A chisel, thin in proportion to its width. It has a tang to enter the handle instead of a socket for receiving it. Knight.

culptor's chisel for smoothing. -- Flat file, a file wider than its thickness, and of rectangular section. See File. -- Flat nail, a small, sharp-pointed, wrought nail, with a flat, thin head, larger than a tack. Knight. -- Flat paper, paper which has not been folded. -- Flat rail, a railroad rail consisting of a s…

A drawplate with a narrow, rectangular orifice, for drawing flat strips, as watch springs, etc.

flies. -- Fly paper, poisoned or sticky paper for killing flies that feed upon or are entangled by it. -- Fly powder, an arsenical powder used to poison flies. -- Fly press, a screw press for punching, embossing, etc., operated by hand and having a heavy fly. -- Fly rail, a bracket which turns out to support the h…

Having freedom of motion interfered with by collision or entanglement; entangled; -- opposed to clear; as, a rope or cable may get foul while paying it out.

igonometrical functions, or Circular function, the lengths of arcs relative to the sines, tangents, etc. Thus, AB is the arc whose sine is BD, and (if the length of BD is x) is written sin - 1x, and so of the other lines. See Trigonometrical function (below). Other transcendental functions are the exponential functions…

ntial galvanometer. See under Differental, a. -- Sine galvanometer, Cosine galvanometer, Tangent galvanometer (Elec.), a galvanometer in which the sine, cosine, or tangent respectively, of the angle through which the needle is deflected, is proportional to the strength of the current passed through the instrument.…

which the point of sight is taken at the center of the sphere, and the principal plane is tangent to the surface of the sphere. "The gnomonic projection derives its name from the connection between the methods of describing it and those for the construction of a gnomon or dial." Cyc. of Arts & Sciences.…

er. "Hampered nerves." Blackmore. A lion hampered in a net. L'Estrange. They hamper and entangle our souls. Tillotson.

The part of any tool next the tang or handle; as, the heel of a scythe.

A nonplane curve whose tangents are all equally inclined to a given plane. The common helix is the curve formed by the thread of the ordinary screw. It is distinguished from the spiral, all the convolutions of which are in the plane.

To become entangled or caught; to be linked or yoked; to unite; to cling. Atoms . . . which at length hitched together. South.

lants in fields and gardens. It is made of a flat blade of iron or steel having an eye or tang by which it is attached to a wooden handle at an acute angle.

point of the one corresponds one and but one point in the other, and vise versa. Thus, a tangent line rolling on a circle cuts two fixed tangents of the circle in two sets of points that are homographic.

Fig.: To entangle; to hamper. Dr. H. More.

gh the eye of the spectator and at right angles to the vertical at a given place; a plane tangent to the earth's surface at that place; called distinctively the sensible horizon.

A built-up, rifled, rapid-fire gun of oil-tempered steel, having a rectangular breechblock which moves horizontally or vertically in a mortise cut completely through the jacket. It is made in France.

ctions which have relations to the hyperbola corresponding to those which sines, cosines, tangents, etc., have to the circle; and hence, called hyperbolic sines, hyperbolic cosines, etc. -- Hyperbolic logarithm. See Logarithm. -- Hyperbolic spiral (Math.), a spiral curve, the law of which is, that the distance from t…

To insnare; to entrap; to entangle; to catch. Let not the surpassing eloquence of Taylor dazzle you, nor his scholastic retairy versatility of logic illaqueate your good sense. Coleridge.

To entangle as in a cobweb; to mix confusedly. [R.] Hudibras. Physiology imbrangled with an inapplicable logic. Coleridge.
