Simplifying Torsional Load Design | Utilizing Square Hollow Sections in Structural Engineering.

In this video, we will be discussing how to determine the size of a suitable square hollow section for a 3 meter long beam that supports a design load of 60 kilonewtons. We will go over the importance of using a hollow, closed cross sectional geometry for resisting torsional loads & a mathematical formula for determining stress levels. We will also calculate the reaction force, maximum bending moment, & applied torque.

This is my favourite channel. I especially like it when you explain everything so nicely. I wish you a lot of success 🙌

[@gowthamiv4841]

This is highly extra ordinary.. 😍
Understanding all together in a simple manner..

[@LvPatriot1]

Simply amazing, thanks a lot.

[@ahmadalam5624]

Can this method work for any section of only shs

[@GeniusD18]

Wouldn't it be more appropriate to consider shear force is 60 kN, designing for the worst case where section is cut right at the 60 kN point load? It would not change the outcome since our allowable shear stress is so high.

Can you post video of global axis and local axis of members plays a role in Design??

[@gowthamiv4841]

Can you post the video regard this?

How plastic section modulus arrived as 90.90 cm3 it's not tallying in cm's..and bending stress why we need to consider as 50kn?

[@StructuralEngineerCalcs]

Thank you for your question regarding the plastic section modulus & bending stress calculations in the video. The plastic section modulus is calculated by dividing the maximum bending moment by the strength of mild steel, which results in 90.9 cm^3. The bending stress of 50 kN is used to determine the beam's dimensions & check the combined stress from bending & torsion. In conclusion, the video suggests using a 100x100x8 square hollow section as the optimal choice for the beam.
