QUESTION #2513
Question 1321
The Soderberg criterion for fatigue is more conservative than the modified Goodman criterion because it uses which strength in place of \(S_{ut}\)?
Correct Answer Logic:
The Soderberg criterion: \(\frac{\sigma_a}{S_e}+\frac{\sigma_m}{S_y}=\frac{1}{n}\). It substitutes yield strength \(S_y\) for ultimate strength \(S_{ut}\). Since \(S_y < S_{ut}\), the Soderberg line falls inside the Goodman line, making it more conservative.

Silicones are primarily:
Correct Answer Logic:
Silicones (polysiloxanes) are hybrid organic-inorganic polymers. Their backbone is inorganic — consisting of alternating silicon and oxygen atoms (\(\text{Si-O-Si}\) chains) — while organic groups (typically methyl or phenyl) are attached to silicon. This dual nature gives silicones unique properties: thermal stability, water repellence, and flexibility.

Question 1327
A magnetic moment of 2.83 BM is exhibited by which of the following ions? (At. nos: Ti = 22, Cr = 24, Mn = 25, Ni = 28)
Correct Answer Logic:
Formula: \(\mu = \sqrt{n(n+2)}\) BM, where \(n\) = number of unpaired electrons.
For \(\mu = 2.83\) BM: \(2.83 = \sqrt{n(n+2)}\) → \(n = 2\)
Checking \(\text{Ni}^{2+}\): Ni (Z=28) = [Ar] 3d⁸ 4s². \(\text{Ni}^{2+}\) = [Ar] 3d⁸ → 2 unpaired electrons → \(\mu = \sqrt{2 \times 4} = \sqrt{8} \approx 2.83\) BM ✓
For \(\mu = 2.83\) BM: \(2.83 = \sqrt{n(n+2)}\) → \(n = 2\)
Checking \(\text{Ni}^{2+}\): Ni (Z=28) = [Ar] 3d⁸ 4s². \(\text{Ni}^{2+}\) = [Ar] 3d⁸ → 2 unpaired electrons → \(\mu = \sqrt{2 \times 4} = \sqrt{8} \approx 2.83\) BM ✓

Correct Answer Logic:
ACI 318 formula: \(E_c = 57{,}000\sqrt{f'_c}\,\text{(psi)}\). \(E_c = 57{,}000\sqrt{3000} = 57{,}000 \times 54.77 \approx 3{,}122{,}000\,\text{psi} \approx 3.12 \times 10^6\,\text{psi}\), closest to option (a).

What is the ploidy level of the endosperm in angiosperms?
Correct Answer Logic:
In angiosperms, the endosperm is formed by triple fusion — the fusion of two polar nuclei (each haploid, n) with one male gamete (n) — resulting in a triploid (3n) nucleus. The endosperm develops into a nutritive tissue that nourishes the developing embryo. This is a unique feature of double fertilization in angiosperms.
