Question 5

What does 'primate city' phenomenon indicate in urban systems?

Equal distribution of city sizes
Dominance of one disproportionately large city✔️
Multiple cities of similar size
Declining urban population

Correct Answer Logic:

A primate city is disproportionately larger (typically 2+ times) than the second-largest city, dominating the urban system economically and politically. Common in developing countries, it often indicates centralized development and regional imbalances.

Question 6

The principal axes of a cross-section are axes about which:

The moment of inertia is maximum only
The product of inertia is zero AND the moments of inertia are extreme (max/min)✔️
The polar moment of inertia is minimum
All second moments are equal

Correct Answer Logic:

Principal axes are defined by two conditions: (1) $I_{xy}=0$ (product of inertia vanishes), and (2) the second moments $I_x$ and $I_y$ attain their absolute maximum and minimum values, called principal moments of inertia.

Question 8

Using only principal values of inverse functions, describe the set $A=\left\{x\geq0:\tan^{-1}(2x)+\tan^{-1}(3x)=\dfrac{\pi}{4}\right\}$.

Contains two elements
Contains more than two elements
Is a singleton✔️
Is an empty set

Correct Answer Logic:

Apply the addition formula: $\tan^{-1}(2x)+\tan^{-1}(3x)=\tan^{-1}\!\left(\dfrac{5x}{1-6x^2}\right)$ when $6x^2<1$.

Setting equal to $\pi/4$: $\dfrac{5x}{1-6x^2}=1 \Rightarrow 5x=1-6x^2 \Rightarrow 6x^2+5x-1=0$

$x=\dfrac{-5\pm\sqrt{25+24}}{12}=\dfrac{-5\pm7}{12}$

$x=\dfrac{2}{12}=\dfrac{1}{6}$ or $x=\dfrac{-12}{12}=-1$.

Since $x\geq0$, only $x=\dfrac{1}{6}$ is valid. Check: $6\cdot(1/6)^2=1/6<1$ ✓. So $A=\{1/6\}$ — a singleton.

Physics QUESTION #7016

Question 10

A hoop with radius $r$ and mass $m$ is rotating with an initial angular velocity $\omega_0$ and is placed on a rough horizontal floor. If the initial linear velocity of its center is zero, what will be the final linear velocity of the center when the hoop stops slipping and begins pure rolling?

$\frac{r\omega_0}{4}$
$\frac{r\omega_0}{3}$
$\frac{r\omega_0}{2}$✔️
$r\omega_0$

Correct Answer Logic:

Using the principle of conservation of angular momentum about the point of contact: $L_i = L_f$. Initial angular momentum $L_i = I \omega_0 = (mr^2) \omega_0$. Final angular momentum $L_f = I \omega + mrv = (mr^2)(\frac{v}{r}) + mrv = 2mrv$. Equating $mr^2\omega_0 = 2mrv$ gives $v = \frac{r\omega_0}{2}$.

Chemistry QUESTION #7116

Question 12

A $5.1\text{ g}$ sample of $NH_{4}SH$ is placed in a $3.0\text{ L}$ evacuated flask at $327^{\circ}C$. If $30\%$ of the solid decomposes into $NH_{3}(g)$ and $H_{2}S(g)$, find the $K_p$ for this reaction. ($R = 0.082\text{ L atm mol}^{-1}\text{ K}^{-1}$)

$0.242 \times 10^{-4} \text{ atm}^2$
$1 \times 10^{-4} \text{ atm}^2$
$4.9 \times 10^{-3} \text{ atm}^2$
$0.242 \text{ atm}^2$✔️

Correct Answer Logic:

Molar mass of $NH_4SH = 51\text{ g/mol}$. Initial moles $= 5.1/51 = 0.1\text{ mol}$.
At equilibrium, moles of $NH_3 = H_2S = 0.1 \times 0.3 = 0.03\text{ mol}$.
Using $PV = nRT$: $P_{NH_3} = P_{H_2S} = \frac{0.03 \times 0.082 \times 600}{3} = 0.492\text{ atm}$.
$K_p = P_{NH_3} \times P_{H_2S} = (0.492)^2 \approx 0.242\text{ atm}^2$.

Question 16

Which of the following parameters is used to categorize a steel section as 'compact' for flexure?

The ratio of flange width to thickness ($b/t$)✔️
The total depth of the beam ($d$)
The span-to-depth ratio ($L/d$)
The poisson's ratio ($\nu$)

Correct Answer Logic:

Compactness is a measure of a section's ability to develop its full plastic moment without local buckling. It is determined by checking the width-to-thickness ratios ($b/t$ for flanges, $h/t_w$ for webs) against limits $\lambda_p$.

Question 20

For an open kinematic chain with $n$ links forming a vector loop from point A to point B, the closure equation in scalar form (x-projection) is:

$\sum_{k=1}^{n} r_k\sin\phi_k = y_B - y_A$
$\sum_{k=1}^{n} r_k\cos\phi_k = x_B - x_A$✔️
$\prod_{k=1}^{n} r_k\cos\phi_k = x_B - x_A$
$\sum_{k=1}^{n} r_k = |r_B - r_A|$

Correct Answer Logic:

The vector loop equation projected onto the x-axis yields $\sum_{k=1}^n r_k\cos\phi_k = x_B - x_A$ and onto y gives $\sum_{k=1}^n r_k\sin\phi_k = y_B - y_A$.
