If ‘W’ is the load on a circular slab of radius ‘R’, the maximum radial moment at the centre of the slab, is

WR²/16

2WR²/16

5WR²/16

3WR²/16

TRUE ANSWER : ?
YOUR ANSWER : ?

If the maximum shear stress at the end of a simply supported R.C.C. beam of 16 m effective span is 10 kg/cm², the length of the beam having nominal reinforcement, is

8 cm

10 cm

12 cm

6 cm

TRUE ANSWER : ?
YOUR ANSWER : ?

An R.C.C. beam not provided with shear reinforcement may develop cracks in its bottom inclined roughly to the horizontal at

35°

55°

25°

45°

TRUE ANSWER : ?
YOUR ANSWER : ?

If A is the area of the foundation of a retaining wall carrying a load W and retaining earth of weight 'w' per unit volume, the minimum depth (h) of the foundation from the free surface of the earth, is

h = (W/Aw) [(1 + sin φ)/(1 + sin φ)]

h = (W/Aw) [(1 - sin φ)/(1 + sin φ)]²

h = √(W/Aw) [(1 - sin φ)/(1 + sin φ)]²

h = (W/Aw) [(1 - sin φ)/(1 + sin φ)]
