Truncated Cone Flashcards
Conical layout can be described as
Developing a pattern for a right cone using an Apex
When developing patterns for 90 conical “T” how many views are needed
One
When developing a pattern for conical “T” that’s not on a 90 requires
Two views
Why is there a baseline constructed under the centre on end view
To simplify and unclutter the end view
After transferring development of mitre points on the side of the conical view we attain
True lengths
Formula for Apex
VH x LD/ LD-SD
Two views are needed for conical “T” on a 60 , what views are needed
Elevation view
End view
Layout of the whole cones needs to done you can develop
Stub view
Where are conical “T found
Commercial settings
Pipe “T on cones use what kind of pattern development
Radial line
Conical “T on round pipe uses what kind of pattern development
Radial line
Pipe “T on a cones use are used for what set up
Dust collection
Reference line is also known as a
Auxiliary line
Development of irregular curves require at least how many points
Three
All arcs and curves are called
Sectional curves
Sectional curves created are
Reducing radial curves
Sectional curves can be found in what fitting
45 fitting
What view is developed from sectional curves
Hole mitre view
What must be developed on elevation view prior to creating hole pattern
Mitre
The hole pattern for 45 using what kind of layout
Radial line
Pipe “T on a cones use are sometimes referred to
Stub Y’s
Vertical pipe “T on cones use uses what development
Stretch out for “T uses parallel
The cone uses development from the Apex
Conical layout can be described as developing a pattern for
Right angle using Apex
Come on a pitch are usually found
In residential home for roof jacks
Roof jack on pitch on requires how many patterns
1/2 pattern
Element lines are always drawn from
Apex to base
A commercial tee usually accompanies what other fitting
Reducer
Oblique cones use what kind of development
Radial line
Oblique cylinders and boots use what development
Parallel line and line to line
Where are boot tees found
In dust collection
Right cylinder cross section is at a right angle to ?
The centre line
On centre boot t uses what views
Elevation and right view
Boot t on centre only requires how many views
Half view
Right cone on a right angle at shown how
Apex directly above the centre of it base
Oblique cones apex will be located where to the base line
Not centred
Vertical apex will not work for what fitting
Oblique fitting
What is secondary line
Line from vertical apex (A) straight down to make (B) apex
When drawing oblique cones element lines are to help get
True length lines
