What is the planometer?
Planometer is a tool used to measure a two -dimensional surface, usually one that is too complex for manual measurement. The device mechanizes the process of calculating the area using the formula known as Green's sentence. While the planometer can be used on the small physical regions themselves, it is commonly used to represent a scale such as a map. As a somewhat simplified explanation, the use of a sentence dividing the area into so many rectangles as fit. The remaining areas will consist of a straight edge of the rectangle and a curved edge along the outside of the area. However, the elaboration of the curved sections is more complicated. The Green sentence uses available information to calculate the area of these sections. Although it is quite sippodle standards of the number would be Green's sentence so complicated and time consuming to use to largely impractical for the calculation of man in the area.
Planometer automates this process. In its most common form, the polar planometer, it resembles human arm from the shoulder on the wrist. "ArmWell ”is usually a metal cylinder that is fastened in the position, but can rotate. The" wrist "is a moving indicator used to track throughout the area. The "elbow" is a hinge that can move in both directions.
This setting means that the hinge is affected by the direction and distance the indicator travels. The planometer will have a bike near the "elbow" that this data measures. This wheel either slips or turns, depending on the direction in which the indicator travels.
When the wheel rotates, the connected display measures its rotation. The number of rotations is proportional. It is set so that once the indicator travels around the perimeter of the area, the figure on the scale shows the size of the area. This mechanical operation removes the need to calculate the area with a green sentence.
theoretically, the planometer can be used to measure two -dimensional areas in life -size. In practice, there is only a small demand with the areas that are sufficiently small, andit would be practical. In fact, the planner is usually used on the scale of the area. This can often include soil area measurements using planomer on the map. The petitioner can also be used for plans for the building.
