Question:-
Option (A)
keeping the width uniform and varying the depth
Option (B)
keeping the depth uniform and varying the width
Option (C)
varying the width and depth both
Option (D)
any one of the above
Correct Option:
D
Question:-
Option (A)
350 mm
Option (B)
400 mm
Option (C)
425 mm
Option (D)
600 mm
Correct Option:
C
Question Solution:
Pu = 1.5 x 1000 = 15000 kN
Pu = 0.4 fck x Ac + 0.67 fy x As
1500 x 103 = 0.4 x 20 (Ag - 0.01 Ag) + 0.67 x 415 x 0.01 Ag
therefore, Ag = 140180
= 140180
therefore, D = 425 mm
Question:-

Correct Option:
C
Question Solution:

Question:-
Option (A)
18.45 m
Option (B)
16.5 m
Option (C)
17.20 m
Option (D)
19.34 m
Correct Option:
D
Question Solution:
If the pressure at point P is p then
p-&γwghw1 + &γagha - &γwghw2 = (10.34 m x &γw x g)
=>
=> = 10.34
=> = 19.34 m
Question:-

Option (B)
ε(2 m - 1)
Option (C)

Option (D)

Whereε = linear strain, 1/m = Poisson's ratio
Correct Option:
C
Question Solution:
V = lbt and &δv = bt&δl + lt&δb + lb&δt

=
