If YY is the centroidal axis of a T-beam section subjected to plastic moment, MP, the neutral axis lies
-
Solution
The neutral axis will be nearer or inside the flage.
In a reinforce concrete beam column, the increase in the flexural strength along with increase in axial strength occurs
The contour integral \(\int_{c}e^{\frac{1}{z}}dz\) with C as the counterclockwise unit circle in the z-plane is equal to
-
Solution
The eigen values of \(\begin{bmatrix} 1 &1 &1 \\ 1 &1 &1 \\ 1 &1 &1 \end{bmatrix}\) are
-
Solution
Sum of eigen value =sum of diagonal elements= 3
∴ answer is either (c) or (d)
Product of eigen value= determinant of matrix
= 1 (1 – 1)– 1 (1 –1) + 1(1 – 1)
= 0
∴ Answer (c)
The ratio of actual evapo-transpiration to potential evapo-transpiration is in the range

Two samples of water A and B have pH values of 4.4 and 6.4 respectively. How many times more acidic sample A is than sample B?
-
Solution
Difference of pH = 6.4 – 4.4 = 2
Quantum of acidity = (10)2
= 100 times more acidic
