Hinge Connection Design: A Reference Code

This document summarizes the design of a hinge connection. It calculates that the connection requires 2 M12 Grade 8.8 bolts to safely carry the tensile and shear forces of 21.8 kN and 21.6 kN respectively. It also analyzes the plate size and thickness of 270 mm by 170 mm and 12 mm thick and verifies that it can withstand the shear and moment stresses. All components are determined to have acceptable stress levels below their yield capacities.
