|
| Set complete range |
| |
The maximum distance allowed between the actual position of a setworks and the position to which the setworks was sent. When the setworks position is in this range, the setworks is at set complete.

|
| Snatch block |
| |
A block that can be opened on one side to allow a cable or rope to be laid in the block, instead of threading it through from one end.

|
| Sorghum |
| |
A cereal grass used mainly for feedgrain or silage.
|
|
| Soybeans |
| |
A legume crop, native to the Orient, used mainly in the United States for high protein feed and oil.
|
|
| Specific gravity (SG) |
| |
Also called relative density. As applied to wood, the ratio of the oven-dry weight of a sample to the weight of a volume of water equal to the volume of the sample at a specified moisture content (green, air-dry, or oven-dry).
|
|
| Spool |
| |
A term loosely applied to almost any moving cylindrically shaped part of a hydraulic component which moves to direct flow through the component.
|
|
| Stack heat loss |
| |
Loss of combustion heat via gas emissions in the smokestack of chimney.
|
|
| Stalk |
| |
The straw or stem-like part of the plant that supports the seed head.
|
|
| Standard relief |
| |
Also known as Straight Relief. Outlet portion of a pellet die hole that has been counterbored straight.
|
|
| Starch |
| |
The main carbohydrate component of the dry matter in grain. Contains long chains of glucose molecules, which are easily broken down by rumen microbes.
|
|
| Steam |
| |
Vapor produced by heating water.
|
|
| Steam sprays |
| |
Mechanical equipment for introducing water vapor or steam to the kiln environment.
|
|
| Stem |
| |
The stalk of a plant.
|
|
| Stocker |
| |
Weaned cattle that are fed high-roughage diets (including grazing) before going into the feedlot.
|
|
| Straight feedstuff (Straights) |
| |
A vegetable or animal product in its natural state, fresh or preserved, intended as such for feeding to animals. Also an individual feed ingredient used in the production of compound animal feeds.
|
|
