You would require an extension ladder with an extension of about 7 meters for a two-story residence. The short answer is no, leaning a ladder against a gutter is not safe. "For a leaning ladder, you should secure it and have a sturdy top resting point, i.e. do not rest a ladder against weak upper surfaces." It is not a good idea to lean your ladder against a gutter as the gutter could not be strong enough to hold it.

The unknown capacitor in arm CD must have a value of 330 microfarads, and the unknown resistor must have a value of 100 kilo-ohms.

To solve the problem, use the following formula:
Cseries = C1 x C2 / (C1 + C2)

Where C1 is the value of the capacitor in arm AB (47 microfarads) and C2 is the value of the capacitor in arm BC (330 microfarads).

Therefore, Cseries = 330 microfarads.

Also, the total resistance of arms CD is the sum of the resistance of the resistor (R) and the reciprocal of the capacitive reactance of the capacitor (1/Xc).

Using the following formula:
Rtotal = R + 1/Xc

Where Xc = 1/2πfC,

f is the frequency and C is the capacitance.

For this problem,

Xc = 1/2π(50)(330 x 10-6)

=> 100 kilo-ohm.

Mechanical combustion results from all of the following, except: Electrical lighting.

Electric lighting has been a part of popular culture since Thomas Edison created a usable incandescent bulb in 1879. It was a major draw at the world's fairs in Chicago in 1894, Buffalo in 1901, and St. Louis in 1904, for instance.

Cities became more hospitable at night thanks to electric lighting; for instance, Broadway earned the nickname the Great White Way thanks to it. Moreover, it added brightness and life to homes.

Unsurprisingly, electric lighting was almost always referred to favorably in popular culture during the first half of the twentieth century. Take the 1931 film "City Lights" by Charlie Chaplin as an illustration. It celebrated indoor and outdoor electric lighting.

The output image with padding will be as follows:1 2 3 4 4 5 7 8 9.

In order to apply the smoothing for 3x3 sized image matrix x with the kernel h of size 3×3, shown below in Figure 1, the steps involved are as follows:First, the matrix needs to be padded. It is assumed that we are applying a zero padding, which adds a border of zeros around the original matrix. For instance, for a 3x3 matrix, we would end up with a 5x5 matrix.Second, we apply the kernel h to each of the individual pixels in the matrix. The kernel is a set of values that we will apply to each pixel in the image. Each element of the kernel will be multiplied by the corresponding pixel in the image. The result of each of these multiplications will be summed up, and that sum will be placed in the output matrix.

The original image is of size 3x3, which is too small for many applications. In order to apply the kernel, we first need to pad the image. The padded image will be 5x5 in size. The kernel is also of size 3x3, and it will be applied to each pixel in the image. The kernel is shown below in Figure 1.Figure 1 The pixel values in the original image are as follows:Original 1 2 35 6 47 8 9The padded image will be as follows:0 0 0 0 0 01 2 3 5 6 40 0 0 0 0 07 8 9 0 0 0

We will apply the kernel to each of the individual pixels in the image. The kernel is shown below in Figure 1.0 1 0 1 0 1 0 1 0

We will apply the kernel to each pixel by multiplying each element in the kernel by the corresponding pixel in the image. For instance, the pixel value in the output image at position (2, 2) will be the result of the following calculation:(0 × 1) + (1 × 2) + (0 × 3) + (1 × 5) + (0 × 6) + (1 × 4) + (0 × 7) + (1 × 8) + (0 × 9) = 26

An extremum is a point where the function has its highest or lowest value, and at which the slope is zero.

The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum is as follows;

Reason:

The given parameters are;

Form of silo = Cylinder surmounted by a hemisphere

Cost of construction of hemisphere per square unit = 2 × The cost of of construction of the cylindrical side wall

Required:

The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum

Solution:

The fixed volume of the silo, V, can be expressed as follows;

\(V = \pi \cdot r^2 \cdot h + \dfrac{2}{3} \cdot \pi \cdot r^3\)

Where;

h = The height of the cylinder

r = The radius of the cylinder

The surface area is, Surface Area = 2·π·r·h + 2·π·r²

The cost, C = 2·π·r·h + 2×2·π·r² = 2·π·r·h + 4·π·r²

Therefore;

\(C = 2 \times \pi \times r\times \dfrac{V - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } + 4 \cdot \pi \cdot r^2 = \dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r}\)

At the minimum value, we have;

Which gives;

16·π·r³ = 6·V

Which gives;

\(h = \dfrac{\dfrac{8 \cdot \pi \cdot r^3}{3} - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } = 2 \cdot r\)

h = 2·r

The height of the silo, h = 2 × The radius, 2

Therefore, the dimensions to be used if the volume is fixed and the cost is to be kept to a minimum is, height, h = 2 times the radius

With assumption of a stripping factor of 2.5 , The value of the theoretical air flow rate is 8.3 L/min

The dimensionless form of Henry's law constant is:KH = H / (RT)

Where H is Henry's law constant (5.5 x 10-4 atm-m3/mole), R is the universal gas constant (0.0821 L atm / mole K), and T is the absolute temperature (25°C = 298 K)

KH = (5.5 x 10-4 atm-m3/mole) / (0.0821 L atm / mole K x 298 K) = 2.12 x 10-6 mole fraction/m3atm

The air flow rate can be calculated using the following formula:

Qa = (Qw × KH × L) / (SF × (Ya - Yw))

Where Qw is the water flow rate (850 m3/day), KH is the dimensionless Henry's law constant (2.12 x 10-6 mole fraction/m3atm), L is the tower height (unknown), SF is the stripping factor (2.5), Ya is the air benzene concentration (unknown), and Yw is the water benzene concentration (8 mg/L or 8 x 10-6 g/L).

Rearranging the equation to solve for L:L = (Qa × SF × (Ya - Yw)) / (Qw × KH) = (Qa × 2.5 × (Ya - 8 x 10-6)) / (850 × 2.12 x 10-6)

Theoretical air flow rate can be determined from the equation.

Hello! In this question, we are trying to find the maximum value of shear flow in the web of the wing spar. Note that we are trying to find this with a section that is 1 meter away from the free end of the beam.
__________________________________________________________

Explanation:

In this problem, we know that:

This information should be kept in mind and can help us solve our problem.

__________________________________________________________

Solve:

Let us begin to solve the problem.

Since we're analyzing the moment in one section, in this case, we can note this as "section 1", we can use this formula to determine the moment in this section:

\(M_{1}=\frac{wl^2}2}\)
Whereas:

Plug in the values into the equation and solve:

\(M_{1}=\frac{15*1^2}2}=7.5\text{kN-m}\)
Now, let us find the moment of inertia of the beam in our 1st section. We'll use the formula:

\(I_{xx}=\frac{BD^3}{12} +2Ah^2\)

Whereas:

Plug in the values into the equation and solve:

\(I_{xx}=\frac{2(300)^3}{12} +2(500)(150)^2=2.7\times10^7\:\text{mm}^4\)
Now knowing our moment and inertia, we can solve our direct distress in the z direction of our flanges using the following formula:

\(\sigma_{z,U} = -\sigma_{z,L}=\frac{M_{1}}{I_{xx}}y\)
We know:

Plug the values into the equation and solve. (Note that unit conversion was done for M1):

\(\sigma_{z,U} = -\sigma_{z,L}=\frac{7.5\text{kN-m}*(\frac{1000 N}{1kN})(\frac{1000mm}{1m} )}{2.7\times10^7}(150mm)=-41.7\:\text{N/mm}^2\)
Since we now know what our direct distress is, we can find the bending moment resultant with the formula:

\(P_{z,U}=\sigma_{z,U}\times A\)

We know:

Plug in the values to our equation and solve:

\(P_{z,U}=-41.7\:\text{N/mm}^2\times 500\:mm^2=-20850\:N\)
Now knowing our bending moment resultant, we can now find our flange load of the web section. Note that our flange load is uniformly distributed. We will use the formula:

\(P_{U}=\sqrt{P_{z,U}^2+P_{y,U}^2}}\)
We know that:

Plug in the values into the equation and solve:
\(P_{U}=\sqrt{(-20850)^2+0^2}}=20850\:N\)
Please note that the answer we calculated above is our tension (T).

Let's now calculate our bending moment resultant using:

\(P_{y,L}=P_{z,L}\times\frac{\delta{y}^2}{\delta_{z}}\)

We know:

Plug in the values and solve. To make things go faster, I included the unit conversion for our denominator value:

\(P_{y,L}=-20850\:N\times\frac{100\:mm}{(1\:m\times\frac{1000\:mm}{1\:m} )}=-2085\:kN=2085\:kN\)
Please note that the above calculation would be our compression value.

Let's calculate our shear force in the web in our 1st section using a known relationship:

\(S_{y}=-W\times\delta_{z}+P_{y,L}\)
We know:

Plug in our known values and solve:

\(S_{y}=-15\times(1\:m\times\frac{1000\:mm}{1\:m} )+2085=-12915\:N\)

In order to figure out what our shear flow is (note that our shear flow is represented as q), we will use the relationship:

\(q=\frac{S_y}{I_{xx}} [\int_{0}^{s}2(150-s)ds+500\times(\frac{300}{2} )]\)

We know:

Plugging in the values, we will get:

\(q=\frac{12915}{2.7\times10^7\:mm} [\int_{0}^{s}2(150-s)ds+500\times(\frac{300}{2} )]\)

Simplify the equation:

\(q=4.78\times10^{-4} [\int_{0}^{s}(300-s)ds+75000]\)
Integrate the equation:

\(q=4.78\times10^{-4} [\int_{0}^{s}(300-s)ds+75000]\\\\q=4.78\times10^{-4} ((300s-\frac{2s^2}{2} +[0])+75000)\\\\q=4.78\times10^{-4} ((300s-s^2 )+75000)\)

We now have our equation for the shear flow. We know that the max value of shear flow will happen when s equals 150 mm, so let's plug in the value 150 mm into "s" in our "q" equation and solve:

\(q=4.78\times10^{-4} ((300(150)-150^2 )+75000)=\boxed{46.8\:N/mm}\)

__________________________________________________________

Answer:

The max value of shear flow in the web in the 1st section of the beam is:

\(q=\boxed{46.8\:N/mm}\)

The couple of the moment of the two forces is 3.82 N.m

We are given;

Force applied at A; F_a = 62 N

Force applied at C; F_c = 62 N

AB = BC = 200 mm = 0.2 m

Horizontal component of  F_a is; F_ax = 62 cos 50

Vertical component of  F_a is; F_ay = 62 sin 50

Horizontal component of  F_c is; F_cx = 62 cos 50

Vertical component of  F_c is; F_cy = 62 sin 50

Taking moments about point C gives;

M_c = F_ay * AB - F_ax * BC

M_c = (62 sin 50 * 0.2) - (62 cos 50 * 0.2)

M_c = 23.75 - 19.93

M_c = 3.82 N.m

Answer:

When are resistors in series? Resistors are in series whenever the flow of charge, called the current, must flow through devices sequentially. For example, if current flows through a person holding a screwdriver and into the Earth, then  

R

1

 in Figure 1(a) could be the resistance of the screwdriver’s shaft,  

R

2

 the resistance of its handle,  

R

3

 the person’s body resistance, and  

R

4

 the resistance of her shoes.

Figure 2 shows resistors in series connected to a voltage source. It seems reasonable that the total resistance is the sum of the individual resistances, considering that the current has to pass through each resistor in sequence. (This fact would be an advantage to a person wishing to avoid an electrical shock, who could reduce the current by wearing high-resistance rubber-soled shoes. It could be a disadvantage if one of the resistances were a faulty high-resistance cord to an appliance that would reduce the operating current.)

Two electrical circuits are compared. The first one has three resistors, R sub one, R sub two, and R sub three, connected in series with a voltage source V to form a closed circuit. The first circuit is equivalent to the second circuit, which has a single resistor R sub s connected to a voltage source V. Both circuits carry a current I, which starts from the positive end of the voltage source and moves in a clockwise direction around the circuit.

Figure 2. Three resistors connected in series to a battery (left) and the equivalent single or series resistance (right).

To verify that resistances in series do indeed add, let us consider the loss of electrical power, called a voltage drop, in each resistor in Figure 2.

According to Ohm’s law, the voltage drop,  

V

, across a resistor when a current flows through it is calculated using the equation  

V

=

I

R

, where  

I

 equals the current in amps (A) and  

R

 is the resistance in ohms  

(

Ω

)

. Another way to think of this is that  

V

 is the voltage necessary to make a current  

I

 flow through a resistance  

R

.

So the voltage drop across  

R

 is  

V

712.5 rpm

Explanation:

Given data:

number of poles = 4

percentage of full load torque = 200%

Calculate how fast in RPMs a typical NEMA class B motor shaft will rotate

assuming a frequency of ; 50 Hz

number of poles = 4

\(N_{s} = \frac{120 *50}{4}\) =  1500 rpm

For an Induction  Class B motor it has a maximum slippage of 5%

therefore the operating speed = 0.95 * 1500 = 1425 rpm

Note ; An induction motor load torque is inversely proportional to its speed hence a t 200% of full load torque the speed in RPM at which the class B motor shaft will rotate = 1425 / 2 = 712.5

The question is incomplete. The complete question is :

The hydrofoil boat has an A-36 steel propeller shaft that is 100 ft long. It is connected to an in-line diesel engine that delivers a maximum power of 2590 hp and causes the shaft to rotate at 1700 rpm . If the outer diameter of the shaft is 8 in. and the wall thickness is \($\frac{3}{8}$\)  in.

A) Determine the maximum shear stress developed in the shaft.

\($\tau_{max}$\) = ?

B) Also, what is the "wind up," or angle of twist in the shaft at full power?

\($ \phi $\) = ?

Solution :

Given :

Angular speed, ω = 1700 rpm

                              \($ = 1700 \frac{\text{rev}}{\text{min}}\left(\frac{2 \pi \text{ rad}}{\text{rev}}\right) \frac{1 \text{ min}}{60 \ \text{s}}$\)

                              \($= 56.67 \pi \text{ rad/s}$\)

Power \($= 2590 \text{ hp} \left( \frac{550 \text{ ft. lb/s}}{1 \text{ hp}}\right)$\)

          = 1424500 ft. lb/s

Torque, \($T = \frac{P}{\omega}$\)

                 \($=\frac{1424500}{56.67 \pi}$\)

                 = 8001.27 lb.ft

A). Therefore, maximum shear stress is given by :

Applying the torsion formula

\($\tau_{max} = \frac{T_c}{J}$\)

        \($=\frac{8001.27 \times 12 \times 4}{\frac{\pi}{2}\left(4^2 - 3.625^4 \right)}$\)

      = 2.93 ksi

B). Angle of twist :

     \($\phi = \frac{TL}{JG}$\)

         \($=\frac{8001.27 \times 12 \times 100 \times 12}{\frac{\pi}{2}\left(4^4 - 3.625^4\right) \times 11 \times 10^3}$\)

         = 0.08002 rad

         = 4.58°
