Question 7

A specific compound with the formula $A_{2}B_{3}$ crystallizes in an HCP lattice. Determine which atom constitutes the lattice and the fraction of tetrahedral voids occupied by the other atom.

Lattice: A; $\frac{2}{3}$ of Tetrahedral voids occupied by B
Lattice: A; $\frac{1}{3}$ of Tetrahedral voids occupied by B
Lattice: B; $\frac{2}{3}$ of Tetrahedral voids occupied by A
Lattice: B; $\frac{1}{3}$ of Tetrahedral voids occupied by A✔️

Correct Answer Logic:

In an HCP lattice, if there are $n$ atoms of B, the number of tetrahedral voids is $2n$. In the formula $A_2B_3$, the ratio of $A:B$ is $2:3$, which can be written as $\frac{2}{3}:1$. If B forms the lattice ($n$ atoms), then A occupies $2/3$ atoms. The fraction of tetrahedral voids occupied by A is $\frac{\text{atoms of A}}{\text{total tetrahedral voids}} = \frac{2/3}{2} = \frac{1}{3}$.

Mathematics QUESTION #6027

Question 16

For $x\in\left(0,\dfrac{1}{4}\right)$, the derivative of $\tan^{-1}\!\left(\dfrac{6x\sqrt{x}}{1-9x^3}\right)$ equals $\sqrt{x}\cdot g(x)$. Find $g(x)$.

$\dfrac{9}{1+9x^3}$✔️
$\dfrac{3x\sqrt{x}}{1-9x^3}$
$\dfrac{3x}{1-9x^3}$
$\dfrac{3}{1+9x^3}$

Correct Answer Logic:

Write $\frac{6x\sqrt{x}}{1-9x^3} = \frac{2\cdot3x^{3/2}}{1-(3x^{3/2})^2}=\frac{2t}{1-t^2}$ where $t=3x^{3/2}$.

So $\tan^{-1}\!\left(\frac{2t}{1-t^2}\right)=2\tan^{-1}(t)=2\tan^{-1}(3x^{3/2})$

Differentiate: $\frac{d}{dx}[2\tan^{-1}(3x^{3/2})] = \frac{2}{1+9x^3}\cdot 3\cdot\frac{3}{2}x^{1/2} = \frac{9\sqrt{x}}{1+9x^3}$

Since this equals $\sqrt{x}\cdot g(x)$: $g(x)=\dfrac{9}{1+9x^3}$

Civil / Architecture QUESTION #2374

Question 19

In the Pushover Analysis (nonlinear static analysis) for seismic performance evaluation, the Performance Point is determined as the intersection of:

The capacity spectrum (pushover curve in ADRS format) with the linear elastic response spectrum
The capacity spectrum with the demand spectrum (reduced for ductility using a constant ductility reduction factor), representing the actual inelastic seismic demand on the structure✔️
The base shear–roof displacement curve with the design base shear calculated by the Equivalent Lateral Force method
The demand spectrum at 5% damping with the elastic first-mode capacity

Correct Answer Logic:

In ATC-40 Capacity Spectrum Method (CSM), the Performance Point is the intersection of the Capacity Spectrum (pushover curve converted to ADRS — Acceleration-Displacement Response Spectrum format: Sa vs. Sd) with the Demand Spectrum (elastic 5%-damped spectrum reduced by effective damping $\beta_{eff}$ accounting for hysteretic energy dissipation). This point represents the actual expected displacement demand on the inelastic structure for the given earthquake.
