Sectional Modulus

Section modulus calculators the links below on the left are section modulus calculators that will calculate the section area moment of inertia properties of common shapes used for fabricating metal into various shapes such as squares rounds half rounds triangles rectangles trapezoids hexagons octagons and more.

Sectional modulus. Shear modulus of elasticity or modulus of rigidity. Hull girder section modulus is a well accepted parameter measuring the longitudinal bending strength of ships. This modulus is perhaps the single most important design parameter describing hull girder strength.

Section modulus is a geometric property for a given cross section used in the design of beams or flexural members. This allows for optimization of a beam s cross section to resist bending by maximizing a single parameter. Other geometric properties used in design include area for tension and shear radius of gyration for compression and moment of inertia and polar moment of inertia for stiffness.

Also it is the measure of strength of given member. The stress in the outermost section of beam is computed with the help of section modulus. Modulus of elasticity or young s modulus is commonly used for metals and metal alloys and expressed in terms 10 6 lb f in 2 n m 2 or pa.

Using the section modulus the bending stress is calculated as σ b m s. Other geometric properties used in design include area for tension radius of gyration for compression and moment of inertia for stiffness. Hull girder section modulus to the deck often determines the bending strength of the entire hull girder.

Section modulus is a geometric property for a given cross section used in the design of beams or flexural members. Any relationship between these properties is highly dependent on the shape in question. Section modulus it is termed as the ratio of second moment of area and distance from n a neutral axis to the extreme fiber.

G stress strain τ γ. Tensile modulus is often used for plastics and is expressed in terms 10 5 lb f in 2 or gpa. Rather than skimp on the seating opt for sectionals which just take up less room.
