When choosing what size of lumber to use as a beam, we must consider various factors so we … See more

To find the deflection of a wood beam with the typical rectangular cross-section, we use this formula: delta δ – Deflection (in inches) at the midspan of the wood beam due to the l… See more

Now that we've checked the deflection of our beam, we can now check for its bending stress. For that, we first need to calculate the required or actual moment, M M, our bea… See more
