Case(s) in Point
In the example (here) I discussed a person standing on a wood plank, and `examining’ the deflection. Talk is cheap. I grabbed three pieces of lumber (that I milled) in my shop: one piece a 1 x 5 Southern Pine …
Shear Deflection – Prefab Wood I-Joist
Shear Deflection – Prefab Wood I-Joist Example Calc (c) Jeff R. Filler, Pell City, 2022 Continuing our discussion on shear deflection of wood beams (joists, etc.), let’s look at a prefabricated wood I-joists. Basic design information for prefabricated wood I-joists …
E min
E min (c) Jeff R. Filler, Pell City, Alabama, 2022 But First, E apparent and E true `E min’ is calculated wood property used in the design of structural wood members (beams, columns, etc.). It is a derived property, derived …
Accuracy of Deflection Calcs (and Eee)
In the example above (link) we calculated a deflection of 0.599 in. How accurate is this number? (I showed it to three significant figures … accurate to half a percent?) Leaving out, for now, the accuracy/precision of the other input, …
E app (Apparent Modulus of Elasticity)
E app (`Eee app’, `Eee apparent’, Apparent Modulus of Elasticity) is a design property for wood construction. It comes from the Modulus of Elasticity of the wood (E, MOE, Young’s Modulus). It’s not a `true’, or `pure’ property, and it …
`Eeee’
E (Eeee!) (Steel for now; wood later) E stands for Modulus of Elasticity, or Elastic Modulus, also Young’s Modulus. It is also abbreviated MOE (`Em – Oh – Ee’). By definition it is the amount of stress (tensile or compression) …
