Civil Engineering QUESTION #2116

Question 1172

For a rectangular cross-section beam, the ratio of maximum shear stress to average shear stress is:

1.0
1.5✔️
2.0
1.33

Correct Answer Logic:

For a rectangular section of width $b$ and depth $d$: maximum shear stress occurs at the neutral axis $= \dfrac{3V}{2bd} = 1.5 \times \dfrac{V}{bd}$. Average shear stress $= \dfrac{V}{bd}$. Therefore ratio $= 1.5$. This is a fundamental result derived from the shear stress distribution formula $\tau = \dfrac{VQ}{Ib}$.

Question 1174

If the surface charge density of an infinite sheet increases by $25\%$, the electric field intensity:

Increases by $25\%$✔️
Increases by $50\%$

Question 1177

In respiratory acidosis caused by poor alveolar ventilation, what is the compensatory renal response to correct the blood pH?

Decrease the secretion of $\text{HCO}_3^-$ and thus increase the reabsorption of $\text{H}^+$
Increase the secretion of $\text{HCO}_3^-$ and thus decrease the reabsorption of $\text{H}^+$
Decrease the secretion of $\text{H}^+$ and thus increase the reabsorption of $\text{HCO}_3^-$
Increase the secretion of $\text{H}^+$ and thus increase the reabsorption of $\text{HCO}_3^-$✔️
