ENGINEERING DRAWING: In perspective projection, the horizontal plane in which the object is assumed to be situated is called ______________
a) horizontal plane
b) picture plane
c) ground plane
d) auxiliary ground plane
Answer: c
Explanation: In perspective projection, the horizontal plane in which the object is assumed to be
situated is called ground plane. And the imaginary plane is at the level of the eye above the ground
plane and at right angles to the picture plane is called the horizontal plane.
ENGINEERING DRAWING: If an isometric drawing is made use of isometric scale then the
drawings are called ___________
a) Isometric projection
b) Isometric view
c) Isometric perception
d) Orthographic view
Answer: a
Explanation: To avoid confusion, the view drawn with the true scale is called isometric drawing or
isometric view, while that drawn with the use of isometric scale is called isometric projection.
ENGINEERING DRAWING: To understand some of the hidden geometry of components an
imaginary plane is used to cut the object which is called _____________
a) auxiliary plane
b) picture plane
c) section plane
d) additional plane
Answer: c
Explanation: To understand some of the hidden geometry of components an imaginary plane is
used to cut the object which is called section plane or cutting plane. The new imaginary face
generated on the object is called the section.
ENGINEERING DRAWING: A sphere is cut by a plane which is inclined to both reference planes
the top view and front view of section will be ____________
a) line, line
b) circle, circle
c) ellipse, circle
d) ellipse, ellipse
Answer: d
Explanation: When a sphere is cut by a plane, the true shape of the section is always a circle. But
here it is asked view so they will be definitely ellipse since the section plane is inclined to both the
reference planes.
ENGINEERING DRAWING: In Dimensioning Rules, add ________________ before decimal point when
dimensioning figures with value less than one.
a. None
b. One
c. Significant Value
d. Zero
d. Zero
ENGINEERING DRAWING: In Dimensioning Rules, Dimensioning must be at ____ side only.
a. Right c. Bottom
b. Left d. Top
a. Right
In which system of dimensioning the figures can read from the bottom as well as right hand
side of the drawing?
a) Aligned system
b) Unidirectional system
c) Nonaligned multidirectional system
d) Parallel system
a) Aligned system
Answer: a
Explanation: In an aligned system of dimensioning, the dimension figures are written in such a
way that they can read from the bottom and right hand side of the drawing. It increases the
effort in reading the dimensions.
In which system of dimensioning the figures can read from the bottom only?
a) Aligned system
b) Unidirectional system
c) Nonaligned multidirectional system
d) Parallel system
Answer: b
Explanation: In unidirectional system of dimensioning, the dimension figures are so written that
they can be read only when viewed from the bottom and not from any other direction. Reading
the dimensions is easier than in aligned system.
Which is the wrong statement regarding dimensions?
a) Every dimension must be given, but none should be given more than once
b) Every dimension should be written to the left side of the drawing
c) Dimensions should be placed outside the views
d) A centre line should not be used as a dimension line
b) Every dimension should be written to the left side of the drawing
Explanation: There is no such rule that the dimensions should be placed only on left side of drawing because it may not possible to represent every dimension only on left side. So, it is given flexibility that dimensions can be given any side of drawing but none should be given twice or
more.
STRUCTURES: A siding or partition wall is referred as_____.
a. Girder

STRENGTH OF MATERIALS: Slenderness ratio is defined as ______.
a. Unsupported length over minimum radius of gyration
b. Unsupported length over maximum radius of gyration
c. Supported length over minimum radius of gyration
d. Supported length over maximum radius of gyration
a. Unsupported length over minimum radius of gyration

b. Grit #18
c. Grit #10
d. Grit #14
b. Grit #18

b. 2.5 m2
c. 2.0 m2
d. 3.5 m2
b. 2.5 m2

parcel without the mass of the water vapor included.
a. Relative Humidity
b. Specific Humidity
c. Mixing ratio
d. Absolute Humidity
b. Specific Humidity

a. Eddy currents
b. Hysteresis
c. Magnetic Field
d. Eddy currents and Hysteresis

corroded wire connection)
a. No surge current protection
b. High current flowing (high ampacity)
c. Low resistance (decreased resistance)
d. High voltage flowing
b. High current flowing (high ampacity)

WASTE MANAGEMENT: Estimate the biogas production in cubic meters per day from a large
balloon type digester using 1:1 water-manure ratio. The source farm has 1,000 heads of porkers of
mixed ages. Use a retention period of 30 days. The mean daily manure production of porkers is 2.2
kg/head while the specific gas production for 30-day manure retention period is 0.063 m3/kg.
WASTE MANAGEMENT: How many heads of breeding cattle are needed as source of manure to
generate 75 m3 of biogas a day if the retention period is 25 days and water-manure ratio is 1:1.
The mean daily manure production of breeding cattle is 13 kg/head while its specific gas
production for 25-day manure retention period is half of that of chicken dung.
