Two plates of thicknesses 25mm and 15mm are clamped together by an M8x1.25 bolt used with a regular nut and with regular washers placed on both the nut and bolt head sides. The top plate is 25mm thick with E=70 GPa and the bottom plate is 15mm thick with E=90 GPa Determine the fraction of external load borne by the bolts. The bolt, nut and washer are made up of steel (E=207 GPa). Note: Round up the bolt length to the nearest 5mm
