(a) 6 × 90°
(b) 4 × 90°
(c) 6 × 180°
(d) 5 × 90°
Q2. A clay has unconfined compressive strength of 200 kN/sq m in undisturbed state. The clay was then remolded and the unconfined compressive strength was found to be 60 kN/sq m. the sensitivity of this clay is:
(a) 0.30
(b) 3.33
(c) 2.33
(d) 1.68

(a) d×t×f_b
(b) 2d×t×f_b
(c) 2×d²×t×f_b
(d) None of the above

(a) 0.15 m
(b) 0.60 m
(c) 1.25 m
(d) 0.75 m
Q5. The specific gravity of bitumen
(a) 0.8
(b) 0.9
(c) 2.02
(d) 1.02
Q6. Which of the following area is/are NOT included in the Carpet area?
(a) The walls along with doors and other openings
(b) All of the options
(c) Entrance gate
(d) Verandah, corridor and passage
Solutions
S1. Ans.(a)
Sol. If n is the no. of sides of a closed traverse, then total sum of interior will be = (2n – 4) × 90°
n = no. of sides
In Question, Pentagon is given, hence (n) = 5
Sum of interior angle = (2 × 5 – 4) × 90° = 6 × 90°
S2. Ans.(b)
Sol. Sensitivity=(Unconfined compressive strength)undisturbed/(Unconfined compressive strength)remoulded
Sensitivity=200/60=3.33
S3. Ans.(a)
Sol. Bearing strength of rivet joint
(d×t×σ_bp )
σ_bp→ permissible bearing stress in rivet.
S4. Ans.(d)
Sol.
Discharge (m³/sec.) | Freeboard (m.) |
1 to 5 | 0.50 |
5 to 10 | 0.60 |
10 to 30 | 0.75 |
30 to 150 | 0.90 |
S5. Ans.(d)
Sol. The specific gravity of bitumen is 0.97– 1.02.
S6. Ans.(b)
Sol. Carpet area does not include wall area, doors and other openings area, verandah, corridor and passage area and entrance gate.
