| Starting tap
|
|
A threaded tool with a tapered end, which makes it easier to start cutting the internal threads in a hole easier. When the tapered end is inserted into the hole, shallow starting cuts are created by the first threads on the tap. |
| Starting torque
|
|
The torque at the bottom of a speed (rpm) versus torque curve. The torque developed by the motor is a percentage of the full-load or rated torque. At this torque the speed, the rotational speed of the motor as a percentage of synchronous speed is zero. This torque is what is available to initially get the load moving and begin its acceleration. |
| State housing act
|
|
Law of the state that establishes guidelines and requirements for construction of buildings. The standard may differ from state to state. |
| Statement of consideration
|
|
Enumeration of the consideration given by each party to a contract, which in some cases must be in written form to be enforceable. The statute of fraud requires that all contracts for the sale of real estate be in writing. |
| Static
|
|
(1) Electrical discharges in the atmosphere that interfere with radio or television reception. (2) Not moving or progressing. At rest. Inactive. Stationary. |
| Static coefficient of friction (cof)
|
|
The degree of slip resistance presented in a quantitative number that expresses the degree of slip resistance. Slip resistance is evaluated by the horizontal pull method (ASTM C1028). There is no current ANSI requirement a coefficient of friction of 0.5 and above is the recognized industry standard for a slip resistant floor. |
| Static discharge head
|
|
The vertical distance from the pump to the highest outlet in the water system Stand By Loss. The amount of heat lost while a unit is in stand by mode. |
| Static load
|
|
Acting through weight only. Downward pressure exerted by a motionless body or mass. |
| Static pressure
|
|
The pressure when no water is flowing. |
| Static pressure curve
|
|
Manufacturer's graph which helps engineers match the fans and HVAC systems, by showing the relationship between the static output pressure of a fan and its output volume at a specific speed. |
