It is true that building techniques using steel played an important role in promoting the decentralization of the urban area.

Building techniques using steel played an important role in promoting the decentralization of the urban area. Steel is a versatile and durable material that allows for the construction of high-rise buildings, bridges, and other structures that can support large populations. Steel allows for the construction of taller buildings with larger floor areas, which leads to more efficient land use. This, in turn, encourages the spreading out of urban areas, as businesses and residents can be accommodated in smaller footprints. This has enabled cities to expand vertically, rather than horizontally, which helps to reduce urban sprawl and preserve natural areas.

Additionally, steel construction is often faster and more cost-effective than traditional building methods, making it an attractive option for developers looking to build in urban areas.  Steel's strength and durability enable the creation of longer bridges and tunnels, connecting urban areas with their surrounding regions and promoting further decentralization. Overall, the use of steel in building techniques has been instrumental in promoting decentralization and sustainable urban development.

The thing that  will happen to the Yield strength, the Tensile Strength, and the ductility. of a material if you increase the strain rate is option B: The Yield Strength and the Tensile Strength will increase, but the the ductility will decrease.

Boosting the strain rate or decreasing the temperature has the effect of raising the flow stress and decreasing ductility. The less uniform elongation before necking begins is what causes the poorer ductility; however, significant plastic flow may still be seen within the necked region.

Note that the primary distinction between yield strength and tensile strength is that the former refers to the lowest stress at which a material would permanently deform, whilst the latter refers to the highest tension at which a material will withstand before failing.

To determine the largest allowable length (l) of the column with a factor of safety of 3.2, we need to consider the buckling strength of the column.

The buckling strength of a column can be determined using the Euler's buckling formula:

P_critical = (π² * E * I) / (l_effective)²

Where:

P_critical is the critical buckling load

E is the modulus of flexibility (200 GPa)

I is the snapshot of dormancy of the segment cross-area

l_effective is the viable length of the segment

For a column with a uniform rectangular cross-section, the moment of inertia can be calculated as:

I = (b * d³) / 12

Given that b = 12 mm and d = 22 mm, we can calculate I.

Next, we need to determine the effective length of the column (l_effective). Since the column is braced at its midpoint, the effective length is half the total length:

l_effective = l / 2

Substituting the given values and solving for l in the Euler's buckling formula, we can find the largest allowable length of the column.

Once we obtain the critical buckling load (P_critical), we can then calculate the maximum allowable load (P_max) by dividing P_critical by the factor of safety (3.2):

P_max = P_critical / 3.2

By reworking the recipe, we can address for l:

l = sqrt((π² * E * I) / (P_max))

Substituting the calculated values, we can find the largest allowable length of the column (l). Finally, rounding the answer to the nearest whole number will give us the desired result.

Major internet applications such as the World Wide Web and file transfer rely on the Transmission Control Protocol (TCP) protocol.

The Transmission Control Protocol (TCP) is one of the core protocols of the Internet Protocol (IP) suite. TCP is a connection-oriented protocol that provides reliable and ordered delivery of data between applications running on different hosts. It is widely used by major internet applications such as the World Wide Web, email, file transfer, and streaming media.

TCP works by dividing data into packets and sending them between hosts using IP. The protocol ensures that all packets are received in the correct order and that any missing or corrupted packets are retransmitted. TCP also manages flow control to ensure that data is sent at an appropriate rate and that network resources are used efficiently.

The reliability and robustness of TCP have made it the protocol of choice for many internet applications, particularly those that require the transfer of large amounts of data. However, its connection-oriented nature and the overhead involved in managing connections make it less suitable for applications that require low latency or real-time communication, such as online gaming or VoIP (voice over internet protocol).

Answer:

21.6 kw

Explanation:

Given data:

m = 50 kg/s

Inlet pressure (p1) = 2 bar

outlet pressure(p2) = 6.2 bar

suction ( h1 ) = -2.2 m

delivery ( h2 ) = 8.5 m

d1 = 200 mm = 0.2 m

d2 = 100 mm = 0.1 m

Vs of water = 0.001 m^3/kg

next we have to determine the Q value

Q = V*A

Q = 0.001 * 50 = 0.05 m^3/s

next we have to calculate the various V's

V1 = Q/A1 = \(\frac{0.05*4}{\pi *0.2^2}\)  = 1.59 m/s

Answer:

(a)Tb = 330.12 K (b)Tc =304.73 K (c)19.81 K/m (d) h =60.65 W/m². K

Explanation:

Solution

Given that:

The mass flow rate of engine oil m = 1.81 x 10^-3 kg/s

Diameter of the tube, D = 1cm =0.01 m

Electrical heat rate, q =76 W/m

Wall Temperature, Ts = 370 K

Now,

From the properties table of engine oil we can deduce as follows:

thermal conductivity, k =0.139 W/m .K

Density, ρ = 854 kg/m³

Specific heat, cp = 2120 J/kg.K

(a) Thus

The wall heat flux is given as follows:

qs = q/πD

=76/π *0.01

= 2419.16 W/m²

Now

The oil mean temperature is given as follows:

Tb =Ts -11/24 (q.R/k) (R =D/2=0.01/2 = 0.005 m)

Tb =370 - 11/24 * (2419.16 * 0.005/0.139)

Tb = 330.12 K

(b) The center line temperature is given below:

Tc =Ts - 3/4 (qs.R/k)= 370 - 3/4 * ( 2419.16 * 0.005/0.139)

Tc =304.73 K

(c) The flow velocity is given as follows:

V = m/ρ (πR²)

Now,

The The axial gradient of the mean temperature is given below:

dTb/dx = 2 *qs/ρ *V*cp * R

=2 *qs/ρ*[m/ρ (πR²) *cp * R

=2 *qs/[m/(πR)*cp

dTb/dx = 2 * 2419.16/[1.81 x 10^-3/(π * 0.005)]* 2120

dTb/dx = 19.81 K/m

(d) The heat transfer coefficient is given below:

h =48/11 (k/D)

=48/11 (0.139/0.01)

h =60.65 W/m². K

The support reaction required to prevent the workshop from being lifted off the ground is 28,300 pounds.

Assuming the workshop area is rectangular, let's say its dimensions are 50 ft x 20 ft.

To calculate the wind pressure, we need to convert the wind velocity from mph to ft/s:

99.42 mph = 146.1 ft/s

Assuming the workshop is open on all sides, the wind pressure on each face of the building can be calculated as:

P = 0.00256 x V^2

where P is the pressure in pounds per square foot (psf), and V is the velocity in ft/s.

P = 0.00256 x (146.1)^2

P = 56.6 psf

The total wind force on the workshop is given by:

F = P x A

where A is the area of the workshop.

F = 56.6 psf x 1000 sq.ft

F = 56,600 lb

Assuming the support reaction is the force required to prevent the workshop from being lifted off the ground, we can calculate it as:

R = F / 2

since there are two supports, one on each end of the workshop.

R = 56,600 lb / 2

R = 28,300 lb

Answer:

the closest distance the center of gravity can be behind the front axle to have the vehicle achieve its maximum acceleration from rest on good, wet pavement is 47.8 in

Explanation:

Given that;

Weight of car W = 2600 lb

power = 80 hp = 44000 lb ft/s

Engine rpm = 3296

gear reduction ratio e = 10

drivetrain efficiency n = 95% = 0.95

wheel radius R = 16 in  = 1.3333 ft

Length of wheel base L = 95 in =

coefficient of road adhesion u = 0.60

height of center of gravity above pavement  h = 22 in

we know that;

Coefficient of rolling resistance frl = 0.01 for good wet pavement

distance of center of gravity behind the front axle lf = ?

Maximum tractive effort (Fmax) =  (uW / L) (lf - frl h) / (1 - uh / L)

First we calculate our Fmax to help us find lf

Power = Torque × 2π × Engine rpm / 60 )

44000 = Torque ( 2π×3296 / 60)

Torque = 127.5 lb ft  

so

Fmax = Torque × e × n / R

so we substitute in our values

Fmax = 127.5 × 10 × 0.95 / 1.333

Fmax = 908.66 lb

Now we input all our values into the initial formula

(Fmax) =  (uW / L) (lf - frl h) / (1 - uh / L)

908.66 =  [(0.6×2600/95) (lf - 0.01×22)] / [1 - 0.6×22) / 95]

908.66 = (16.42( lf - 0.22)) / 0.86

781.4476 = (16.42( lf - 0.22))

47.59 = lf - 0.22

lf = 47.59 + 0.22

lf = 47.8 in

Therefore the closest distance the center of gravity can be behind the front axle to have the vehicle achieve its maximum acceleration from rest on good, wet pavement is 47.8 in
