Current training instructs engineers or other constructors of such obstacles to fell trees, leaving a 1 or 2 yard stump, in such a manner as the trees fall interlocked pointing at a 45-degree angle towards the direction of approach of the enemy.

On his own initiative, Foley decided to exploit this tactical error and changed his angle of approach to sail through the gap.

Since this angle varies depending on system loading and generation, it is undesirable for the angle to approach 90 degrees.

The radio waves they generate strike the ionosphere at the right angle to pass through it only at high latitudes, where the lower ends of the gap approach the upper atmosphere.

The high speed rail line HS1 from Kent to north London passes the crossing approach roads on the north side of the river, at a near right angle.

The falls are viewable from a steep angle on the American side, where it is possible to approach to within several meters of the edge of the falls.

Straightforward, possibly a glacial approach, snow and ice will often be at an easy angle.

It can be converted into the true anomaly, which does represent the real geometric angle in the plane of the ellipse, between periapsis ( closest approach to the central body ) and the position of the orbiting object at any given time.

It would also allow them to approach record companies again from a different angle.

The position and angle of the lake in conjunction to the castle in reality obviously proves that the precise bombing-run would have needed a downhill approach to the west of the castle to line-up the aircraft in heading, altitude, speed and distance in time before being able to release the weapon precisely on target.

By setting the bombsight to that angle, the " range angle ", the aircraft simply had to approach the target and drop its bombs when the target appeared lined up with the sights.

In linear approach angle of rod torsion α does not depend on its cross-section form and is defined only by current density and magnetoelastic properties of the rod:

Because they were designed to be seen on a curved screen, the geometry looks distorted on television ; someone walking from left to right appears to approach the camera at an angle, move away at an angle, and then repeat the process on the other side of the screen.

Angle parking, known as echelon parking in Britain, of cars is similar to perpendicular parking for these vehicles, except that cars are arranged at an angle to the aisle ( an acute angle with the direction of approach ).

" Even if a guitar is built so that there are no " fret or neck angle errors, inharmonicity can make the simple approach of tuning open strings to notes stopped on the fifth or fourth frets " unreliable.

With the advent of auto-reverse ( playing the tape in both directions ), Nakamichi had long recognized that the angle of the tape passing over the playback head was not the same if the tape head was rotated in the opposite direction and its first approach was to track the azimuth on the tape itself by moving the head slightly-a very complex affair which led to the design of the Dragon with its NAAC, subsequently Nakamichi never revisited this approach and set its engineers in search of a more elegant solution.

These signal aspects corresponded with upper-quadrant semaphore signal positions: vertical display for proceed, a 45 ° angle display for approach, and horizontal display for stop.

Additionally, a row of lights at a 45 ° angle leaning left of vertical ( perpendicular to the approach aspect ) was also used for a restricting aspect.

Another approach to computing the dihedral angle is first to pick an arbitrary vector V that is not tangent to either of the two planes.

In 1967, applying a satirical angle to a fashion for the inclusion of " superman " inspired characters in UK television commercials, Milligan dressed up in a " Bat-Goons " outfit to head up a series of television commercials for British Petroleum.

None of the options for closing the angle between the lines presented a favourable option to the British commander: any maneouvre to bring ships closer would limit its firing ability to its bow guns, and potentially expose its decks to raking or enfilading fire from the enemy ships.

A right triangle ( American English ) or right-angled triangle ( British English ) is a triangle in which one angle is a right angle ( that is, a 90-degree angle ).

As the battle opened, the French and Spanish were in a ragged line headed north as the two British columns approached from the west at almost a right angle.

From the 1930s, following the work of Val Page, most British four-stroke parallel-twin motorcycles used a crank angle of 360 °, which allowed the use of a single carburettor because 180 ° and 270 ° twins need twin carburettors, as did an early Meguro was a copy of the 360 ° British BSA A7.

The use of the term " angle of incidence " to refer to the angle of attack occurs chiefly in British usage.

Some British authors have used the term angle of incidence instead of angle of attack.

The British ace Albert Ball, in particular, was a great exponent of this technique and had developed the tactic of getting under and just behind his adversary, and with his upper-wing mounted machine gun in his SE. 5, pulled down on its ratchet tracks at an angle of 45 °, was able to shoot down the enemy from below.

In 1859, British surgeon William Bowman used an ophthalmoscope ( recently invented by Hermann von Helmholtz ) to diagnose keratoconus, and described how to angle the instrument's mirror so as to best see the conical shape of the cornea.

The band has been compared to many classic British rock bands, as their angle on rock is uniquely English.

The British II Corps, on the left of the British line, occupied defensive positions along the Mons-Condé Canal, while I Corps was positioned almost at a right angle away from the canal along the Mons-Beaumont road ( see map ).

Captain Lanoe Hawker of the Royal Flying Corps, however, had mounted his Lewis gun just forward of the cockpit to fire forwards and outwards, on the left side of his aircraft's fuselage at about a 30 ° angle, on his Scout C, with serial number 1611, and with this aircraft on 25 July 1915, managed to defeat three German two seat observation aircraft to earn the first Victoria Cross awarded to a British aviator.

One British man became so annoyed at having his car clamped that he removed the clamp with an angle grinder.

The series takes great care with historical accuracy, covering the early days of the parachute, the fitting of weaponry to British biplanes ( lacking the Germans ’ interruptor gear, they had to be fired at an angle rather than through the propellers ) and the horrors of trench warfare.

Opposite the angle ring stood the British rolling mills, which opened in the 19th century and remained in use until 2005, by which time it was part of Brymill.

A miter joint ( mitre in British English ), sometimes shortened to miter, is a joint made by bevelling each of two parts to be joined, usually at a 45 ° angle, to form a corner, usually a 90 ° angle.

British Biograph's Panorama of Ealing from a Moving Tram ( 1901 ) is remarkable for its slow pace, high angle and the widescreen aspect of the 68mm film, whereas Danish film maker Thomas S. Hermanson's Sporvognene i Århus ( 1904 ) is remarkable for its speed and odd angles.

Lowering a concentrated, heavy weight down the anchor line – rope or chain – directly in front of the bow to the seabed, behaves like a heavy chain rode and lowers the angle of pull on the anchor.

Similarly, the angle that a line makes with the horizontal can be defined by the formula

For the simple case where the direction of the light beam along the line SE is perpendicular to the motion of the observer then only light emitted at an angle equal to the arc cosine of the ratio of the observer's speed to the speed of light will reach the telescope.

In addition, a rotation axis at an angle to the magnetic axis may be spinning different bands of magnetically-sorted elements into the line of sight between Alioth and the Earth.

Fishing line lends itself better to right angle weave because it is stiffer than nylon thread, so holds the beads in a tighter arrangement and does not easily break when tugged upon.

Right angle weave is done using both ends of the fishing line, in which beads are strung in repeated circular arrangements, and the fishing line is pulled tight after each bead circle is made.

In more generality, reflection across a line through the origin making an angle with the x-axis, is equivalent to replacing every point with coordinates ( x, y ) by the point with coordinates ( x < nowiki >'</ nowiki >, y < nowiki >'</ nowiki >), where

* Disclinations are line defects corresponding to " adding " or " subtracting " an angle around a line.

The eccentric anomaly t is the angle of the blue line with the X-axis.

Thales ' theorem, named after Thales of Miletus states that if A, B, and C are points on a circle where the line AC is a diameter of the circle, then the angle ABC is a right angle.

Euler discussed a generalization of Euclidean geometry called affine geometry, which retains the fifth postulate unmodified while weakening postulates three and four in a way that eliminates the notions of angle ( whence right triangles become meaningless ) and of equality of length of line segments in general ( whence circles become meaningless ) while retaining the notions of parallelism as an equivalence relation between lines, and equality of length of parallel line segments ( so line segments continue to have a midpoint ).

Here, x is the angle that a line connecting the origin with a point on the unit circle makes with the positive real axis, measured counter clockwise and in radians.

Which conic section is formed depends on the angle the plane makes with the axis of the cone, compared with the angle a line on the surface of the cone makes with the axis of the cone.

If the angle between the plane and the axis is less than the angle between the line on the cone and the axis, or if the plane is parallel to the axis, then the conic is a hyperbola.

Experiments showed that the surface chemistry and geometry at the contact line affected the contact angle and contact angle hysteresis, but the surface area inside the contact line had no effect.
