In the context of buildings, structures designed to mitigate the effects of seismic activity or strong winds are commonly referred to as seismic or base isolators.

These isolators act as shock absorbers to reduce the transmission of vibrations and energy from the ground to the building. Seismic or base isolators typically consist of various materials or devices that can absorb and dissipate energy. Some commonly used types of isolators include:

1. Rubber or Neoprene Bearings: These are made of rubber or neoprene pads that provide flexibility and damping to absorb and dissipate energy during seismic events.

2. Sliding Bearings: Sliding bearings allow the building to slide horizontally on a low-friction surface, such as PTFE (polytetrafluoroethylene). This sliding motion helps to reduce the transfer of seismic forces to the building.

3. Fluid Dampers: Fluid dampers utilize the properties of viscous fluid to absorb and dissipate energy. They consist of cylinders filled with a viscous fluid that flows through small orifices, generating resistance against the motion caused by seismic forces.

4. Steel Springs: Steel springs can be used as shock absorbers to reduce the impact of seismic or wind loads. They provide flexibility and absorb energy by deforming under the applied forces.

These seismic or base isolators are strategically placed at the base or foundation of the building to reduce the transfer of vibrations and energy. By incorporating these shock-absorbing mechanisms, buildings can better withstand seismic events and minimize structural damage.

True, aₙ₊₁ = 2aₙ₋₁ is a one-step recurrence relation because it only depends on the previous term, aₙ₋₁.

False, the recurrence relation aₙ = 4aₙ₋₁ + 5aₙ₋₂ for all n ≥ 2 does not have exactly one solution for each ordered pair (a₀, a₁) of initial conditions. This is because the general solution to this recurrence relation involves a linear combination of two exponential terms, which depend on the roots of the characteristic equation.

Therefore, the solution will depend on the initial conditions and can take on different values for different initial conditions.

However, it is true that the function f: ℝ × ℝ → S defined as f(a,b) = the sequence {aₙ} ∈ S with a₀=a, a₁=b is well-defined, meaning that for each pair of real numbers (a,b), there exists a unique sequence that satisfies the recurrence relation with those initial conditions. However, this function is not a bijection, since multiple pairs of initial conditions can lead to the same sequence.

0.268 kg of water must be added to increase the pressure to 70 Mpa (gage).

To find the amount of water needed to increase the pressure to 70Mpa, we need to use the formula:

Change in volume = (Initial volume) x (Change in pressure)

                                            Young's modulus

The initial volume of the container is 8 liters, since the container holds 8kg of water at standard pressure and the density of water is 1000 kg/m³.

So, change in volume = 8 x 10⁻³ m³

We know that the container expands by 1% when the pressure inside it is increased by 70 MPa, and we want to find the amount of water needed to increase the pressure to 70 MPa.

So, Change in pressure = 70 MPa

Young's modulus (K) = 2.05 GPa

Therefore, Change in volume = (8 x 10⁻³) x (70 / 2.05 x 10^9) = 2.68 x 10⁻⁵ m³

To find the amount of water needed to increase the pressure to 70 MPa, we need to multiply the change in volume by the density of water.

So, amount of water needed = (2.68 x 10⁻⁵) x (1000) = 0.268 kg

Therefore, 0.268 kg of water must be added to increase the pressure to 70 Mpa (gage).

The mass of air in the tank is approximately 0.838 kg.

To find the mass of air in the tank, we first need to determine the density of the air at the given temperature and pressure.

The ideal gas law can be used for this calculation, which is:

PV = nRT

where:

P is the pressure (500 kPa or 500,000 Pa)

V is the volume (10 m³)

n is the number of moles of the gas

R is the specific gas constant for air (287 J/(kg·K))

T is the temperature (600 K)

First, we'll find the number of moles (n):

n = PV/RT

n = (500,000 Pa * 10 m³) / (287 J/(kg·K) * 600 K)

n = 5000000 / (287 * 600)

n ≈ 28.918 moles

Now, we'll convert moles to mass using the molar mass of air. The molar mass of dry air is approximately 28.97 g/mol or 0.02897 kg/mol:

mass (m) = n * molar mass

m = 28.918 moles * 0.02897 kg/mol

m ≈ 0.838 kg

So, the mass of air in the tank is approximately 0.838 kg.

C. Signal-to-quantization-noise ratio

Explanation:

An automobile travels along a straight road at 15.65 m/s through a 11.18 m/s speed zone. A police car observed the automobile. At the instant that the two vehicles are abreast of each other, the police car starts to pursue the automobile at a constant acceleration of 1.96 m/s2 . The motorist noticed the police car in his rear view mirror 12 s after the police car started the pursuit and applied his brakes and decelerates at 3.05 m/s2

Find the total time required for the police car  to over take the automobile.

Answer:

15.02 sec

Explanation:

The total time required for the police car to overtake the automobile is related to the distance covered by both  cars which is equal from instant point of abreast.

So; we can say :

\(D_{pursuit} =D_{police}\)

By using the second equation of motion to find the distance S;

\(S= ut + \dfrac{1}{2}at^2\)

\(D_{pursuit} = (15.65 *12 )+(15.65 (t)+ (\dfrac{1}{2}*(-3.05)t^2)\)

\(D_{pursuit} = (187.8)+(15.65 \ t)-0.5*(3.05)t^2)\)

\(D_{pursuit} = (187.8+15.65 \ t-1.525 t^2)\)

\(D_{police} = ut _P + \dfrac{1}{2}at_p^2\)

where ;

u  = 0

\(D_{police} = \dfrac{1}{2}at_p^2\)

\(D_{police} = \dfrac{1}{2}*(1.96)*(t+12)^2\)

\(D_{police} = 0.98*(t+12)^2\)

\(D_{police} = 0.98*(t^2 + 144 + 24t)\)

\(D_{police} = 0.98t^2 + 141.12 + 23.52t\)

Recall that:

\(D_{pursuit} =D_{police}\)

\((187.8+15.65 \ t-1.525 t^2)= 0.98t^2 + 141.12 + 23.52t\)

\((187.8 - 141.12) + (15.65 \ t - 23.52t) -( 1.525 t^2 - 0.98t^2) = 0\)

= 46.68 - 7.85 t -2.505 t² = 0

Solving by using quadratic equation;

t = -6.16 OR  t = 3.02

Since we can only take consideration of the value with a  positive integer only; then t = 3.02 secs

From the question; The motorist noticed the police car in his rear view mirror 12 s after the police car started the pursuit;

Therefore ; the total time  required for the police car  to over take the automobile = 12 s + 3.02 s

Total time  required for the police car  to over take the automobile = 15.02 sec

Answer:

  (a)  -55.6%, -31.25 V

  (b) -11.1%, -6.25 V

  (c) -0.93%, -0.52 V

Explanation:

The open-circuit voltage is (75V)(750/(250+750)) = 56.25 V.

The circuit to which the meter is connected has a Thevenin equivalent impedance of 1/(1/250 +1/750) = 187.5 kΩ. So, the relative error for a given meter impedance of R (in kΩ) is ...

  (R/(R +187.5) -1) × 100% = -187.5/(R +187.5) × 100%

(a) For a meter impedance of (1 kΩ/V)×150V = 150 kΩ, the error is ...

  -187.5/(150 +187.5) × 100% ≈ -55.6%

The voltage error is (56.25 V)(-55.6%) = -31.25 V.

__

(b) For a meter impedance of (20 kΩ/V)×75V = 1500 kΩ, the error is ...

  -187.5/(1500+187.5) × 100% ≈ -11.1%

The voltage error is (56.25 V)(-5.88%) = -6.25 V.

__

(c) For a meter impedance of 20,000 kΩ, the error is ...

  -187.5/(20000+187.5) × 100% ≈ -0.93%

The voltage error is (56.25 V)(-0.93%) = -0.52 V.

Answer:

The overall transfer function for the two systems in series is 2/ s²(2s + 1)(3s + 1).

It should be noted that to develop the transfer function for the two systems in series, we need to first express them in terms of transfer functions:

For the first system:

2dy/dt + y = 1

2sY(s) + Y(s) = 1/s

Y(s)(2s + 1) = 1/s

Y(s) = 1/s(2s + 1)

For the second system:

3dy/dt + y = 2

3sY(s) + Y(s) = 2/s

Y(s)(3s + 1) = 2/s

Y(s) = 2/s(3s + 1)

The overall transfer function for the two systems in series is obtained by multiplying their individual transfer functions, since the output of the first system is the input to the second system.

Hence, the overall transfer function is given by:

G(s) = Y(s)/X(s) = (1/s(2s + 1)) * (2/s(3s + 1))

G(s) = 2/ s²(2s + 1)(3s + 1)

If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,

P=2×pi×N×T/60 or T=60×p/2×pi×N

Where P=power transmitted by the shaft=50×10³W

N=rotation speed of the shaft in rpm=730rpm

Pi=3.142

T is the twisting moment

By substituting the values for pi, N and P, we get

T=654Nm or 654×10³Nmm

Also, T=pi×rho×d³/16 or rho=16×T/pi×d³

Where rho=maximum shear stress

T = twisting moment=654×10³Nmm

d= diameter of shaft= 40mm

By substituting T, pi and d

Rho=52Mpa

b. For a hollow shaft, the value for rho is unknown

T=pi×rho(do⁴-di⁴/do)/16

Rho=T×16×do/pi×(do⁴-di⁴)

Where

T= twisting moment=654×10³Nmm gotten above

do=outside shaft diawter=40mm

di= inside shaft diameter =30mm

Pi=3.142

Substituting values for pi, do, di and T.

Dynamic price optimization for airlines involves using data and algorithms to adjust the prices of airline tickets in real-time based on demand and other factors.

The example of a project that uses dynamic price optimization is:

Imagine you are the manager of a small airline that operates flights between two cities. You want to maximize your revenue by selling as many tickets as possible at the highest price possible. To do this, you decide to implement a dynamic pricing system that adjusts the prices of your tickets based on demand.

To start, you collect data on past ticket sales and other factors that may affect demand, such as the time of year, the day of the week, and the weather. You also gather data on the prices of tickets offered by your competitors.

Later on, you use machine learning algorithms to analyze this data and identify patterns that can help predict demand for your flights. Based on this analysis, you create a model that can adjust the prices of your tickets in real-time based on the predicted demand.

Therefore, to implement the dynamic pricing system, you create a software program that integrates with your ticketing system and automatically adjusts the prices of your tickets based on the predictions made by your model. You also set up a system to monitor the performance of your dynamic pricing system and make adjustments as needed.

The resistance of the flow of charges in an electric circuit (electrical resistance) is analogous to the frictional effect between water flow through a pipe and the pipe's surface

Explanation:

In comparison to its similarity to the diameter of the pipe affects the flow of water and acts a a factor affecting resistance so are there factors affecting electrical resistance.

in an electrical circuit:

the total length of the wire is to the length of a pipe of water

the cross-sectional area of the wire is to the diameter of a pipe of water.

Thus, the cross sectional are affects the amount of electrical resistance. Wider wires have wider cross-sectional area and vice versa. Also, water will flow (i.e. current) through a wider pipe (i.e. large diameter) at a faster rate than a narrow pipe (i.e. small diameter). This is due to the lower amount of resistance offered by the wider pipe.

in the same manner, the wider the wire, the lesser the electrical resistance to the flow of elsctric charge and vice versa for thiner wires.

A wide moving belt passes through a container of a viscous liquid pressure changes due to the change in elevation of the fluid as it rises are already captured by the gravity term in the Navier-Stokes equations

Because there is little air drag on the film. The Shearing stress at the free surface (or any interior parallel surface) is designed as Zxy, where

Zxy = μ dv/dx

c) If Zxy = 0 at x = h

Then 0 = γh/μ + C1

C1 = - γh / μ

Now integrating equation gives the velocity distribution in the film as

v = γ x² / 2μ - γh/μ + C2

At the belt (x=0) the fluid velocity must match the belt velocity Ve so that

V0 = 0-0+C2

C2 = V0

and the velocity  distribution is therefore

v = γ x² / 2μ - γh/μ + V0

with the velocity distribution knowm we can determine the flowrate per unit width q from the relationship

q = ∫ Vdx = ∫ γ x² / 2μ - γh/μ + V0 dx

and thus q = V0 h - γh³/3μ

The average velocity V (where, Q = Vh ) is
