Solutions
S1. Ans.(c)
Sol. 1 km² = 1000 × 1000 m²
1 km² = 10,00,000 m²
S2. Ans.(d)
Sol. Terrazzo is small decorative chips embedded in cement paste. The chips may be of glass, marble etc. Along with chips, marble powder or magnesite powder is also added. A floor using 3-6 mm marble chips is known as terrazzo floor.
S3. Ans.(d)
Sol. Pressure (P) = ρ.gh
= 1000×9.81×1
= 9810 Pa.
S4. Ans.(c)
Sol. Bending moment equation
M/I=σ/y=E/R
Here,
M = bending moment
I = moment of inertia
σ = bending stress
y = distance from neutral axis
E = modulus of elasticity
R = Radius of curvature
S5. Ans.(c)
Sol. → Maximum diameter of main bars in slab equal to 10 mm.
→ Diameter of main bar ≯1/8× thickness of slab.
S6. Ans.(d)
Sol.
D_60=4mm
D_30=2mm
D_10=0.5mm
Coefficient of uniformity (C_u )=D_60/D_10
=4/0.5
=8
