What does a dashed line mean in science?
A wedge and dash projection is a drawing, a means of representing a molecule in which three types of lines are used in order to represent the three-dimensional structure: Dashed lines to represent bonds that extend away from the viewer. Wedge-shaped lines to represent bonds oriented facing the viewer.
Are symbols in a schematic shown in their energized or de energized condition?
Reading Electrical Diagrams and Schematics For electrical schematics that detail individual relays and contacts, the components are always shown in the de-energized condition (also called the shelf-state).
What do you call a dashed line?
The red line is called a “dotted line” (. . . . .) and unshown is a “dashed line” (- – – – -) because one uses dots and the other uses dashes. Blue line would have an unfamiliar name to a layman, technically called a dash-dotted line (. – . – . -)
What is the difference between a schematic and a wiring diagram?
A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. This is unlike a schematic diagram, where the arrangement of the components’ interconnections on the diagram usually does not correspond to the components’ physical locations in the finished device.
What do the dashed lines mean in a schematic diagram?
Schematic diagrams often contain dashed lines. In the schematic diagram shown in Figure 9–12, dashed lines indicate several different conditions. 1. Mechanical connection between two components such as those shown in electrical symbols 5, 8, and 9. Each of these symbols show a dashed line connected between different components.
When to use a dotted line or a dashed line?
In the image above a dotted line is used to represent what is hidden beneath the body. However the dashed or dotted line can also be used to represent movement. The dashed line that represents ‘cut here’ is implying an action as well as a boundary.
What does the dashed line mean on a control circuit?
The dashed line indicates that when one component is changed the other one is changed, at the same time. The double-acting push buttons illustrated in number 5 will both operate when one of them is pushed. 2. Field wired or installed components. 3. Components used only in special circumstances. 4. Factory wired or installed components.
What do dashed lines mean in a photograph?
In the case of the time lapse photograph, Maray’s initial drawing on the body appears to fuse drawing and photography into a new medium. However dashed lines can also be used to represent movement in time in a slightly different way. Something can be in one place then another.
