S1. Ans.(d)
Sol. A fixed beam of span L, is subjected to a uniformly distributed load w per unit length. If beam has constant flexural rigidity, the fixed end moment is PL²/12.


S2. Ans.(b)
Sol. Gross diameter of a rivet is the diameter of rivet hole.
Nominal diameter (d) Gross diameter (d_o)
d ≤ 25 mm d_o = d + 1.5 mm
d > 25 mm d_o = d +2 mm
Dia. of rivet (d) = 20 mm
Dia. of hole (d_o)= 20 mm + 1.5 mm
d_o= 21.5 mm

S3. Ans.(a)
Sol. The Poisson’s ratio is a property of material which cannot be negative.
Poisson’s ratio in elastic range = 0.3
Poisson’s ratio in plastic range = 0.5

S4. Ans.(b)
Sol. Given,
γ_d=16 kN/m^3
γ_w=10 kN/m^3
G = 2.60
e= ?

S5. Ans.(b)
Sol. Uniformity coefficient (C_u) = D_60/D_10
If C_u≃1→ Uniformly graded soil
C_u>6→ Well graded sand
C_u>4→ Well graded gravel

S6. Ans.(a)
Sol. The shrinkage limit is the water content where further loss of moisture will not result in any volume reduction.

S7. Ans.(d)
Sol. Given,
γ_b=21 kN/m^3
γ_d=γ_b/(1+w)=21/(1+0.08)=19.44 kN/m^3

Sol. Given,
R = 230 m
V = 80 kmph
W_psy= ?

S9. Ans. (b)
