Mechanical Engineering QUESTION #2487

The acceleration of node B of a driver link with angular velocity $\omega$ and angular acceleration $\alpha=\ddot{\phi}$ has components:

$a_{Bx} = -L_{AB}\omega^2\cos\phi + L_{AB}\alpha\sin\phi$; $a_{By} = -L_{AB}\omega^2\sin\phi - L_{AB}\alpha\cos\phi$
$a_{Bx} = -L_{AB}\omega^2\cos\phi - L_{AB}\alpha\sin\phi$; $a_{By} = -L_{AB}\omega^2\sin\phi + L_{AB}\alpha\cos\phi$✔️
$a_{Bx} = L_{AB}\alpha\cos\phi$; $a_{By} = L_{AB}\alpha\sin\phi$
$a_{Bx} = -L_{AB}\omega^2\cos\phi$; $a_{By} = -L_{AB}\omega^2\sin\phi$

Correct Answer Logic:

Differentiating velocity: $a_{Bx}=-L_{AB}\alpha\sin\phi-L_{AB}\omega^2\cos\phi$ and $a_{By}=L_{AB}\alpha\cos\phi-L_{AB}\omega^2\sin\phi$.

Agronomy QUESTION #2038

Question 4612

Hermetic storage technology for grain preservation works on the principle of:

Maintaining grain at constant low temperature using refrigeration
Creating a modified atmosphere inside an airtight container where respiration of grain, insects, and fungi consumes O₂ and raises CO₂, killing pests without chemicals✔️
Treating grain with phosphine gas before sealing
Using UV-treated bags to prevent insect entry

Correct Answer Logic:

Hermetic (airtight) storage exploits the biological process: grain, insects, and microbes respire, consuming O₂ and producing CO₂ within the sealed container. The resulting hypoxic/hypercapnic atmosphere kills insects and suppresses fungal growth without chemical inputs — ideal for smallholder grain storage.

In a Randomized Complete Block (RCB) design with $b = 9$ blocks and $t = 4$ treatments, the error degrees of freedom is:

35
32
24✔️
27

Correct Answer Logic:

Error df in RCBD $= (b-1)(t-1) = (9-1)(4-1) = 8 \times 3 = 24$. Equivalently, total df $= bt - 1 = 35$, blocks df $= b - 1 = 8$, treatments df $= t - 1 = 3$, so error df $= 35 - 8 - 3 = 24$.
