However, axle 1 attaches to the gimbal at the red points on the red plane of rotation in the diagram, and axle 2 attaches at the blue points on the blue plane.

is confined to the " blue plane " in the diagram and is the result of the unit vector on the x axis being rotated through Euler angles

The diagram below shows a structure on a set of five elements: arcs connect the structure ( red ) to the elements ( blue ) from which it is built.

The blue forward on the left of the diagram is in an offside position as he is in front of both the second-to-last defender ( marked by the dotted line ) and the ball.

The blue striker | forward in the penalty box of the diagram is not in an offside position, as he is behind the ball, despite the fact that he is in front of all but one of his opponents.

This diagram illustrates the four decay chains discussed in the text: thorium ( in blue ), radium ( in red ), actinium ( in green ), and neptunium ( in purple ).

Four filaments of the gills of the blue mussel ( Mytilus edulis ) a ) part of four filaments showing ciliated interfilamentar junctions ( cj ) b ) diagram of a single filament showing the two lamella ( anatomy ) | lamellae connected at intervals by interlamellar junctions ( ilj ) and the position of the ciliated interfilamentar junctions ( cp )

With reference to the force diagram above, the vertical component of the normal force ( green arrow ) must equal the weight of the parcel ( red arrow ), which is, and the horizontal component of the normal force must equal the centripetal force ( blue arrow ) that keeps the parcel in circular motion, which is.

In the standard Hertzsprung – Russell diagram, blue giants are found in the upper left corner, due to their high luminosity and early spectral type.

Schematic of double-slit experiment in which Aharonov – Bohm effect can be observed: electrons pass through two slits, interfering at an observation screen, with the interference pattern shifted when a magnetic field B is turned on in the cylindrical solenoid, marked in blue on the diagram.

* In the diagram, the medians ( in blue ) intersect at the centroid G.

The Newberry Volcano lies at the northwest end of both the Brothers Fault Zone, and the High Lava Plains ( area of blue lines on diagram at right ) of volcanic features in central Oregon that have been developing since about 16 Ma.

Schematic diagram of ATCase structure, depicting spatial arrangement of green regulatory ( R ) and blue catalytic ( C ) subunits.

Each line of a diagram represents a particle propagating either backward or forward in time.

The ideal Diesel cycle follows the following four distinct processes ( The color references refer to the color of the line on the diagram.

Typical aerodynamic teardrop shape, assuming a viscous medium passing from left to right, the diagram shows the pressure distribution as the thickness of the black line and shows the velocity in the boundary layer as the violet triangles.

This is known as the mirror image rule and is related to the Franck – Condon principle which states that electronic transitions are vertical, that is energy changes without distance changing as can be represented with a vertical line in Jablonski diagram.

Each Feynman diagram is the sum of exponentially many old-fashioned terms, because each internal line can separately represent either a particle or an antiparticle.

Idealised Pressure volume diagram | Pressure / volume diagram of the Otto cycle showing combustion heat input Qp and waste exhaust output Qo, the power stroke is the top curved line, the bottom is the compression stroke

This color is approximately equivalent to the color of the CIE chromaticity diagram at the 430 nanometer line.

In this type of diagram, the molecular orbitals are represented by horizontal lines ; the higher a line the higher the energy of the orbital, and degenerate orbitals are placed on the same level with a space between them.

An unusual feature of the water phase diagram is that the solid – liquid phase line ( illustrated by the dotted green line ) has a negative slope.

Another interesting though not unusual feature of the phase diagram is the point where the solid – liquid phase line meets the liquid – gas phase line.

Feynman diagrams | Feynman diagram elementsThese actions are represented in a form of visual shorthand by the three basic elements of Feynman diagrams: a wavy line for the photon, a straight line for the electron and a junction of two straight lines and a wavy one for a vertex representing emission or absorption of a photon by an electron.

This can be seen in the concordia diagram, where the samples plot along an errorchron ( straight line ) which intersects the concordia curve at the age of the sample.

It is a p-T diagram indicating the solid and liquid regions separated by the melting curve ( between the liquid and solid state ) and the liquid and gas region, separated by the vapor-pressure line.

This is the line that separates two fluid regions in the phase diagram indicated by He-I and He-II.

* Straight-line diagram, a diagram of a road where the road is shown as a straight line

The line may be practical-a set by a road surveyor-or in a diagram that models a road or a roof either as a description or as a plan.

The circuit diagram of the Model 102 shows the direct connection of the receiver to the line, while the transmitter was induction coupled, with energy supplied by a local battery.

The dial switch in the base interrupted the line current by repeatedly but very briefly disconnecting the line 1 – 10 times for each digit, and the hook switch ( in the center of the circuit diagram ) disconnected the line and the transmitter battery while the handset was on the cradle.
