Mechanical Engineering QUESTION #2447

Question 2729

The Duhamel integral gives the response of an undamped SDOF system to an arbitrary forcing function $F(t)$ as:

$x(t) = \frac{1}{m\omega_n}\int_0^t F(\tau)\sin[\omega_n(t-\tau)]\,d\tau$ plus homogeneous solution✔️
$x(t) = \frac{1}{k}\int_0^t F(\tau)\,d\tau$
$x(t) = \int_0^t F(\tau)\cos[\omega_n(t-\tau)]\,d\tau$
$x(t) = F(t)/k$

Correct Answer Logic:

The Duhamel (convolution) integral for an undamped SDOF system: $x(t)=\frac{1}{m\omega_n}\int_0^t F(\tau)\sin[\omega_n(t-\tau)]d\tau$ plus the free-vibration homogeneous solution from initial conditions.

Basic Mathematics QUESTION #4520

Question 2730

What is $\sqrt{\frac{25}{9}}$?

$\frac{5}{3}$✔️
$\frac{25}{9}$
$\frac{5}{9}$
$\frac{2.5}{3}$

Correct Answer Logic:

$\sqrt{\frac{a}{b}} = \frac{\sqrt{a}}{\sqrt{b}}$. So $\sqrt{\frac{25}{9}} = \frac{\sqrt{25}}{\sqrt{9}} = \frac{5}{3}$

Mechanical Engineering QUESTION #2536

Question 2731

A force $\mathbf{F} = 3\hat{i} + 4\hat{j}$ N acts at point $P(2,\,1,\,0)$ m. The moment vector about the origin is:

$5\hat{k}$ N·m✔️
$-5\hat{k}$ N·m
$8\hat{k}$ N·m
$2\hat{k}$ N·m

Correct Answer Logic:

Moment $\mathbf{M}=\mathbf{r}\times\mathbf{F}=(2\hat{i}+\hat{j})\times(3\hat{i}+4\hat{j})$. Cross product: $(2\cdot4-1\cdot3)\hat{k}=(8-3)\hat{k}=5\hat{k}$ N·m.

Paper-I (Anatomy/Physiology and Biochemistry/Microbiology) QUESTION #3299

Question 2733

'Active Immunity' differs from 'Passive Immunity' because it involves:

Injection of pre-formed antibodies
The body's own production of antibodies and memory cells✔️
A short duration of protection
No immune response

Correct Answer Logic:

Active immunity is slower to develop but provides long-lasting protection.

Physics QUESTION #1027

Question 2734

The current passing through the battery in the given circuit (5V source with complex resistor network including $1.5\Omega, 5\Omega, 2.5\Omega, 5.5\Omega, 6\Omega, 3\Omega, 1.5\Omega, \frac{1}{3}\Omega$):

2.5 A
1.5 A
2.0 A✔️
0.5 A

Correct Answer Logic:

Analysing the circuit by combining resistors: the network simplifies to a total resistance of $2.5\ \Omega$ across the 5V battery. Current $= \frac{5}{2.5} = 2.0\ \text{A}$.

Economics QUESTION #1702

Question 2738

The Agreement on Agriculture (AoA), negotiated under the Uruguay Round and administered by the WTO, has its primary regulatory scope directed at which domain of member countries' policies?

Industrial tariff structures and non-tariff barriers to manufactured goods
General export licensing and quota allocation regulations
Disciplines on domestic agricultural support, export subsidies, and market access commitments✔️
None of these

Correct Answer Logic:

The WTO Agreement on Agriculture (AoA) operates across three pillars: (1) Market Access — reduction of tariffs and elimination of non-tariff barriers on agricultural imports; (2) Domestic Support — disciplines on production-distorting subsidies (Amber Box, Blue Box, Green Box); and (3) Export Competition — reduction and elimination of export subsidies. It does not primarily regulate industrial or general export policy.

Civil Engineering QUESTION #2125

Question 2739

Bernoulli's equation for steady, incompressible, inviscid flow along a streamline is $\dfrac{p}{\rho g} + \dfrac{V^2}{2g} + z = \text{constant}$. The term $\dfrac{V^2}{2g}$ represents:

Pressure head
Velocity head (kinetic energy per unit weight of fluid)✔️
Elevation head
Total energy head

Correct Answer Logic:

In Bernoulli's equation, each term has units of length (head): $\dfrac{p}{\rho g}$ = pressure head; $\dfrac{V^2}{2g}$ = velocity head (kinetic energy per unit weight); $z$ = elevation (potential energy per unit weight); total = piezometric + velocity head = total energy head. Velocity head represents kinetic energy — it converts to pressure head at stagnation points (Pitot tube principle).

Mathematics QUESTION #4092

Question 2740

The solution set of the inequality $x^2+x>2$ is:

$(-2,1)$
$(-\infty,-2)\cup(1,\infty)$✔️
$[-2,1]$
$(-1,2)$

Correct Answer Logic:

Factor: $x^2+x-2=(x+2)(x-1)>0$. Product of two factors is positive when both are positive ($x>1$) or both are negative ($x<-2$). Solution: $(-\infty,-2)\cup(1,\infty)$.
