Q1. In a closed traverse pentagon, the sum of interior angles is equal to ___________.
(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

Q3. Bearing strength of single riveted lap joint is equal to:
(a) d×t×f_b
(b) 2d×t×f_b
(c) 2×d²×t×f_b
(d) None of the above

Q4. The minimum freeboard recommended for lined canal carrying discharge greater than 10 m³/s
(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.
