Boilers Mechanical Engineering QUESTION #2496

The flexure (bending stress) formula for a beam subjected to bending moment $M$ gives stress $\sigma$ at distance $y$ from the neutral axis as:

$\sigma = \frac{My}{I}$✔️
$\sigma = \frac{MI}{y}$
$\sigma = \frac{M}{yI}$
$\sigma = \frac{y}{MI}$

Correct Answer Logic:

Derived from pure bending theory (Euler-Bernoulli beam), $\sigma = -My/I$. Maximum bending stress occurs at $y = c$ (outermost fiber): $\sigma_{max} = Mc/I = M/Z$, where $Z = I/c$ is the section modulus.

Electronics Engineering QUESTION #11715

Question 3632

A Li-ion cell is charged using CC-CV (constant current / constant voltage) method. At what voltage does the charger switch from CC to CV phase?

3.0 V (end of discharge)
3.7 V (nominal voltage)
4.2 V (full charge voltage)✔️
4.5 V (overcharge threshold)

Correct Answer Logic:

Li-ion cells are charged in two phases: Constant Current (CC) from depleted state up to 4.2 V, then Constant Voltage (CV) at 4.2 V until current tapers to ~C/10 or C/20 (typically 50–100 mA), indicating full charge. Exceeding 4.2 V causes electrolyte decomposition, lithium plating, and severe safety hazards including thermal runaway.
