Question 3

A wide-flange section is used as a beam-column. If the axial load ratio $P_u / (\phi P_n)$ is greater than 0.2, which interaction equation form is required by AISC?

$\frac{P_u}{\phi P_n} + \frac{M_u}{\phi M_n} \le 1.0$
$\frac{P_u}{2\phi P_n} + \frac{M_u}{\phi M_n} \le 1.0$
$\frac{P_u}{\phi P_n} + \frac{8}{9}(\frac{M_{ux}}{\phi_b M_{nx}} + \frac{M_{uy}}{\phi_b M_{ny}}) \le 1.0$✔️
$\frac{P_u}{\phi P_n} + \frac{1}{2}(\frac{M_u}{\phi M_n}) \le 1.0$

Correct Answer Logic:

For $P_u / \phi P_n \ge 0.2$, the AISC interaction formula weights the axial component fully and reduces the moment component slightly (multiplied by 8/9). For ratios < 0.2, the axial component is halved.

Question 11

A firm's goods are sold at a margin of 25% on sales. Purchases = Rs. 155,000; Opening Stock = Rs. 10,000; Closing Stock = Rs. 15,000. What are total Sales?

Rs. 200,000✔️
Rs. 150,000
Rs. 187,500
Rs. 175,000

Correct Answer Logic:

COGS = 10,000 + 155,000 – 15,000 = Rs. 150,000. Margin = 25%, so COGS = 75% of Sales. Sales = 150,000 × 100/75 = Rs. 200,000. The margin formula: Sales = COGS/(1 – Margin%) = 150,000/0.75.

Mathematics QUESTION #6015

Question 15

If the matrix $P = \begin{pmatrix}1 & \alpha & 3\\1 & 3 & 3\\2 & 4 & 4\end{pmatrix}$ is the adjoint of a $3\times3$ matrix $A$ with $|A|=4$, find $\alpha$.

4
11✔️
5

Correct Answer Logic:

We use the property: $|adj(A)| = |A|^{n-1}$ for an $n\times n$ matrix. Here $n=3$, so $|P| = |A|^2 = 16$.

Compute $|P|$ by expanding along row 1 (with unknown $\alpha$):

$|P| = 1(3\cdot4-3\cdot4) - \alpha(1\cdot4-3\cdot2) + 3(1\cdot4-3\cdot2)$

$= 1(0) - \alpha(4-6) + 3(4-6) = 2\alpha - 6$

Setting $2\alpha - 6 = 16 \Rightarrow 2\alpha = 22 \Rightarrow \alpha = \mathbf{11}$
