**tangent**planes are parallel. - 9) by the
**tangent**screw f, acting on a small toothed wheel clamped to the rod connected with the driving pinion, there was apt to be a torsion of the rod rather than an immediate action. - This wheel is acted on by a
**tangent**screw whose bearings are attached to the cradle; the screw is turned by means of a handle supported by bearings attached to the cradle, and coming within convenient reach of the observer's hand. - The formula for length of scale is, length = sighting radius X
**tangent**of the angle of elevation. **Tangent**sights were not much trusted at first.- - Theory of
**Tangent**Sight. - Fore-sights are made right and left;
**tangent**sights are interchangeable, the graduations are cut on the horizontal edges above and below, so that the sight can be changed from right to left or vice versa by removing and reversing the bar. - Draw the
at A and B, meeting at T; draw TV parallel to the axis of the parabola, meeting the arc in C and the chord in V; and M draw the**tangents****tangent**at C, meeting AT and BT in a and b. - The fact that C 1 does not give the true area is due to the fact that in passing from one extremity of the top of any strip to the other extremity the
**tangent**to the trapezette E, _- changes its direction. - If the
**tangent**at P meets the asymptotes in R, R', then CR.CR' = CS 2. - (io) The velocity q is zero in a corner where the hyperbola a cuts the ellipse a; and round the ellipse a the velocity q reaches a maximum when the
**tangent**has turned through a right angle, and then q _ (Ch 2a-C0s 2(3). - Accordingly for a given ellipsoid the surface density of free distribution of electricity on it is everywhere proportional to the the
**tangent**e plane e att that point. - The slowest speed is given by means of a
**tangent**screw which is carried by a ball-bearing on the flange of the telescope sleeve, whilst its nut is double-jointed to a ring that encircles the flange of the heliometer-tube. - It was not, however, till 1829 that a
**tangent**sight (designed by Major-General William Millar) was introduced into the navy; this was adopted by the army in 1846. - I it will be seen that in order to strike T the axis must be directed to G' at a height above T equal to TG, while the line of sight or line joining the notch of the
**tangent**sight and apex of the dispart or foresight must be (/ ?` directed on T. - Now the height to which the
**tangent**sight has been raised in order to direct the axis on G' is evidently proportional to the**tangent**of the angle OMS =AXS. - Other improvements were: the gun was sighted on each side,
**tangent**scales dropping into sockets in a sighting ring on the breech, thus enabling a long scale for all ranges to be used, and the foresights screwing into holes or dropping into sockets in the trunnions, thus obviating the fouling of the line of sight, and the damage to FIG. - - Laying by Full
**tangent**sight, the point of the fore g y sight and the target must be in line " Sight. - Except for some minor differences the
**tangent**sights were the same for all natures of guns, and for all services, but the development of the modern sight has followed different lines according to the nature and use of the gun, and must be treated under separate heads. - The normal method of laying these is from the fore-sight over the
**tangent**sight to a point in rear. - 19) represent a gun at height BD above water-level DC, elevated to such an angle that a shot would strike the water at C. Draw EB parallel to DC. It is clear that under these conditions, if a
**tangent**sight AF be raised to a height F representing the elevation due to the range BC, the object C will be on the line of sight. - In subsequent patterns all the deflection was given on the
**tangent**sight, which was provided with two scales, the upper one graduated in knots for speed of ship, and the lower one in degrees. - The
