Standard knot to Starting crank

rate testing, a cell in which the voltage remains constant is desir­able. In use, no appreciable amount of current is drawn from the cell. The Clark cell was the first stan­dardized cell. The Weston is in general use today.
Standard knot. (Wood) A sound knot not over 11,12 in. in diameter.
Standard pressure. (Plumb.) Term applied to valves and fittings suit­able for a working steam pressure of 125 pounds per square inch.
Standing matter. (Print.) Type com­position kept standing to be used for further printings. .
Standpipe. (Engin.) A large vertical pipe or water tower which serves as a reservoir, and is used to se­cure a uniform pressure in a sup­ply system. .
Stanniferous. (Ceram.) An opaque white glaze. Staple. A V-shaped piece of wire or iron. with sharpened points for driving into wood.
Star connection. (Elec.) Three-phase generators and transformers have three coils which may be con­nected, star, Y, or delta. When one terminal of each coil is connected together and the other three termi­nals are brought out separately, the connection is called star or Y. Star drill. A tool with a star-shaped point used for drilling in stone or masonry. .f~/
Star feed. (Mach.) An intermittent feed accomplished by a star wheel attached to the cross slide screw. A bolt or pin fastened to the lathe faceplate on each revolution strikes a point on the star wheel causing the cutting tool to advance. The same principle has various appli­cations.
Starling. (Arch.) An enclosure made by driving piles close together as for protection about a bridge or pIer.
Star shake. (Carp.) A radial split or crack in a log or timber as a result of being cut green and drying too rapidly. The crackes or splitS which may be seen radiating from the centrer in an end view of a timber.
Starter. (Auto.. Elec.) A series elec­tric motor used on automobiles to turn over the gasoline engine until it starts under its own power.
Starterator. (Auto.) A linkage which makes it possible to operate the starting motor by depressing the accelerator pedal.
Starting box. (Elec.) A rheostat con­tained in a case having a switch arm and contact points for deli­vering the current gradually by cutting out one resistance after an­other.
Starting circuit. (Auto.) On closing the starting switch, the current flows from the positive post through the heavy lead to the switch, to the starting-motor-field winding, to the brushes, to the ar­mature winding then off the com­mutator through the two remain­ing brushes to the ground of the starting motor. It then returns to the battery through the car frame, and up through short grounding cable to the negative post of the battery.
Starting crank. (Auto.) A crank for­Starting motor to Stationery engine merly used for turning over the engine in order to start it. Since the invention of self starters, the starting crank is rarely used ex­cept during certain types of repair jobs.
Starting motor. (Auto.) The electric motor by means of which the en­gine is cranked by closing the elec­tric circuit.
Starting newel. (An:h. and Bldg.)The post at the bottom of a stair,supporting the balustrade.
Starting step. (Bldg.) The lowest step at the bottom of a stair.
Starting torque. (Elec.) The turning effort produced by a motor upon its shaft through the electromag­netic effect at the initial flow of current.
Startix. (Auto.) A solenoid which automatically closes the starting~, motor swftch as soon as the ignitbn switch is turned on.
Static balance. That state of balance which exists when the weight of' a pulley or shaft is so distributed that when lightly supported there I. is no heavy side to roll to the bottom.
Static balanced surface. (Aero.) A , control surface whose center of ' mass is in the hinge axis.
Static ceiling. (Aero.) The altitude in standard atmosphere at which an aerostat is in static equilibrium after removal of all dischargeable weights.
Static electricity. Differs from cur­rent electricity in that it is electric­ity at rest. One method of genera­tion is by frictional contact, as the charge placed upon a glass rod by rubbing with silk or fur.
Static friction. (Engin.) That friction between two bodies when there is a tendency to, but not an actual slipping of, one with regard to the other.
Static loaeL (Engin.) A load at resL Statics. (Engin.) That branch of me­chanics which treats of the equi­librium, pressure, weight, etc., of bodies at rest.
Static stability. (Aero.) Stability of such a character that, if the air­plane.is displaced slightly fn?m its normal altitude by rotation about an 'axis through its center of gravity, moments come into play which tend to return the airplane toward its original alti-tude.
Static thrust. (Aero.) The thrust "de~eloped by a propeller whenn rotatin without translation.
Static turn mdicator. (Aero.) Alum indicator actuated by the differ­ence in pressure between static tubes mounted near the wing tips equidistant from the plane of symmetery and in a plane parallel to the lateral axis.
Stationary engine. (Eng in.) An engine located on a fixed found­
