102 Flashcards
A schematic is made up of
symbols and lines
Double - line drawings that show the internal details of a pneumatic system are called
cutaway drawings
In a DC circuit the electrons flow from
one direction only
Arrows are used on piping diagrams to indicate the
direction of flow
in a piping system an alternate flow pattern is indicated by a
supplementary diagram
on an electrical diagram a dashed line indicates a(n)
exposed wire
vent lines and drain lines are shown on a hydraulic schematic by
dashed lines
if a schematic carries no legend, clues about it may be found in the parts list, drawing title, and
Engineer notes

Parallel
A wiring diagram shows how the parts of a circuit are connected
externally
Wires labeled 1 on a schematic
Carry power from the source
In the displayed diagram the “FORWARD” button is marked
FOR
The flow of material in a piping system is controlled and adjusted by
Valves
Which displayed symbol represents a flanged joint
D
Direction of flow in a piping system may be changed by a(n)
