I always use SI so I don’t get confused and then the result will be in Nm. Or you can just integrate it out yourself. Although superposition methods are close enough, they are approximate, as the point of maximum deflection is not the same for the different load types.
The bending stress is greatest in the middle; and when the ends are clamped, the stress is less than if they are free to bend. Register now while it’s still free! Calculated deflections, especially with wood, should always be suspect, due to variations in assumed loading, material quality, etc.
There are other issues too.
Structures, Beams: Proof of formulas for a beam
The Eng-Tips staff will check this out and take appropriate action. For Part 2, beam clamped at both ends, use their figure If this is for a spreadsheet, the deflection could be calculated at points along the beam’s span, with the maximum of those deflections used.
Thank you for a swift response. However, for any given point, superposition would give you the exact deflection at that point.
We all know the answer but I do not know and can, for now, not think of a simple logical way of deriving it using basic principles of mechanics. A star for rb for being “older, crankier, hand-calc’ing engineer. Register a new account. If I have a simple beam with two supports and a static load, does placing the load in the center push the beam closest to breaking catastrophic failure?
Download Now Defense manufacturing is all about project manufacturing and project accounting. Glad you’re feeling formullas about it! By Structengineer11October 17, in Structural. Obviously the local strength of the beam matters a great deal: Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

Just seems like you are expecting a bit too much accuracy given the material being used. I hadn’t looked at figure 3 and assumed it only gave maximum deflections. Students Click Here Join Us!
