Web20 Feb 2024 · The area moment of inertia, also called the second moment of area, is a parameter that defines how much resistance a shape (like the cross-section of a beam), has to bending because of its geometry. Consider a thin plank that supports a 100 kg load. The plank will be much less stiff when the load is placed on the longer edge of the cross-section. WebThe shear stress at any given point y 1 along the height of the cross section is calculated by: where I c = b·h 3/12 is the centroidal moment of inertia of the cross section. The maximum shear stress occurs at the neutral axis of the beam and is calculated by: where A = b·h is the area of the cross section. baie mahault plageWebA hollow cylindrical shaft has an internal diameter of 54 mm and a wall thickness of 4.7 mm.
