Answer:

This can be achieved through the use of a built-in fiber-optic network of cables that deliver light and heat energy to the point of breakage.

Explanation:

Self-healing polymers are materials designed to aid the internal healing of materials like plastics, and metals. Shape-memory materials used in the making of plastic frames for glasses and sunglasses allow these materials to snap back into shape when they crack.

This is possible because heat is needed to help a deformed material regain its shape. Built-in fiber-optic network of cables serve the purpose of delivering heat to the deformed or cracked area, thus helping them to regain their shape.

To determine the allowable load P, we need to calculate the shear and normal stresses at each connection. The shear stress at each connection can be calculated using the equation τ = P/A, where P is the load and A is the area of the pin.

The normal stress at each connection can be calculated using the equation σ = P/A, where P is the load and A is the cross-sectional area of the link. Once the shear and normal stresses have been calculated, we can compare them to the ultimate shear and normal stresses to determine the allowable load. The allowable load will be the load that produces a shear and normal stress that is equal to or less than the ultimate shear and normal stresses, multiplied by the factor of safety.

To calculate the allowable load, we need to first calculate the shear and normal stresses at each connection. The shear stress at each connection can be calculated using the equation τ = P/A, where P is the load and A is the area of the pin. The area of the pin can be calculated using the equation A = πr2, where r is the radius of the pin. The normal stress at each connection can be calculated using the equation σ = P/A, where P is the load and A is the cross-sectional area of the link. The cross-sectional area of the link can be calculated using the equation A = bh, where b is the width of the link and h is the height of the link. Once the shear and normal stresses have been calculated, we can compare them to the ultimate shear and normal stresses to determine the allowable load. The allowable load will be the load that produces a shear and normal stress that is equal to or less than the ultimate shear and normal stresses, multiplied by the factor of safety.

The local isentropic stagnation conditions in front of the shock and estimate the stagnation pressure sensed by the pitot tube.

a) To evaluate the local isentropic stagnation conditions in front of the shock, we can use the isentropic relations for a perfect gas. The isentropic relations relate the properties of a gas across a shock wave. Given the altitude of 12 km and the provided pressure and temperature of the surrounding air (19.4 kPa and -56.45 °C), we can calculate the local isentropic stagnation conditions.

First, we need to convert the temperature from Celsius to Kelvin:

T = -56.45 °C + 273.15 = 216.7 K

Using the ideal gas equation, we can calculate the density of the surrounding air:

ρ = P / (R * T)

Where P is the pressure, R is the specific gas constant, and T is the temperature.

For air, the specific gas constant R is approximately 287 J/(kg·K).

ρ = 19.4 kPa / (287 J/(kg·K) * 216.7 K)

After performing the calculation, we obtain the density of the surrounding air.

Now, using the isentropic relations, we can determine the isentropic stagnation conditions ahead of the shock. These conditions can be obtained by relating the Mach number (M) and the local conditions (P, ρ, T) to the isentropic stagnation conditions (P0, ρ0, T0).

The specific heat ratio (gamma) for air is approximately 1.4.

M0 = M * √(γ * R * T0 / (2 * γ * R * T))

Where M0 is the isentropic Mach number and T0 is the isentropic stagnation temperature.

Using this equation, we can solve for T0 and calculate the isentropic stagnation temperature.

Similarly, we can calculate the isentropic stagnation pressure (P0) using the relation:

P0 = P * (1 + ((γ - 1) / 2) * M^2)^(γ / (γ - 1))

By substituting the known values, including the calculated density (ρ), pressure (P), and temperature (T), we can obtain the isentropic stagnation pressure sensed by the pitot tube.

b) To estimate the stagnation pressure sensed by the pitot tube, we can consider that the pitot tube measures the stagnation pressure, which is the total pressure (P0) ahead of the shock. Therefore, the calculated isentropic stagnation pressure (P0) from part a) represents the stagnation pressure sensed by the pitot tube.

By following these calculations, we can evaluate the local isentropic stagnation conditions in front of the shock and estimate the stagnation pressure sensed by the pitot tube.

Answer:

a). 139498.24 kg

b). 281.85 ohm

c). 10.2 ohm

Explanation:

Given :

Diameter, d = 22 m

Linear strain, \($\epsilon$\) = 3%

                        = 0.03

Young's modulus, E = 30 GPa

Gauge factor, k = 6.9

Gauge resistance, R = 340 Ω

a). Maximum truck weight

σ = Eε

σ = \($0.03 \times 30 \times 10^9$\)

\($\frac{P}{A} =0.03 \times 30 \times 10^9$\)

\($P = 0.03 \times 30 \times 10^9\times \frac{\pi}{4}\times (0.022)^2$\)

 = 342119.44 N

For the four sensors,

Maximum weight = 4 x P

                            =  4 x 342119.44

                            = 1368477.76 N

Therefore, weight in kg is \($m=\frac{W}{g}=\frac{1368477.76}{9.81}$\)

                     m = 139498.24 kg

b). Change in resistance

\(k=\frac{\Delta R/R}{\Delta L/L}\)

\($\Delta R = k. \epsilon R$\)    , since \($\epsilon= \Delta L/ L$\)

\($\Delta R = 6.9 \times 0.03 \times 340$\)

\($\Delta R = 70.38 $\) Ω

For 4 resistance of the sensors,

\($\Delta R = 70.38 \times 4 = 281.52$\) Ω

c). \($k=\frac{\Delta R/R}{\epsilon}$\)

If linear strain,

\($\frac{\Delta R}{R} \approx \frac{\Delta L}{L}$\)  , where k = 1

\($\Delta R = \frac{\Delta L}{L} \times R$\)

\($\Delta R = 0.03 \times 340$\)

\($\Delta R = 10.2 $\) Ω

Answer:

Answer is 3.2 Ω (Ohms)

Explanation:

From Ohms Law I = V/R

R = V(I)

R = 8(0.4)

R = 3.2

The resistance of a lamp if the current through it is 0.4 A and the voltage across it is 8 V is 3.2 ohm.

According to Ohm's law, when all other physical parameters, including temperature, are held constant, the voltage across a conductor is directly proportional to the current flowing through it.

According to Ohm's Law, the electrical current I flowing through a particular conductor is precisely proportional to the potential difference (voltage) V across its ends (assuming that the conductor's physical properties, such as its temperature and pressure, stay constant). where R is a proportionality constant.

Given:

Current, I= 0.4 A

Voltage, V= 8 V

Using Ohm's Law

V= IR

I = V/R

R = V(I)

R = 8(0.4)

R = 3.2 ohm

Hence, the resistance of a lamp if the current through it is 0.4 A and the voltage across it is 8 V is 3.2 ohm.

The shrinkage that occurs in fresh concrete before it hardens is called plastic shrinkage. This type of shrinkage happens due to a rapid loss of moisture from the surface of the concrete. During the curing process, the surface dries out faster than the rest of the concrete, causing it to shrink and crack. Plastic shrinkage is more likely to occur in hot and dry weather conditions or when the concrete is exposed to high winds. It can be prevented by taking measures such as using curing compounds, using windbreaks, or adding fibers to the concrete mix.

Failure to address plastic shrinkage can result in weakened concrete structures and costly repairs. It is essential to identify the type of shrinkage and take system to mitigate it to ensure a durable and robust concrete structure.
