We must break down the forces acting on the eyeball into their component parts to calculate the required values ​​of T and (theta), and we must use the concept of equilibrium, which states that the net force acting on an object and net torque are both zero.

Let us examine in more detail the forces affecting the eyeball:

The equations for balancing in the x and y directions will now be presented as:

No pressure is acting in the x-direction, so the tension force is zero in that direction: T * cos(θ) = 0

T * sin(θ) + \(\rm F_1 + F_2 - F_3\)= 1200N (net pull force of 1200N in y-direction due to tension force in y-direction, f1, f2 and f3)

Let us now find the value of T and θ:

From the x-direction equation, we get:

T * cos(θ) = 0

T = 0

From the y-direction equation, we get:

0 + 500N + 800N - 600N = 1200N

T * sin(θ) = 1200N

T = 1200N / sin(θ)

Since T cannot be both 0 and 1200N, it implies that sin(θ) must be equal to 1:

sin(θ) = 1

To find θ, we take the inverse sine (or arcsine) of 1:

θ = arcsin(1)

The arcsine of 1 is 90 degrees or π/2 radians.

Therefore, the values are T = 1200N / sin(θ) = 1200N / 1 = 1200N and θ = 90 degrees or π/2 radians.

The total wall area that needs to be insulated is -29 ft².

The negative value indicates that the area of the window and door openings exceeds the total wall area, which seems unlikely. It's important to note that the given dimensions or calculations might contain errors or inconsistencies. Double-checking the measurements or obtaining accurate dimensions will be necessary to provide a valid answer.

To determine the total wall area that needs to be insulated, we first need to calculate the area of the window and door openings and subtract it from the total wall area.

The dimensions of the window and door openings are not provided, but we know that their combined area is approximately 125 ft². Let's assume that the window and door openings are rectangular in shape.

Let's calculate the area of the window and door openings:

Area = Length × Width

Given that the combined area is 125 ft², we can assume:

Area of window and door openings = 125 ft²

Now, let's calculate the total wall area that needs to be insulated:

Total wall area = Wall area - Area of window and door openings

To calculate the wall area, we need to find the perimeter of the home and multiply it by the height of the walls. Assuming the home is rectangular:

Perimeter = 2 × (Length + Width)

Total wall area = Perimeter × Height

Let's substitute the given dimensions into the equations:

Perimeter = 2 × (42" + 30") = 144 inches

Total wall area = (144 inches × 8 feet) / 12 = 96 ft²

Finally, we can calculate the total wall area that needs to be insulated:

Total wall area = 96 ft² - 125 ft² = -29 ft²

The negative value indicates that the area of the window and door openings exceeds the total wall area, which seems unlikely. It's important to note that the given dimensions or calculations might contain errors or inconsistencies. Double-checking the measurements or obtaining accurate dimensions will be necessary to provide a valid answer.

The impurity concentration of a metal can have a significant impact on its mechanical properties. In this case, we are interested in the effect of increasing impurity concentration on the tensile and yield strengths of the metal. In this answer, we will provide an explanation of what happens to the strengths as impurity concentration increases and conclude with a summary of our findings.

As the impurity concentration of a metal is increased, the tensile and yield strengths should decrease. This is because the impurities disrupt the crystal structure of the metal, making it harder for dislocations to move through the material. Dislocations are defects in the crystal structure that allow plastic deformation to occur. When a metal is subjected to stress, dislocations move and allow the metal to deform. However, when there are impurities present, they can interfere with the movement of dislocations, making it more difficult for the metal to deform. This, in turn, reduces the strength of the metal.

It's important to note that this effect is most pronounced for substitutional impurities, which replace some of the metal atoms in the crystal lattice. Interstitial impurities, which occupy spaces between the metal atoms, have a smaller effect on the mechanical properties of the metal.

In summary, increasing impurity concentration in a metal should lead to a decrease in its tensile and yield strengths. This is because impurities disrupt the crystal structure of the metal and make it harder for dislocations to move through the material, which reduces its ability to deform and, therefore, reduces its strength. This effect is most pronounced for substitutional impurities.

The ratio of shear strength of the clay in vertical direction to that in horizontal direction is 1.41.

The force that can cause an object to rotate along an axis is measured as torque. Similar to how force accelerates an item in linear kinematics, torque accelerates an object in an angular direction.

The apparent shear stress of the soil can be calculated using the following formula:

τ = T/(2πLW)

Where τ is the apparent shear stress, T is the torque at failure, L is the length of the vane, and W is the width of the vane.

For the first test with the vane of length 150mm and diameter 60mm:

τ1 = 46/(2π × 0.15 × 0.06) = 666.67 kPa

For the second test with the vane of length 200mm and diameter 90mm:

τ2 = 138/(2π × 0.2 × 0.09) = 402.23 kPa

To calculate the ratio of shear strength of the clay in vertical direction to that in horizontal direction, we can use the formula:

tan φ = (τv - σ)/τh

Where φ is the angle of internal friction, τv is the shear strength in the vertical direction, τh is the shear strength in the horizontal direction, and σ is the normal stress.

Assuming that the normal stress is the same in both directions, we can rearrange the formula to get:

τv/τh = tan φ + 1

To find the angle of internal friction, we can use the average of the two apparent shear stresses:

φ = (1/2) × arctan((τ1/2 + τ2/2)/σ) = (1/2) × arctan((534.45 + 333.33)/σ)

Assuming a normal stress of 100 kPa, we get:

φ = (1/2) × arctan(867.78/100) = 21.16°

Substituting this value into the formula for the ratio of shear strength, we get:

τv/τh = tan(21.16°) + 1 = 1.41

Therefore, 1.41 the ratio of shear strength of the clay in vertical direction to that in horizontal direction.

Answer:

35 g/mol

Explanation:

Convert to SI units.

465 R × 5/9 = 258.3 K

Assuming the pressure is absolute pressure:

135 psi × (101.3 kPa / 14.7 psi) = 930.3 kPa

Ideal gas law:

PV = nRT

(930.3 kPa) (15 L) = n (8.314 kPa L / mol / K) (258.3 K)

n = 6.50 mol

The molar mass is therefore:

230 g / 6.50 mol = 35.4 g/mol

Rounded to two significant figures, the molar mass is 35 g/mol.

Answer:

A.) Time = 17.13 seconds

B.) Distance = 31.9 m

C.) V = 11.18 m/s

D.) V = 7.1 m/s

Explanation:

The initial velocity U of the automobile is 15.65 m/s.

 At the instant that the two vehicles are abreast of each other, the police car starts to pursue the automobile with initial velocity U = 0 at a constant acceleration of 1.96 m/s². Because the police is starting from rest.

For the automobile, let us use first equation of motion

V = U - at.

Acceleration a is negative since it is decelerating with a = 3.05 m/s² . And

V = 0.

Substitute U and a into the formula

0 = 15.65 - 3.05t

15.65 = 3.05t

t = 15.65/3.05

t = 5.13 seconds

But 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.

The total time required for the police car to overtake the automobile will be

12 + 5.13 = 17.13 seconds.

b.) Using the third equation of motion formula for the police car at V = 11.18 m/s and a = 1.96 m/s²

V^2 = U^2 + 2aS

Where S = distance travelled.

Substitute V and a into the formula

11.18^2 = 0 + 2 × 1.96 ×S

124.99 = 3.92S

S = 124.99/3.92

S = 31.88 m

c.) The speed of the police car at the time it overtakes the automobile will be in line with the speed zone which is 11.18 m/s

d.) That will be the final velocity V of the automobile car.

We will use third equation of motion to solve that.

V^2 = U^2 + 2as

V^2 = 15.65^2 - 2 × 3.05 × 31.88

V^2 = 244.9225 - 194.468

V = sqrt( 50.4545)

V = 7.1 m/s

Explanation:

Short-circuiting transfer is a mode of metal transfer in welding where low currents are used to allow the liquid metal at the electrode tip to be transferred by surface tension to the molten weld pool. The low current causes the metal to form small droplets that are moved from the electrode tip to the weld pool by the surface tension of the molten metal. This mode of transfer is characterized by a short arc length and a high frequency of droplet formation. It results in a low heat input into the workpiece and a lower probability of weld defects compared to other transfer modes such as spray transfer.

This question is incomplete, the missing diagram is uploaded along this answer below.

Answer:

the forces required to keep the artery in place is 1.65 N

Explanation:

Given the data in the question;

Inlet velocity V₁ = 50 cm/s = 0.5 m/s

diameter d₁ = 15 mm = 0.015 m

radius r₁ = 0.0075 m

diameter d₂ = 11 mm = 0.011 m

radius r₂ = 0.0055 m

A₁ = πr² = 3.14( 0.0075 )² =  1.76625 × 10⁻⁴ m²

A₂ = πr² = 3.14( 0.0055 )² =  9.4985 × 10⁻⁵ m²

pressure at inlet P₁ = 110 mm of Hg = 14665.5 pascal

pressure at outlet P₂ = 95 mm of Hg = 12665.6 pascal

Inlet volumetric flowrate = A₁V₁ = 1.76625 × 10⁻⁴ × 0.5 = 8.83125 × 10⁻⁵ m³/s

given that; blood density is 1050 kg/m³

mass going in m' = 8.83125 × 10⁻⁵ m³/s × 1050 kg/m³ = 0.092728 kg/s

Now, using continuity equation

A₁V₁ = A₂V₂

V₂ = A₁V₁ / A₂ = (d₁/d₂)² × V₁

we substitute

V₂ =  (0.015 / 0.011 )² × 0.5

V₂ = 0.92975 m/s

from the diagram, force balance in x-direction;

0 - P₂A₂ × cos(60°) + Rₓ = m'( V₂cos(60°) - 0 )    

so we substitute in our values

0 - (12665.6 × 9.4985 × 10⁻⁵)  × cos(60°) + Rₓ = 0.092728( 0.92975 cos(60°) - 0 )    

0 - 0.6014925 + Rₓ =  0.043106929 - 0

Rₓ = 0.043106929 + 0.6014925

Rₓ = 0.6446 N

Also, we do the same force balance in y-direction;

P₁A₁ - P₂A₂ × sin(60°) + R\(_y\) = m'( V₂sin(60°) - 0.5 )  

we substitute

⇒ (14665.5 × 1.76625 × 10⁻⁴) - (12665.6 × 9.4985 × 10⁻⁵) × sin(60°) + R\(_y\) = 0.092728( 0.92975sin(60°) - 0.5 )

⇒ 1.5484 + R\(_y\) = 0.092728( 0.305187 )

⇒ 1.5484 + R\(_y\) = 0.028299    

R\(_y\) = 0.028299 - 1.5484

R\(_y\) = -1.52 N

Hence reaction force required will be;

R = √( Rₓ² + R\(_y\)² )

we substitute

R = √( (0.6446)² + (-1.52)² )

R = √( 0.41550916 + 2.3104 )

R = √( 2.72590916 )

R = 1.65 N

Therefore, the forces required to keep the artery in place is 1.65 N

Hello there!

In this case, according to the given information, it turns out possible for us to set up an energy balance for the turbine's inlets and outlets:

\(m_{in}h_{in}=W_{out}+m_{out}h_{out}\)

Whereas the mass flow is just the same, which means we have:

\(W_{out}=m_{out}(h_{out}-h_{in})\)

And the enthalpy and entropy of the inlet stream is obtained from steam tables:

\(h_{in}=1860.7BTU/lbm\\\\s_{in}= 2.2096BTU/lbm-R\)

Now, since we assume the 80% accounts for the isentropic efficiency for this adiabatic gas turbine, we assume the entropy is constant so that:

\(s_{out}= 2.2096BTU/lbm-R\)

Which means we can find the temperature at which this entropy is exhibited at 15 psia, which gives values of temperature of 1200 °F (s=2.1986 BTU/lbm-K) and 1400 °F (s=2.2604 BTU/lbm-K), and thus, we interpolate for s=2.2096 to obtain a temperature of 1235.6 °F.

Moreover, the enthalpy at the turbine's outlet can be also interpolated by knowing that at 1200 °F h=1639.8 BTU/lbm and at 1400 °F h=174.5 BTU/lbm, to obtain:

\(h_{out}=1659.15BUT/lbm\)

Then, the isentropic work (negative due to convention) is:

\(W_{out}=2500lbm/h(1659.15BUT/lbm-1860.7BUT/lbm)\\\\W_{out}=-503,875BTU\)

And the real produced work is:

\(W_{real}=0.8*-503875BTU\\\\W_{real}=-403100BTU\)

Finally, in horsepower:

\(W_{real}=-403100BTU/hr*\frac{1HP}{2544.4336BTU/hr} \\\\W_{real}=158.4HP\)

Energy = Force * Displacement

Replacing these variables, with their S.I units:

Joule = Newton*m

where,

Force (Newton) = mass (kg) * acceleration (m/s²)

Newton = kg.m/s²

Therefore,

Note that with respect to the prompt on wiring, Option C, "the service legs are out of phase," is the correct answer.

In a three-wire 120 V system, there are two "hot" wires that are 180 degrees out of phase with each other and one neutral wire. The voltage between each hot wire and the neutral wire is 120 V. However, the voltage between the two hot wires is 240 V, which is twice the voltage between a hot wire and the neutral wire.

This is because the two hot wires are out of phase with each other. When one hot wire is at its maximum positive voltage, the other hot wire is at its maximum negative voltage. Therefore, the voltage difference between the two hot wires is the sum of their individual voltages, which is 240 V.

So, the correct statement is that the 240 V in a three-wire 120 V system is due to the service legs being out of phase.
