Extracted text: Problem 23.4. A hook carries a load of 7.5 kN and the load line is at a distance of 20 mm from the inner edge of the section which is trapezoidal. The load line also passes through the centre of curvature of the hook. The dimensions of the central horizontal trapezoidal section are : inner width = 30 mm ; outer width = 15 mm ; depth = 30 mm. Calculate the maximum and minimum stresses. Also plot the variation of stress across the section. %3D Sol. Given : HE.1000 NT
