Top 10 Structural Engineering Formulas You Need to Know.

I have learned so much from the tools of equations and formulas uses. Thank you

The torsional stiffness of a beam equation is a bit simplified. bh^3/3 would be correct if b is the larger dimension and h is the smaller dimension, and if b is much larger than h. In other words the torsional stiffness would be considered as the width times the thickness^3 and the denominator is approximately 3 when b/h is greater than 10. It is hard to limit the equations to just 10 because you miss important equations such as wl^2/8 and pl/4. I think deflection of a cantilever beam is important because you can derive so many other equations from it- pl^3/(3EI). That gets you to at least 13 equations.

For which cross-section of the beams this torsional stiffness formulae can be used? And how to calculate torsional stress?

[@StructuralEngineerCalcs]

Thank you for your comments and questions! The torsional stiffness formula can be used for any cross-section of a beam as long as it is symmetrical about its centroidal axis. To calculate torsional stress, you can use the formula T = (Twist angle x polar moment of inertia)/(beam length x polar section modulus). It's important to note that this formula is only applicable for beams subjected to pure torsional loading. If the beam is also subjected to other types of loading, such as bending or shear, you will need to consider these as well in your calculations.

Thanks for the useful videos!Will you able to make some videos for temporary works. Like design of platform for cranes or checking the stress on lifting points and etc. Thanks.

[@StructuralEngineerCalcs]

Thank you for your suggestion! We will consider making videos on temporary works in the future. In the meantime, please check out our existing videos on the design of structural elements such as beams, columns, and foundations, as these principles can also be applied to temporary works design. Additionally, it is always important to consult with a qualified, experienced, and chartered engineer to ensure the safety and efficacy of your temporary works design. Thanks for watching!

deflection of simple single-span hinged beam is 5*w*l^4/384*E*I but not 5*w*l^3/384*E*I

[@marcofernandes7622]

Is the deflection equation l^4?

[@billj5645]

In the context of this video it should be a 4. In some other contexts it could be a 3 because W is sometimes defined as w times l so one of the l is already included there. It's a matter of little w vs. capital W notation.

Morning! Merry xmas guys. Can I propose a supplement to add to this in a follow up video. Could you provide the units expressed in each of the equations pls??

[@StructuralEngineerCalcs]

Thank you for your suggestion! Adding the units to the equations would definitely be a useful addition to the video. I'll make sure to include them in a follow-up video. In the meantime, if you have any specific questions about the units in the equations, feel free to ask and I'll do my best to help clarify.
