Q9. 10 divisions of verniers scale are equal to 11 division of a main scale of each 0.1 mm. what is the least count of the verniers scale?
Q10. A dry soil has mass specific gravity of 1.35. If the specific gravity of solids is 2.7 then the void ratio will be
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.
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
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
G = 2.60
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
Sol. The shrinkage limit is the water content where further loss of moisture will not result in any volume reduction.
R = 230 m
V = 80 kmph
