Physics, Surveying, Transportation, and Engineering Review

Comprehensive practice flashcards covering basic Physics (Kinematics/Kinetics), Surveying (Horizontal/Vertical Curves, Errors), Transportation (Pavements, Traffics), and Structural Design (RCD, Steel, Soil Mechanics).

In Physics: Kinematics, what is the value of acceleration due to gravity ($g$) in SI and English units?

$$g = 9.81\,m/s^2 = 32.2\,ft/s^2$$

Under Physics: Kinetics, what are Newton's three laws of motion as defined in the notes?

1st LAW: An object stays at rest unless force is added; 2ND LAW: $F = ma$; 3RD LAW: One object exerts an equal amount of force to the second object.

What are the values of the coefficient of restitution ($e$) for elastic, inelastic, and perfectly inelastic collisions?

Elastic collision: $e = 1$; Inelestic collision: $e = 0$; Perfectly Inelastic collision: $0 < e < 1$.

In Physics: Waves, what is the velocity of sound in air ($V_{sound}$) used in calculations?

$$343\,m/s$$

In Surveying: Theory of Errors, what is the formula for Residual ($v$)?

$$v = X - MPV$$

In Surveying: Tape Corrections, how is the sign of the pull correction ($\Delta p$) determined?

If $P_2 > P_1$, then $\Delta p = +C$; if $P_2 < P_1$, then $\Delta p = -C$.

What is the difference between Azimuths and Bearings according to the lecture notes?

Azimuths are horizontal angles observed from any reference meridian, while Bearings are acute angles between a reference meridian and the line.

In Surveying: Horizontal Curves, what are the default bases for the Degree of Curvature?

Arc Basis is the default; Chord Basis is the alternative.

In Transportation Engineering, what value is assigned to time ($t$) for Safe Stopping Distance (SSD)?

$$t = 2.5\,sec$$

What does the abbreviation PIEV stand for in Transportation Engineering?

Perception, Intellectual, Emotion, Volition.

In Construction Engineering, define the relationship for Void Ratio ($e$) and Porosity ($n$).

Void Ratio ($e$) is $\frac{V_v}{V_s}$; Porosity ($n$) is $\frac{V_v}{V_t}$, where $0 < n < 1$.

In Construction Engineering: Production, what is the volume ($V$) formula for a conical spoil bank?

$$V = \frac{\pi D^2 H}{12}$$

What are the yield ($F_y$) and ultimate ($F_u$) stresses (MPa) for A36 steel?

$F_y = 248\,MPa$ and $F_u = 400\,MPa$.

In RCD Provisions, what are the concrete cover ($cc$) requirements for Beams/Columns, Slabs, and Footings?

Beam/Column: $40\,mm$; Slab: $20\,mm$; Footing: $75\,mm$.

In RCD Shear, what is the simplified formula for the shear strength of concrete ($V_c$)?

$$V_c = 0.17 \lambda \sqrt{f'_c} b_w d$$

What is the formula for the Slenderness Ratio ($SR$) in Steel - Compression Members?

$$SR = \frac{KL}{r}$$

In Soil - Consistency, what is the Plastic Limit ($PL$) test requirement for thread diameter?

$3.2\,mm$ in diameter.

In Geotechnical Engineering, how is Effective Normal Stress ($\sigma_e$) derived?

$\sigma_e = \sigma_T - P_w$, where $\sigma_T$ is Total Normal Stress and $P_w$ is Pore Water Pressure.

In Geotechnical Engineering: Shear, what is the Mohr-Coulomb Failure Criterion formula?

$$\tau = c + \sigma \tan(\phi)$$

In Geotechnical Engineering: Deep Foundation, how is the Total Capacity ($Q_{ULT}$) of a pile calculated?

$Q_{ULT} = Q_B + Q_F$, where $Q_B$ is Tip Resistance and $Q_F$ is Skin Frictional Resistance.
