Q6. Examine the test arrangement and the soil properties given below :

The maximum pressure that can be applied with a factor of safety of 3 through the concrete block, ensuring no bearing capacity failure in soil using Terzaghi’s bearing capacity equation without considering the shape factor, depth factor and inclination factor is
Answer : Option A
Explaination / Solution:
No Explaination.


Q7. The values of axial stress (σ) in kN/m2 , bending moment (M) in kNm, and shear force (V) in kN acting at point P for the arrangement shown in the figure are respectively
 
Answer : Option B
Explaination / Solution:

Loading after removing of cable 
Axial stress = 50/(0.2×0.2) = 1250kN/m2
B.M = 50 × 3 = 150kNm
S.F = 50kN
