What is the best cross section resisting torsion loads?

In general, the torsional performance of closed cross-sections is superior to that for open cross-sections. Circular closed shapes, such as round HSS and steel pipe, are most efficient for resisting torsional loading.

Which is the most efficient cross section resisting bending moment?

1. Circular cross-sections have higher resistance to bending moment and deflection than rectangular cross-sections.

Which of the following steel sections is most ideal for resisting torsion?

Note: Box sections are best for resisting torsion.

Which section is good for bending?

I – section is best suited for transverse loads I- section can take bending load as well as shear load. It can take up to 80\% of bending load which is resisted by flanges and 90 \% of shear load is resisted by web.

Which of the following section is the most efficient in carrying moment?

Forces act perpendicular to the center of gravity. Hence your most eficient section has the most force in the farthest section regarding the center of gravity.

What is the strongest cross section?

equilateral triangle
The strongest column has an equilateral triangle as cross section, and it is tapered along its length, being thickest in the middle and thinnest at its ends. Its buckling load is 61.2\% larger than that of a circular cylinder.

Which is the most efficient section shape for bending?

The most efficient shape for both directions in 2D is a box (a square shell); the most efficient shape for bending in any direction, however, is a cylindrical shell or tube.

Which type of sections are most efficient for beams subjected to bending?

The most efficient shape for both directions in 2D is a box (a square shell); the most efficient shape for bending in any direction, however, is a cylindrical shell or tube. For unidirectional bending, the I or wide flange beam is superior.

What are the best shafts for torsion?

In general the two best sections for torsion are circular and hollow circular (tube). That’s why shafts use these shapes. Pretty much all the remaining sections are much worse because they have sharp edges. Comparing their polar moments of inertia will give you a hint too. But what about the difference between solid and hollow circular shafts?

What is the best material for torsion resistance?

Hope this might help you. Circular sections are the best for resisting torsion because they are more uniform in nature. Sqaure, Rectangular and other polygonal sections have sharp edges or fillets which reduce surface area thus increasing the stress in those places.

Why are circular sections the best for resisting torsion?

Circular sections are the best for resisting torsion because they are more uniform in nature. Sqaure, Rectangular and other polygonal sections have sharp edges or fillets which reduce surface area thus increasing the stress in those places.

What is the best shape for pipe torsion resistance?

Circular closed shapes, such as round HSS and steel pipe, are most efficient for resisting torsional loading. Other closed shapes, such as square and rectangular HSS, also provide considerably better resistance to torsion than open shapes, such as W-shapes and channels.
