Mechanical Engineering QUESTION #2544

Question 3

The magnitude of the cross product $\mathbf{A}\times\mathbf{B}$ equals:

The area of the triangle formed by $\mathbf{A}$ and $\mathbf{B}$
The area of the parallelogram formed by $\mathbf{A}$ and $\mathbf{B}$✔️
The volume of the parallelepiped formed by $\mathbf{A}$ and $\mathbf{B}$
The scalar projection of $\mathbf{A}$ onto $\mathbf{B}$

Correct Answer Logic:

By definition, $|\mathbf{A}\times\mathbf{B}|=|A||B|\sin\theta$, which equals the area of the parallelogram spanned by the two vectors. The area of the triangle is half this value.

Question 5

Correct antonym of "MORATORIUM" is

Large tomb
Waiting period✔️
Security for debt

Civil Engineering QUESTION #2126

Question 7

The hydraulic grade line (HGL) and energy grade line (EGL) in pipe flow are related such that:

HGL is always above EGL by the velocity head
EGL is always above or equal to HGL by the velocity head $\dfrac{V^2}{2g}$ — the vertical distance between EGL and HGL equals the velocity head at any cross-section✔️
HGL and EGL coincide for all flows
EGL slopes upward in the direction of flow while HGL slopes downward

Correct Answer Logic:

EGL represents total energy head $= \dfrac{p}{\rho g} + z + \dfrac{V^2}{2g}$. HGL represents piezometric head $= \dfrac{p}{\rho g} + z$. The difference is the velocity head: $EGL - HGL = \dfrac{V^2}{2g}$. Both slope downward in flow direction (energy loss). EGL is always above HGL (except at stagnation). When HGL falls below pipe centerline, pressure becomes sub-atmospheric — risk of cavitation and column separation.

Electrical Engineering QUESTION #2189

Question 14

A p-channel JFET has $I_{DSS} = -8\,\text{mA}$ and pinch-off voltage $V_P = +3\,\text{V}$. At $V_{GS} = 1.5\,\text{V}$ (saturation region), the drain current $I_D$ is:

$-2\,\text{mA}$✔️
$-4\,\text{mA}$
$-6\,\text{mA}$
$+2\,\text{mA}$

Correct Answer Logic:

$I_D = I_{DSS}\!\left(1-\frac{V_{GS}}{V_P}\right)^2 = -8\!\left(1-\frac{1.5}{3}\right)^2 = -8\times(0.5)^2 = -8\times0.25 = -2\,\text{mA}$. Negative sign confirms conventional current flows from source to drain in p-channel device.
