" Warp "
| Any variation from a true or plane surface. Warp includes bow, crook, cup, and twist, et. |
" Tension Wood "
| Abnormal wood found in leaning trees of some hardwood species and characterized by the presence of gelatinous fibers and excessive longitudinal shrinkage. Tension wood fibers hold together tenaciously, so that sawed surfaces usually have projecting fibers, and planed surfaces often are torn or have raised grain. Tension wood may cause warping. |
" Tangential "
| Strictly, coincident with a tangent at the circumference of a tree or log, or parallel to such a tangent. In practice, however, it often means roughly coincident with a growth ring. A tangential section is a longitudinal section through a tree or limb perpendicular to a radius. Flat-grained lumber is sawed tangentially. |
" Tack "
| The property of an adhesive that enables it to form a bond of measurable strength immediately after adhesive and adherend are brought into contact under low pressure. |
" Symmetrical Construction "
| Plywood panels in which the plies on one side of a center ply or core are essentially equal in thickness, grain direction, properties, and arrangement to those on the other side of the core. |
" Substrate "
| A material upon the surface of which an adhesive-containing substance is spread for any purpose, such as bonding or coating. |
" Structural Sandwich Construction "
| A layered construction comprising a combination of relatively high-strength facing materials intimately bonded to and acting integrally with a low-density core material. |
" Stressed-Skin Construction "
| A construction in which panels are separated from one another by a central partition of spaced strips with the whole assembly bonded so that it acts as a unit when loaded. |
" Stress-Wave Timing "
| A method of measuring the apparent stiffness of a material by measuring the speed of an induced compression stress as it propagates through the material. |
" Strength Ratio "
| The hypothetical ratio of the strength of a structural member to that which it would have if it contained no strength-reducing characteristics (knots, slope-of-grain, shake, etc). |
