Boilers Mechanical Engineering QUESTION #2498

In Mohr's circle for plane stress, the principal stresses $\sigma_1$ and $\sigma_2$ occur at points where:

The circle has maximum radius
The circle intersects the $\sigma$-axis (shear stress $\tau = 0$)✔️
The shear stress is maximum
The normal stress equals the average stress

Correct Answer Logic:

Principal stresses are defined as the normal stresses acting on planes where shear stress is zero. On Mohr's circle, these correspond to the two points where the circle intersects the horizontal $\sigma$-axis (i.e., $\tau = 0$).

Question 4

A drink contains 20% mango juice and the rest is apple juice. What is the ratio of mango juice to apple juice?

$4 : 1$
$1 : 4$✔️
$1 : 20$
None of these

Correct Answer Logic:

If the drink contains 20% mango juice, then it contains 80% apple juice (100% - 20% = 80%). The ratio of mango to apple juice is $20 : 80 = 1 : 4$. This means for every 1 part mango juice, there are 4 parts apple juice.

Geology QUESTION #10675

Question 7

The apparent dip of a bed measured in any vertical section other than the true dip direction is always:

Greater than the true dip
Equal to the true dip
Less than the true dip✔️
Depends on the exact dip angle

Correct Answer Logic:

The apparent dip is always less than or equal to the true dip. The relationship is: $\tan(\alpha) = \tan(\delta) \cdot \cos(\beta)$, where $\alpha$ = apparent dip, $\delta$ = true dip, and $\beta$ = angle between the measured section and the true dip direction. When $\beta = 0°$ (section perpendicular to strike), $\cos\beta = 1$ and apparent dip equals true dip. For any other section orientation, $\cos\beta < 1$, so apparent dip $< $ true dip.

Question 20

The product of inertia $I_{xy}=\int xy\,dA$ is ZERO when:

The area has no curved boundaries
The area is symmetric about EITHER the x- OR y-axis✔️
The second moments $I_x$ and $I_y$ are equal
The area is a polygon

Correct Answer Logic:

The product of inertia is zero whenever the area has an axis of symmetry that coincides with either the x- or y-axis. The symmetric pairs of elemental areas contribute equal and opposite $xy\,dA$ terms that cancel.
