Cambium layer to Capacity load.

Cambium layer usually expressed as the ratio of de­parture of the curve from the chord to the length of the chord.

Camphor. (Chem.) A translucent, volatile, white resin made from an oriental evergreen, Extensive1y used in the manufacture of explosivs, celluloid, and disinfectants.
Camshaft. (Auto. Mech.) A shaft car­rying a series of cams which form integral parts of the shaft and are so spaced as to control the relative op­eration of the automobile engine valves.
Cam vise. (Mach.) A vise opened and closed by cam action.
Cannard airplane. (Aero.) A type of airplane having the horizontal stabi­lizing and ~ontrol surfaces in front of the main supporting surfaces.
Candelabra. A branched ornamental candlestick.

The upper or loose portion of a shaft bearing attached to the lower portion by screws or bolts. (Print.) The common name for a capital letter.
Capacitance. (Elec.) Generally, the ability to store up electricity. The capacitance of a condenser is meas­ured by the charge it will hold when the difference of potential across its terminals is one volt.
Capacitive reactance. (Elec..) The measure of resistance to the flow of an a.c. current through a condenser.
Capacitor. (Elec.) An electric con­denser.
Capacity. (Elec.) The quantity of elec­tricity which a condenser is able to store or condense is called its "elec­trostatic capacity."
