Time: 8 Minutes

Q1. A vertical plate of a plate girder is called
(a) Web plate
(b) Flange plate
(c) Cover plate
(d) None of these

Q2. An aggregate is said to be flaky if its least dimension is less than …………….
(a) 1/5th of mean dimension
(b) 2/5th of mean dimension
(c) 3/5th of mean dimension
(d) 4/5th of mean dimension

Q3. If the Froude number of a hydraulic jump is more than 9, this jump is classified as –
(a) Weak jump
(b) Strong jump
(c) Oscillating jump
(d) None of these

Q4. A circular shaft can transmit a torque of 5 kNm. If the torque is reduced to 4 kNm, then the maximum value of bending moment that can be applied to the shaft is
(a) 1 kNm
(b) 2 kNm
(c) 3 kNm
(d) 4 kNm

Q5. A line joining some fixed points on the main survey lines, is called a
(a) Check line
(b) Tie line
(c) Base line
(d) None of these

Q6. In absence of detailed design, the percentage for steel concrete may be taken approximately for beams is
(a) 0.7% to 1.0%
(b) 1.0% to 2.0%
(c) 1.0% to 5.0%
(d) 0.5% to 0.8%

Solutions

S1. Ans.(a)
Sol. A vertical plate of a plate girder is called web plate. The thickness and depth of web plate depends upon bending moment and shear stress acting on the plate.

S2. Ans.(c)
Sol. An aggregate is said to be flaky it the percentage of particle having their least size smaller than 3/5th of their mean dimension.

S3. Ans. (b)
Sol. Classification of hydraulic jump –

 Jump Froude Number Undular Jump 1 to 1.7 Weak Jump 1.7 to 2.5 Oscillating Jump 2.5 to 4.5 Steady Jump 4.5 to 9 Strong Jump > 9

S4. Ans.(c)
Sol. T_e=5 KN.m.
T= 4 KN.m
M= ?
Equivalent Torque (Te) = √(T^2+M²)
5=√(4^2+M²)
M= 3 KN.m

S5. Ans.(b)
Sol. Lines used in surveying →
Main line → These lines connect main stations also called survey line or chain line.
Check line → It is used to check the accuracy of work.
Base line → It is the biggest central line which divide the whole area into two parts.
Tie line → It is used for detailing of features or nearby objects in area and join some fixed points on the main survey line.

S6. Ans.(b)
Sol. In the absence of detailed design, the percentage of steel is taken as-
– In case of raft foundation → 0.5% to 0.8%
– In case of slab → 0.7% to 1.0%
– In case of beam → 1.0% to 2.0%
– In case of column → 1.0% to 5.0%
