The coupling of two rods with a tensile load of 80 kN is realized by flanges which are connected by 4 screws. All screws are oriented in the direction of the tensile load. Which screw core diameter must be at least present if the allowable tension stress is 32N/mm2? Enter the result of the screw core diameter in millimeter. Round solution to one decimal place. Enter the minimal possible ISO metric screw thread according to DIN 13-1 (Column 1, First Choice) / ISO 262 (Column 1, First Choice): (Mxx) Give your answer in the following format: screw core diameter, ISO metric screw thread. Example: if the screw core diameter is 12,3mm and the ISO metric screw thread is M12 then use 12.3, 12 as answer value.
AI image description
Perspective photo of a metallic bolted flange coupling joining two coaxial cylindrical, hollow-ended rods or tubes. Two facing circular flanges are clamped together by circumferential hex-head bolts and nuts; a thin dark seam separates the flange faces. A red arrow extends axially outward from the open left tube toward the lower left, and another red arrow extends outward from the right tube toward the upper right, indicating opposite axial pulling directions. Small 'schwer fittings' marking appears below the left tube.
