## RCC Structures Design The angle of repose of a soil is the maximum angle which the outer face of the soil mass makes

With the perpendicular to the inclined plane of the soil
With the horizontal
None of these
With the vertical

## RCC Structures Design The minimum thickness of a flat slab is taken

L/36 for end panels without drops
L/32 for end panels without drops
All listed here
L/36 for interior panels without drop

l = dt/4Sb
l = dt/Sb
l = dt/3Sb
l = dt/2Sb

## RCC Structures Design If p1 is the vertical intensity of pressure at a depth h on a block of earth weighing w per unit volume and the angle of repose φ, the lateral intensity of pressure p2 is

w (1 - cos φ)/h (1 + sin φ)
wh (1 - sin φ)/(1 + sin φ)
wh (1 - cos φ)/(1 + sin φ)
wh (1 - tan φ)/(1 + tan φ)
