MCQs on Slope
1 - Question
Slope in the beam at any point is measured in ____________
a) Degrees
b) Minutes
c) Radians
d) Metric tonnes
View Answer
Answer: c
Explanation: The slope is defined as at any point on the bent beam is the angle measured in terms of radians to which the tangent at that point makes with the x axis.
Explanation: The slope is defined as at any point on the bent beam is the angle measured in terms of radians to which the tangent at that point makes with the x axis.
2 - Question
Elastic curve is also known as __________
a) Refraction curve
b) Reflection curve
c) Deflection curve
d) Random curve
View Answer
Answer: c
Explanation: An elastic curve is defined as the line to which the longitudinal axis of a beam deviates under given load. It is also called a deflection curve.
Explanation: An elastic curve is defined as the line to which the longitudinal axis of a beam deviates under given load. It is also called a deflection curve.
3 - Question
Which of the following method is not used for determining slope and deflection at a point?
a) Moment area method
b) Double integration method
c) Isoheytal method
d) Macaulay’s method
View Answer
Answer: c
Explanation: The method “Isoheytal” can be used for calculating run-off over an area. The remaining methods are effectively adopted to calculate the slope and deflection at a point in any type of beam.
4 - Question
The slope is denoted by _______
a) k
b) y
c) i
d) c
View Answer
Answer: c
Explanation: The slope at any section in a deflection beam is defined as the angle measured in radians to the tangent at the section makes with the original axis of the beam.
•It is denoted by “i”.
5 - Question
Calculate the slope at supports, if the area is 180kNm2. Take flexural rigidity as 50000.
a) 0.0054 radians
b) 0.0072 radians
c) 0.0036 radians
d) 0.108 radians
View Answer
Answer: c
Explanation: Maximum slope at supports be i = A/EI
= 180/50000
i = 0.0036 radians.
6 - Question
In cantilever beams, the slope is _____________ at fixed end.
a) Maximum
b) Zero
c) Minimum
d) Uniform
View Answer
Answer: b
Explanation: The slope in cantilever beam is zero at the fixed end of the cantilever and the slope is maximum at it’s free end. The slope is determined in the moment area method through Mohr’s theorems.
7 - Question
Slope is maximum at _______ in simply supported beams.
a) Mid span
b) Through out
c) Supports
d) At point of loading
View Answer
Answer: a
Explanation: In case simply supported beams, the slope is maximum at the end supports of the beam and relatively zero at midspan of a symmetrically loaded beam.
8 - Question
Mohr’s theorem- 1 states ________
a) E/AI
b) I/EA
c) A/EI
d) A=EI
View Answer
Answer: c
Explanation: According to Mohr’s theorem-1, the change of slope between any of the two points on and Elastic axis is equal to the net area of bending moment diagram (A) between these two points divided by flexural rigidity(EI).
9 - Question
Using Mohr’s theorem, calculate the maximum slope of a cantilever beam if the bending moment area diagram is 90kNm2. Take EI = 4000 kNm2.
a) 0.0225 radians
b) 0 0367 radians
c) 0.0455 radians
d) 0.066 radians
View Answer
Answer: a
Explanation: The maximum slope at free support (in cantilever beam) = i = A/EI
= 90/4000
= 0.0225 radians.
10 - Question
Contour canals are also called as ______
a) Single bank canal
b) Ridge canal
c) Side slope canal
d) Watershed canal
View Answer
Answer: a
Explanation: In this method, the canal is aligned along the falling contour. A generally higher side is left without bank. So it is also called a single bank canal. The contour canal cuts across the natural drainage courses.
11 - Question
______________ provides employment to the cultivators at the time of famine.
a) Productive canal
b) Link canal
c) Protective canal
d) Inundation canal
View Answer
Answer: c
Explanation: The construction of protective canals and their development may be started during summer in hence they provide employment to the farmers at the time of drought and famine. Protective canals are not remunerative as productive canals.
12 - Question
______________ bricks are used in the lining of blast furnaces.
a) Magnesia
b) Dolomite
c) Bauxite
d) Fly ash
View Answer
Answer: b
Explanation: Dolomite bricks are made especially from dolomite it contains nearly 30% lime and 22% of magnesium these bricks are inferior to magnesite bricks. They are generally used in the lining of blast furnaces.
13 - Question
_____________ bricks are resistant to corrosion.
a) silica bricks
b) magnesia bricks
c) bauxite bricks
d) fire bricks
View Answer
Answer: c
Explanation: Bauxite bricks contain nearly 75% of aluminium and it is mixed with fire clay 15 to 30% and added some water to mould. High alumina bricks are resistant to corrosion.
14 - Question
_____________ bricks are used in the lining of electric furnace.
a) Frosterite
b) Spinel
c) Chrome
d) Basic
View Answer
Answer: b
Explanation: The spinal bricks belong to neutral bricks. The spinel bricks mainly consist of alumina and magnesia. These bricks are widely used in the lining of electric furnace.
15 - Question
The finished product after burning magnesite is named as ___________
a) Perillax
b) Hellyx
c) Pyrolytaex
d) Syrilax
View Answer
Answer: a
Explanation: The heating of magnesia bricks is continued in the same kiln after reaching the temperature of 1950°C, and then some amount of iron oxide is mixed. The finished product after burning magnesite is named as perillax.
