Distance covered is the area under the line. Each time interval is coloured differently. The distance covered in the second and subsequent intervals is the area of its trapezium, which can be subdivided into triangles as shown. As each triangle has the same base and height, they have the same area as the triangle in the first interval.
It is typically a writing surface with a pre-printed compass rose of polar coordinates about a central point, often including adjacent linear scales, and sometimes a time/speed/distance nomogram. [1] With the aid of a marking device, dividers , and parallel rulers , the maneuvering board provides a template for graphical solution of relative ...
A Magic Triangle image mnemonic - when the terms of Ohm's law are arranged in this configuration, covering the unknown gives the formula in terms of the remaining parameters. It can be adapted to similar equations e.g. F = ma, v = fλ, E = mcΔT, V = π r 2 h and τ = rF sinθ.
One of the sensors is typically a digital camera device, and the other one can also be a camera or a light projector. The projection centers of the sensors and the considered point on the object's surface define a (spatial) triangle. Within this triangle, the distance between the sensors is the base b and must be known. By determining the ...
Step 5. Measure length of course by using speed of 8.8 knots and converting into nautical miles via the time, speed, and distance scale; Step 6. Connect the two ends of the vectors from the current course to the course made good. Thus creating your set and drift vector; Step 7. Using the navigational triangle, place on set and drift vector.
A time–distance diagram is a chart with two axes: one for time, the other for location. The units on either axis depend on the type of project: time can be expressed in minutes (for overnight construction of railroad modification projects such as the installation of switches) or years (for large construction projects); the location can be (kilo)meters, or other distinct units (such as ...
The wind triangle is a vector diagram, with three vectors. The air vector represents the motion of the aircraft through the airmass. It is described by true airspeed and true heading. The wind vector represents the motion of the airmass over the ground. It is described by wind speed and the inverse of wind direction.
An example of a velocity triangle drawn for the inlet of a turbomachine. The "1" subscript denotes the high pressure side (inlet in case of turbines and outlet in case of pumps/compressors). A general velocity triangle consists of the following vectors: [1] [2] V = absolute velocity of the fluid. U = blade linear velocity.
