Civil Procedure QUESTION #3719

Question 6333

A painter agrees to paint a portrait for $\text{\$5,000}$, with payment due 'only if I am 100% satisfied with the likeness.' The painter does a high-quality job that meets all professional standards, but the client says, 'I just don't like it,' and refuses to pay. Can the painter recover?

Yes, if a 'reasonable person' would be satisfied with the portrait.
No, because satisfaction clauses regarding art/personal taste are governed by a subjective standard.✔️
Yes, because the client is acting in bad faith.
No, because the contract was an 'illusory promise.'

Correct Answer Logic:

For contracts involving personal taste or aesthetics (like a portrait), a 'satisfaction' clause is governed by a subjective standard. As long as the dissatisfaction is honest (not necessarily reasonable), the condition is not met.

Civil / Architecture QUESTION #2351

Question 6334

For the most hydraulically efficient (economical) trapezoidal open channel cross-section, the hydraulic radius $R$ at the optimal condition is related to the flow depth $y$ by:

$R = \dfrac{y}{4}$
$R = \dfrac{y}{2}$✔️
$R = y$
$R = 2y$

Correct Answer Logic:

For the most economical trapezoidal section, the condition is $R = y/2$ (hydraulic radius equals half the flow depth). This is equivalent to the condition that the channel can be inscribed in a semicircle of radius $y$. For a rectangular channel, the economical condition $b = 2y$ also yields $R = y/2$.

Boilers Mechanical Engineering QUESTION #2473

Question 6335

The tensile strength $S_{ut}$ of spring wire of diameter $d$ is estimated by the power law $S_{ut} = A/d^m$. For music wire, the exponent $m \approx 0.163$. This means:

Strength is independent of wire diameter
Strength INCREASES as wire diameter DECREASES (smaller wire is stronger)✔️
Strength increases as wire diameter increases
Strength is linearly proportional to wire diameter

Correct Answer Logic:

Since $S_{ut}=A/d^m$ with $m>0$, smaller diameter wire has higher tensile strength due to more cold-drawing and work-hardening effect.
