Civil Engineering QUESTION #2119

In the moment distribution method for analyzing indeterminate structures, the distribution factor (DF) for a member at a joint is defined as:

The ratio of the member stiffness to the sum of stiffnesses of all members meeting at the joint✔️
The ratio of the fixed-end moment in the member to the total applied moment at the joint
The carry-over factor multiplied by the member stiffness
The ratio of span length to total length of all members at the joint

Correct Answer Logic:

Distribution Factor $DF = \dfrac{K_{member}}{\sum K_{members\,at\,joint}}$, where $K = \dfrac{4EI}{L}$ for far-end fixed and $K = \dfrac{3EI}{L}$ for far-end pinned. The sum of DFs at any joint always equals 1.0 (except at fixed supports where DF = 0). The DF determines what fraction of the unbalanced moment is distributed to each member at a joint.

Physics QUESTION #7343

Question 1147

A projectile is launched from the ground with initial velocity $\vec{u} = u_0\hat{i} + v_0\hat{j}$. Gravity acts in the $-y$ direction. The maximum displacement in the $x$-direction is:

$\dfrac{u_0^2}{2g}$
$\dfrac{2u_0 v_0}{g}$✔️
$\dfrac{v_0^2}{2g}$
$\dfrac{4u_0 v_0}{g}$

Correct Answer Logic:

Time of flight $= \dfrac{2v_0}{g}$ (time for vertical displacement to return to zero).

Horizontal range $= u_0 \times \dfrac{2v_0}{g} = \mathbf{\dfrac{2u_0 v_0}{g}}$

Physics QUESTION #7332

Question 1150

A projectile is thrown at angles $(45°-\theta)$ and $(45°+\theta)$ with the horizontal. The ratio of their horizontal ranges is:

$1:1$✔️
$2:3$
$1:2$
$2:1$

Correct Answer Logic:

Using $R = \dfrac{u^2\sin2\alpha}{g}$:

$R_1 = \dfrac{u^2\sin(90°-2\theta)}{g} = \dfrac{u^2\cos2\theta}{g}$

$R_2 = \dfrac{u^2\sin(90°+2\theta)}{g} = \dfrac{u^2\cos2\theta}{g}$

$R_1 : R_2 = \mathbf{1:1}$

Question 1151

For external forced convection over a flat plate, the local Nusselt number in the laminar boundary layer region is given by:

$Nu_x = 0.332 \cdot Re_x^{1/2} \cdot Pr^{1/3}$✔️
$Nu_x = 0.023 \cdot Re_x^{0.8} \cdot Pr^{0.4}$
$Nu_x = Re_x \cdot Pr$
$Nu_x = 0.664 \cdot Re_x^{1/2} \cdot Pr^{1/3}$

Correct Answer Logic:

For laminar flow over a flat plate (local value): $Nu_x=0.332Re_x^{1/2}Pr^{1/3}$. Average over plate length $L$: $\overline{Nu}_L=0.664Re_L^{1/2}Pr^{1/3}$.

Question 1152

Casein can be industrially produced from skim milk by which method?

Centrifugal separation; used as a color in paints
Acid precipitation at $\text{pH}\;4.6$ (acid casein) or rennet coagulation (rennet casein), followed by washing, pressing, and drying; used in food products (cheese analogs, protein supplements) and non-food applications (adhesives, paper coating, textiles)✔️
Evaporation followed by spray drying; used as infant formula base
Microfiltration; used as a beverage protein supplement

Correct Answer Logic:

Casein production: skim milk $\rightarrow$ acid precipitation at $\text{pH}\;4.6$ or rennet treatment $\rightarrow$ whey drainage $\rightarrow$ washing (to remove lactose, minerals) $\rightarrow$ pressing $\rightarrow$ drying. Food uses: cheese analogs, protein supplements, coffee whiteners. Industrial uses: paper coating, adhesives, leather finishing.

Question 1155

A pipe open at both ends has fundamental frequency $f$. It is dipped to half its length in water. The new fundamental frequency is:

$\dfrac{3f}{2}$
2f
$\dfrac{f}{2}$
f✔️

Correct Answer Logic:

Original open pipe of length $L$: $f=\frac{v}{2L}$. When dipped to half length, remaining open length $=L/2$ acts as a closed pipe (one end closed by water). Fundamental of closed pipe: $f'=\frac{v}{4(L/2)}=\frac{v}{2L}=f$. The frequency remains $f$.

Chemistry QUESTION #5571

Question 1160

Arrange the following amines in increasing order of basicity: (a) vinylamine, (b) allylimine (secondary, =NH), (c) compound with $NH_2$ and $=NH$ groups, (d) $N$-methylamine

(b) < (a) < (d) < (c)✔️
(d) < (b) < (a) < (c)
(a) < (b) < (c) < (d)
(b) < (a) < (c) < (d)

Correct Answer Logic:

Basicity depends on electron availability on N. Imine-type N (sp² hybridized, as in =NH) is less basic than amine-type N (sp³). Among aliphatic amines, alkyl groups increase basicity. The increasing basicity order from the JEE 2018 question: (b) < (a) < (d) < (c), where the aliphatic secondary amine (c) is most basic.
