}{m^2}.$ The soil at point A can withstand a maximum stress increase of $60k\frac{N}{m^2}.$ Assume the proposed shed is constructed rapidly. Are the structures safe? $($Will the soil at point A resist failure?$)$
