Section E – Layout
1) On a 50-division inch vernier height gage, the vernier index is coincident at the 23rd line. This
1) A surface plate provides an accurate reference plane from which measurements can be made
2) Surface plates may be made of cast iron, granite, or marble
3) Cast iron surface plates are superior to granite surface plates.
4) Surface plates are available in various grades.
2) Each one-tenth inch division of the beam scale of the 25 division inch vernier height gage is
subdivided into ________ parts.
A) 2
B) 3
C) 4
D) 5
3) Each vernier graduation on a 50 division metric vernier height gage is equal to ________ mm.
A) .50
B) .001
C) .02
D) .01
4) The first step in using any height gage after cleaning the surface plate, is to check the:
A) Column for perpendicularity
B) Vernier alignment at the top of the beam scale
C) Base for cosine error
D) Alignment of the vernier and beam scale zero indexes
5) When scribing perpendicular lines, the workpiece must be:
A) Inverted
B) Set on a parallel bar
C) Turned 90 degrees
D) Left as is and the height gage used on an angle plate
6) Layout lines scribed with a height gage should be:
A) Short, dashed lines
B) Only deep enough to remove the layout dye
C) Scribed so that a permanent mark is left on the workpiece
D) Scribed repeated times to insure a visible mark
7) Height gages are used for precision layout.
8) Which tool can be used for precision angle layout?
A) Angle vise
B) Protractor
C) Sine bar
D) Dividers
7) On a 25 division inch vernier height gage, the vernier is coincident at the 17th line. If the
beam scale reads 3.75, the total reading would be:
A) 3.733
B) 3.767
C) 3.7517
D) 3.766
8) On a 50 division inch vernier height gage, the beam scale reads 7.500 and the vernier is
coincident at the first mark past the zero index. The total reading would be:
A) 7.255
B) 7.501
C) 7.500
D) 7.499
9) On a metric height gage, the beam scale reads 151 and the vernier is coincident at the 37th
mark. The total reading would be:
A) 51.37
B) 151.74
C) 50.26
D) 150.37
