A square hollow section (SHS) is to be used to fabricate building frames. The SHS measures 128 mm in width (in the x direction) x 128 mm in height (in the y direction) and has a wall thickness of 6 mm. Given that the allowable tensile stress due to bending must not exceed 130 N mm-2, determine the internal moment resistance (IMR) of the SHS in units of N m to the nearest N m referenced to the x-x axis, but do not enter the unit in your answer. Hint: to calculate the moment of inertia of the SHS, find the moment of inertia of the "solid" square and subtract from this the moment of inertia for the "hollow" square
