(d) Shrinking

Q2. Piezometer is used to measure:
(a) Pressure in pipe, channels etc.
(b) Atmospheric pressure
(c) Very low pressure
(d) Difference of pressure between two points

Q3. The longitudinal stress in a thin (thickness) cylinder pressure vessel of diameter d and internal pressure, p is
(a) pd/t
(b) pd/2t
(c) pd/4t
(d) pd/8t

Q4. Influence line diagrams can be drawn for
(a) Only beams
(b) Beams arches, trusses etc.
(c) Only arches
(d) Only trusses

Q5. Minimum reinforcement in circular concrete column as per IS – 456 is –
(a) 4 bars of 12 mm
(b) Greater 0.80% of cross – sectional area 4 bars of 12 mm
(c) 6 bars of 12 mm
(d) Greater of 0.80% of cross – sectional area and 6 bars of 12 mm

Q6. Which one of the following would help prevent the escape of foul sewer gases from a water closet?
(a) Vent pipe
(b) Gully trap
(c) Air gap
(d) None of these


S1. Ans.(c)
Sol. Segregation→ Separation of coarse aggregates from mortar during transportation is called segregation. Due to segregation voids in concrete increased and strength of concrete decreased.

S2. Ans.(c)
Sol. Piezometer is a device which is used to measure low pressure it can only measure pressure of liquid only and not able to measure for gas. It could not able to measure pressure below ambient I.e., vacuum pressure.

S3. Ans.(c)
Sol. In a thin cylindrical pressure vessel,
Longitudinal stress (σ_l )=pd\/4t
Circumferential (Hoop) stress, (σ_h )=pd\/2t

S4. Ans.(b)
Sol. The influence line diagram is the graphical representation for reaction, shear force and bending moment due to moving load. It can be drawn for beams, arches, trusses etc.

S5. Ans.(d)
Sol. → Minimum % reinforcement in column = 0.8% of gross area
→ Maximum % reinforcement = 4% of gross area (if bars are lapped)
→ 6% of gross area (it bars are not lapped)
→ No. of bars in circular column equal to ‘6’
→ No. of bars in rectangular column equal to ‘4’

S6. Ans.(d)
Sol. Intercepting trap is used to prevent entry of foul sewer gases into the water closet by providing a water seal.
