Architecture QUESTION #2363

Question 5885

In the analysis of indeterminate structures using the Flexibility (Force) Method, the compatibility equation for a structure with $n$ redundants is expressed in matrix form as:

$[F]\{X\} = \{D_0\}$
$[K]\{D\} = \{P\}$
$[F]\{X\} + \{D_0\} = \{0\}$✔️
$[K]\{X\} = -\{D_0\}$

Correct Answer Logic:

The compatibility equation in the Force Method is $[F]\{X\} + \{D_0\} = \{0\}$ (or equivalently $[F]\{X\} = -\{D_0\}$), where $[F]$ is the flexibility matrix (flexibility coefficients $f_{ij}$ = displacement at $i$ due to unit force at $j$), $\{X\}$ is the vector of redundants, and $\{D_0\}$ is the displacement vector of the released structure (primary structure) under applied loads. Option B is the stiffness method equation.

The following text is from Ezra Pound's 1909 poem "Hymn III," based on the work of Marcantonio Flaminio. As a fragile and lovely flower unfolds its gleaming foliage on the breast of the fostering earth, if the dew and the rain draw it forth; / So doth my tender mind flourish, if it be fed with the sweet dew of the fostering spirit, / Lacking this, it beginneth straightway to languish, even as a floweret born upon dry earth, if the dew and the rain tend it not. Based on the text, in what way is the human mind like a flower?

It becomes increasingly vigorous with the passage of time.
It draws strength from changes in the weather.
It requires proper nourishment in order to thrive.✔️

Gardner's theory proposes 8–9 multiple intelligences; Spearman proposed g-factor and s-factors; Cattell-Horn-Carroll distinguishes fluid and crystallized intelligence.

Civil Procedure QUESTION #3716

Question 5899

A high-end electronics store mistakenly advertises a $\text{\$2,000}$ TV for $\text{\$200}$ on its website. A customer buys 10 of them. The store realizes the error and cancels the order. The customer sues. Is the store bound by the $\text{\$200}$ price?

Yes, an advertisement is always a binding offer.
No, because an advertisement is generally an invitation to deal, not an offer.✔️
Yes, because the customer accepted the offer by clicking 'buy.'
No, because of the doctrine of mutual mistake.

Correct Answer Logic:

Generally, advertisements are invitations for offers, not offers themselves. Even if treated as an offer, a 'unilateral mistake' where the other party knew or should have known of the error (buying 10 for 10% of the value) allows for rescission.

Physics QUESTION #989

Question 5900

An electron projected perpendicular to a uniform magnetic field $B$ moves in a circle. If Bohr's quantization is applicable, then the radius of the electronic orbit in the first excited state is:

$\sqrt{\dfrac{h}{\pi eB}}$✔️
$\sqrt{\dfrac{2h}{\pi eB}}$
$\sqrt{\dfrac{h}{2\pi eB}}$
$\sqrt{\dfrac{4h}{\pi eB}}$

Correct Answer Logic:

By Bohr quantization: $mvr = \frac{nh}{2\pi}$. For circular motion in $B$: $mv = eBr$. So $eBr^2 = \frac{nh}{2\pi} \Rightarrow r = \sqrt{\frac{nh}{2\pi eB}}$. First excited state: $n=2$ gives $r=\sqrt{\frac{2h}{2\pi eB}}=\sqrt{\frac{h}{\pi eB}}$.
