Distribution of shear intensity over a rectangular section of a beam, follows:
A. A circular curve
B. A straight line
C. A parabolic curve
D. An elliptical curve
If the shear stress in a R.C.C. beam is
A. Equal or less than 5 kg/cm2, no shear reinforcement is provided
B. Greater than 4 kg/cm2, but less than 20 kg/cm2, shear reinforcement is provided
C. Greater than 20 kg/cm2, the size of the section is changed
D. All the above
In a pre-stressed member it is advisable to use
A. Low strength concrete only
B. High strength concrete only
C. Low strength concrete but high tensile steel
D. High strength concrete and high tensile steel
In a simply supported slab, alternate bars are curtailed at
A. $${\frac{1}{4}^{{\text{th}}}}$$ of the span
B. $${\frac{1}{5}^{{\text{th}}}}$$ of the span
C. $${\frac{1}{6}^{{\text{th}}}}$$ of the span
D. $${\frac{1}{7}^{{\text{th}}}}$$ of the span
For Short column,
Span/Least lateral dimension < 12
but in case of long columns, it is > 12
For short column,
slenderness ratio is < 45
But in long column, it is > 45.
For short column,
Radius of gyration is MORE,
but in long columns, radius of gyration is LESS
For short column,
Loading failure is called- Crushing (due to compressive stress)
But in long column, failure is due to- Bulking or Crippling Load (due to Bulking stress).

isn't it less then 12?
How? Can you please give reference? Because it's less than 12 according to IS 456
