Consider a bar element of a square hollow cross-section of area31.65mm² and length 1,894mm. If both the cross-sectional area andlength increases 9-fold (i.e. by 9 times) each, then by how manytimes will the stiffness constant of this element increase? Note:round-off your answer to the nearest integer
