The Big E and the Five Little f ’s Download as PDF
| Engineering Term | Meaning | |
|---|---|---|
| E (Modulus of Elasticity) |  | How much this sample will deflect under a given load. |
| Fb (Extreme fiber stress before failure occurs) | | How much we can stress a member in bending before permanently rupturing fibers. |
| fcii (Compressive strength when loaded parallel to grain) |  | How much load we can put on the member when loaded like this before rupturing fibers. |
| fv (Horizontal shear) |  | How much load we can apply as shown before material will fail along the indicated failure plane. |
| ft (Tensile strength parallel to grain) |  | How much tension we can put this member under before failure. |
| Fc⊥ (Compressive strength loaded perpendicular to grain) |  | How much load we can apply in this manner before actual crushing. |
