B. Diagonal scale
C. Both A and B
D. None of the above
View Answer
Ans : B
Explanation: Diagonal scale is an engineering measuring instrument which is composed of a set of parallel straight lines which are obliquely crossed by another set of straight lines.
Question 2
Diagonal scale is used in engineering to read lengths with higher accuracy as it represents a unit into _________ different multiple.
A. one
B. two
C. three
D. four
View Answer
Ans : C
Explanation: Diagonal scale is used in engineering to read lengths with higher accuracy as it represents a unit into three different multiple in metres, centimeters and millimeters.
Question 3
If a diagonal scale is to be made with a meter, decimeter and centimeter then, how many divisions it has to be made vertically?
A. 3
B. 5
C. 7
D. 10
View Answer
Ans : D
Explanation: Vertical divisions are related to how many centimeters take a decimeter. It is 10. Or anywhere in a diagonal scales vertical division are dependent of 2nd and 3rd unit which we use in drawing diagonal scale
Question 4
Diagonal scales are used to measure small fractions of the unit of measurement
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: True, Diagonal scales are used to measure small fractions of the unit of measurement
Question 5
If a diagonal scale is to be made with a yard, feet and inch then, how many divisions it has to be made vertically?
A. 6
B. 12
C. 18
D. 24
View Answer
Ans : B
Explanation: Vertical divisions are related to how many inches take a foot. It is 12. Or anywhere in the diagonal scales vertical division are dependent of 2nd and 3rd unit which we use in drawing diagonal scale.
Question 6
Which of the following scales is used to accurately measure minute divisions?
A. Plain scale
B. Scale of chords
C. Comparative scale
D. Diagonal scale
View Answer
Ans : D
Explanation: Minute divisions are accurately measured by using diagonal scales. Diagonal scales are also when three different units of measurements are needed to be measured. With the help of these scales, we can get a relation between three different units
Question 7
Which of the following scales is used to accurately measure minute divisions?
A. Plain scale
B. Scale of chords
C. Diagonal scale
D. Comparative scale
View Answer
Ans : C
Explanation: Minute divisions are accurately measured by using diagonal scales. Diagonal scales are also when three different units of measurements are needed to be measured. With the help of these scales, we can get a relation between three different units
Question 8
A plot of 35,000 sq m is drawn on map as plot of 14 cm and 5 cm. Find the R.F.
A. 1/35000 cm
B. 1/34930 cm
C. 1/2236 cm
D. 1/50000 cm
View Answer
Ans : C
Explanation: Area of plot in drawing is 14 x 5 = 70 sq cm (equivalent to 35000 sq m). So 1 sq cm =35000/70 = 500 sq m. 1 cm = square root of 500 m = 22.3 m (equivalent to 1 cm). Representative fraction = 1/ (22.36 m) =1/ (2236 cm).
Question 9
Diagonal scale can measure more accurately than the plain scale.
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: True, Diagonal scale can measure more accurately than the plain scale.
Question 10
We can draw diagonal scale for meter, feet, inch.
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : B
Explanation: There exists a particular order in selecting 1st, 2nd and 3rd unit while drawing diagonal scale that is 1st should have a higher quantity of all three, 3rd should have least quantity of all three and 2nd should be middle in them. And there exits at least appreciable multiples among themselves.
