Civil Engineering QUESTION #6622

Question 1782

When checking for 'Web Local Yielding' in a beam, the load is assumed to distribute from the outer surface of the flange at a slope of:

1:01
01:02.5
1:05✔️
2.5:1

Correct Answer Logic:

AISC assumes that a concentrated load applied to a flange spreads out at a 1:2.5 slope (1 horizontal for 2.5 vertical). Therefore, the length of the web resisting yielding at the toe of the fillet is $N + 5k$ (for interior loads).

Constitutional Law QUESTION #5834

Question 1784

The President orders the Secretary of Commerce to take over all domestic steel mills to ensure production during a national labor strike, citing his powers as Commander in Chief. Congress has not authorized this action. Is the order valid?

Yes, because the President has inherent 'emergency powers' to protect the economy.
Yes, because the President is the Commander in Chief and steel is necessary for defense.
No, because the President’s power is at its 'lowest ebb' when acting against the implied or express will of Congress.✔️
No, because the 5th Amendment prohibits the taking of private property without just compensation.

Correct Answer Logic:

In Youngstown Sheet & Tube Co. v. Sawyer, the Court held that the President cannot use his Commander in Chief powers to seize domestic private property during a labor dispute without congressional authorization.

Civil Procedure QUESTION #3696

Question 1785

A plaintiff (State A) sues a defendant (State B) in federal court. The defendant believes the court lacks personal jurisdiction. The defendant files a motion to dismiss under Rule 12(b)(2). The court denies the motion. The defendant then participates in the trial and loses. On appeal, the defendant raises the personal jurisdiction issue. What is the likely result?

The issue is waived because the defendant participated in the trial.
The appellate court will review the issue because the defendant preserved it by making a timely motion.✔️
The issue is waived because the defendant did not file an interlocutory appeal immediately after the denial.
Personal jurisdiction is never reviewable on appeal.

Correct Answer Logic:

By making a timely Rule 12(b)(2) motion, the defendant preserved the objection. Unlike some state courts, federal procedure does not require a party to 'stand on the motion' and refuse to defend on the merits to preserve the jurisdictional objection for appeal.

Question 1787

In the decimal system (base-10), which statement is CORRECT?

You can use digits 0 through 8 only (9 digits total)
You can use digits 0 through 9 (10 digits total)✔️
You can use digits 1 through 10 (10 digits total)
You can use digits 0 through 10 (11 digits total)

Correct Answer Logic:

In the decimal system, there are exactly 10 possible digit symbols ranging from zero (0) to nine (9). The number 10 itself is NOT a single digit — it is composed of two digits (1 and 0). This is why the system is called 'base-10'.

Dairy Food Science and Technology QUESTION #5958

Question 1790

The Milk to Acid to Amyl Alcohol ratio in the standard Gerber test is:

$10\;\text{mL}$ milk : $5\;\text{mL}\;\text{H}_2\text{SO}_4$
$11\;\text{mL}$ milk : $10\;\text{mL}\;\text{H}_2\text{SO}_4$ : $1\;\text{mL}$ amyl alcohol✔️
$10\;\text{mL}$ milk : $1\;\text{mL}$ amyl alcohol only
$1\;\text{mL}$ milk : $10\;\text{mL}\;\text{H}_2\text{SO}_4$

Correct Answer Logic:

Standard Gerber method: $10\;\text{mL}\;\text{H}_2\text{SO}_4$ ($d = 1.820\text{–}1.825\;\text{g/mL}$) $+ 11\;\text{mL}$ milk $+ 1\;\text{mL}$ amyl alcohol in a Gerber butyrometer. The acid dissolves all milk components except fat. Centrifugation separates fat into the graduated neck for direct volumetric reading ($\%$ fat).

Civil Procedure QUESTION #3689

Question 1791

A plaintiff (State A) sues a defendant (State B) for $\text{\$80,000}$ in federal court. The defendant impleads a third-party (State A) for indemnity under Rule 14. The plaintiff then amends the complaint to assert a $\text{\$50,000}$ claim directly against the third-party defendant. Does the court have jurisdiction over the plaintiff's new claim?

Yes, under supplemental jurisdiction because it arises from the same nucleus of fact.
No, because 28 U.S.C. $\S 1367(b)$ bars supplemental jurisdiction for claims by plaintiffs against persons made parties under Rule 14 in diversity cases.✔️
Yes, because the total amount in controversy is now $\text{\$130,000}$.
No, because the claim against the third-party is for less than $\text{\$75,000}$.

Correct Answer Logic:

In cases founded solely on diversity, 28 U.S.C. $\S 1367(b)$ excludes supplemental jurisdiction over claims by plaintiffs against persons made parties under Rule 14 (impleader) if it would be inconsistent with the requirements of diversity jurisdiction (complete diversity).
