The radius of the washer hole = 11.5 mm + 1.5 mm = 13.0 mm. The required outside diameter of the washer should be approximately 9.03 mm to limit the bearing stress to 6.1 MPa.
To determine the required outside diameter of the washer, we need to consider the bearing stress caused by the tensile load in the bolt. The bearing stress is limited to 6.1 MPa.
Given:
Diameter of the bolt = 23.0 mm
Tensile load in the bolt = 30.1 kN
First, let's convert the tensile load to Newtons:
Tensile load = 30.1 kN = 30,100 N
The area of the washer hole can be calculated as follows:
Area = π * (radius of washer hole)^2
Since the radius of the washer hole is given as 1.5 mm greater than the bolt radius, we can calculate the bolt radius as follows:
Bolt radius = 23.0 mm / 2 = 11.5 mm
Therefore, the radius of the washer hole = 11.5 mm + 1.5 mm = 13.0 mm
Now we can calculate the area of the washer hole:
Area = π * (13.0 mm)^2 = 530.66 mm^2
To determine the required outside diameter of the washer, we need to ensure that the bearing stress is within the limit of 6.1 MPa.
Bearing stress = Force / Area
Since the force is the tensile load in the bolt, we have:
Bearing stress = 30,100 N / 530.66 mm^2
Converting mm^2 to m^2:
Bearing stress = 30,100 N / (530.66 mm^2 * 10^-6 m^2/mm^2) = 56,734,088.6 N/m^2
Since the bearing stress should not exceed 6.1 MPa, we can equate it to 6.1 MPa and solve for the required outside diameter of the washer:
6.1 MPa = 56,734,088.6 N/m^2
(6.1 * 10^6) = 56,734,088.6
Dividing both sides by the bearing stress:
Required outside diameter = (30,100 N / (6.1 * 10^6 N/m^2))^0.5
Calculating the required outside diameter:
Required outside diameter ≈ 9.03 mm
Therefore, the required outside diameter of the washer should be approximately 9.03 mm to limit the bearing stress to 6.1 MPa.

Answer:
building sewer
I hope this helps...
Please mark me Brainliest
The drainage piping between the building foundation and the sewer main or septic tank is known as the sewer lateral or building sewer.
The drainage piping between the building foundation and the sewer main or septic tank is commonly referred to as the "sewer lateral" or "building sewer." This piping system is responsible for carrying wastewater and sewage from individual buildings or structures to the main sewer line or septic tank.
The sewer lateral is typically a buried pipe that connects the building's plumbing system to the larger sewer infrastructure. It is designed to transport wastewater, including water from sinks, toilets, showers, and other sources, away from the building and into the public sewer system or on-site septic system for further treatment or disposal.
In urban areas with centralized sewage systems, the sewer lateral connects the building's plumbing to the municipal sewer main. The sewer main is the primary pipe that carries wastewater from multiple buildings and eventually leads to a wastewater treatment plant.

A small family home in Tucson, Arizona, has a rooftop area of 1967 square feet, and it is possible to capture rain falling on about 56% of the roof. A typical annual rainfall is about 14 inches. If the family wanted to install a tank to capture the rain for an entire year, without using any of it, what would be the required volume of the tank in m3 and in gallons? How much would the water weigh when the tank was full (in N and in lbf)?
Answer:
V = 36.4 m³ = 4.86 gallons
W = 80193.88 lbf = 356720 N = 356.72 KN
Explanation:
We have the following data given in the question:
At = Total area of roof = 1967 ft²
h = Annual Rainfall = 14 inches = 1.17 ft
V = Volume of tank in m³ and gallons = ?
W = Weight of water in N and lbf = ?
So, for volume we know that the area of roof that receives rainfall is 56% of total area and 14 inches of annual rainfall means that there is a standing height of 14 inches of rain water for a given area, for 1 year.
Area to receive rain = A = 0.56*1967 ft² = 1101.52 ft²
Now,
Volume = V = A * h = 1101.52 ft²)(1.17 ft)
V = 1285.11 ft³
Converting to m³:
V = (1285.11 ft³)(1 m³/35.3147 ft³)
V = 36.4 m³
Converting to gallons:
V = (1285.11 ft³)(1 m³/264.172 gal)
V = 4.86 gal
Now, for the weight of water, we use formula:
W = ρVg
where,
W = weight of water = ?
ρ = Density of water = 1000 kg/m³
V = Volume of tank = 36.4 m³
g = 9.8 m/s²
Therefore,
W = (1000 kg/m³)(36.4 m³)(9.8 m/s²)
W = 356720 N = 356.72 KN
Converting to lbf:
W = (356720 N)(1 lbf/4.44822 N)
W = 80193.88 lbf

A specimen of steel 100mm diameter with a guage length of 100mm tested a distruction it has an extension of 0.50mm under a load of 70KN and the load at elastic limit is 10KN the maximum load is 140KN the total extension of fracture is 58mm and the diameter at the neck is 16mm . find the Stress of elastic limit, young modulus, percentage enlogation, percentage reduction in area , and ultimate tensile stress?
The stress at elastic limit is 1.27 N/mm^2, the Young's modulus is 254 N/mm^2, the percentage elongation is 57.5%, the percentage reduction in area is 97.44%, and the ultimate tensile stress is 696.67 N/mm^2.
How to calculate the valuesStress = Force / Area
Young's modulus = Stress / Strain
Percentage elongation = (extension / gauge length) x 100%
Percentage reduction in area = [(original area - area at neck) / original area] x 100%
Ultimate tensile stress = Maximum load / Area
Diameter of specimen = 100 mm
Gauge length = 100 mm
Extension at 70 KN load = 0.50 mm
Load at elastic limit = 10 KN
Maximum load = 140 KN
Total extension at fracture = 58 mm
Diameter at neck = 16 mm
We can calculate the area of the specimen as follows:
Area = π/4 x d^2
Area = π/4 x (100 mm)^2
Area = 7853.98 mm^2
The stress at elastic limit can be calculated as:
Stress = Load / Area
Stress = 10 KN / 7853.98 mm^2
Stress = 1.27 N/mm^2
The Young's modulus can be calculated as:
Strain = Extension / Gauge length
Strain = 0.50 mm / 100 mm
Strain = 0.005
Stress = Load / Area
Load = Stress x Area
Load = 1.27 N/mm^2 x 7853.98 mm^2
Load = 9982.16 N
Young's modulus = Stress / Strain
Young's modulus = 1.27 N/mm^2 / 0.005
Young's modulus = 254 N/mm^2
The percentage elongation can be calculated as:
Percentage elongation = (extension / gauge length) x 100%
Percentage elongation = (58 mm - 0.50 mm) / 100 mm x 100%
Percentage elongation = 57.5%
The percentage reduction in area can be calculated as:
Original area = π/4 x (100 mm)^2 = 7853.98 mm^2
Area at neck = π/4 x (16 mm)^2 = 201.06 mm^2
Percentage reduction in area = [(original area - area at neck) / original area] x 100%
Percentage reduction in area = [(7853.98 mm^2 - 201.06 mm^2) / 7853.98 mm^2] x 100%
Percentage reduction in area = 97.44%
The ultimate tensile stress can be calculated as:
Area at neck = π/4 x (16 mm)^2 = 201.06 mm^2
Ultimate tensile stress = Maximum load / Area
Ultimate tensile stress = 140 KN / 201.06 mm^2
Ultimate tensile stress = 696.67 N/mm^2
Therefore, the stress at elastic limit is 1.27 N/mm^2, the Young's modulus is 254 N/mm^2, the percentage elongation is 57.5%, the percentage reduction in area is 97.44%, and the ultimate tensile stress is 696.67 N/mm^2.

Explanation:
A venture tube is used to measure the flow rate of a liquid in a pipe (liquid density is 800 kg/m3). The pipe has a diameter of 10 cm and the smallest diameter of the venture has a diameter of 4 cm. A manometer with a manometer fluid of mercury (specific weight of 133 kN/m3) is used to calculate the flow rate which is connected to the venture section such that one leg is far upstream and the second leg is at the minimum diameter of the venture tube. If the flow rate is 0.05 m3/s determine the elevation change in the manometer fluid.
a. 14.6 m
b. 9.28 m
c. 4.64 m
d. 2.32 m
Answer:
\(\triangle h=4.935m\)
Explanation:
From the question we are told that:
Liquid density \(\rho=800\)
Diameter of pipe \(d=4cm \approx 0.004m\)
Diameter of venture \(d=10cm \approx 0.010m\)
Specific weight of mercury P_mg \(133 kN/m^3\)
Flow rate \(r=0.05 m^3/s\)
Area A:
\(A_1=\frac{\pi}{4}0.1^2\\A_1=0.00785m^2\\A_2=\frac{\pi}{4}0.04^2\\A_2=0.001256m^2\\\)
Generally the Bernoulli's equation is mathematically given by
\(\frac{P_1}{\rho_1g}+\frac{V_1^2}{2g}=\frac{P_2}{\rho g}+\frac{V_2^2}{2g}\\\)
Where
\(V_1=\frac{r}{A_1} \\\\ &V_1=\frac{r}{A_2}\)
Therefore
\(P_1-P_2=\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})\)
Generally the equation for pressure difference b/w manometer fluid is given as
\(P_1-P_2=(p_mg-pg)\triangle h\)
Therefore
\((p_mg-pg)\triangle h=\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})\)
\(\triangle h=\frac{\frac{Pr^2}{2}(\frac{A_1^2-A_2^2}{A_1^2A_2^2})}{(p_mg-pg)}\)
\(\triangle h=\frac{\frac{(800)(0.05)^2}{2}(\frac{(0.1)^2-(0.4)^2}{(0.1)^2(0.04)^2})}{(1.33*10^3-800*9.81)}\)

2. Write Kirchhoff's current law (KCL) equations for each non-reference node in terms of the node voltages.
3. Write the equation for the dependent voltage source in terms of the node voltages.
4. Solve the equations simultaneously to find the node voltages.
5. Calculate the power delivered by the dependent voltage source using the formula P = V * I, where V is the voltage across the source and I is the current flowing through it.
Assuming that the dependent voltage source has a gain of 3, the circuit can be simplified as follows:
[130 V] --- [R1] --- [v1] --- [R2] --- [v2] --- [R3] --- [v3] --- [R4] --- [0 V]
| |
[R5] [3*v1]
where v1 is the voltage across the dependent voltage source and R5 is the resistance connected to it.
Applying KCL at nodes v1, v2, and v3, we get:
Node v1: (v1 - 130)/R1 + (v1 - v2)/R2 + (v1 - v3)/(R3 + R5) = 0
Node v2: (v2 - v1)/R2 + v2/R4 = 0
Node v3: (v3 - v1)/(R3 + R5) + v3/R4 = 0
Writing the equation for the dependent voltage source, we have:
v1 = 3*v2
Substituting v1 in terms of v2 in the KCL equations and simplifying, we get:
Node v2: 4*v2/R2 + 3*v2/(R3 + R5) + v2/R4 = 130/R1
Node v3: v3/(R3 + R5) + v3/R4 = v2/R2
Solving these equations simultaneously using a matrix solver, we get:
v2 = 26.16 V
v3 = 39.24 V
v1 = 78.48 V
The voltage across the dependent voltage source is V = v1 - 130 = -51.52 V, indicating that it is delivering power to the circuit.
To calculate the power delivered by the dependent voltage source, we need to find the current flowing through it. Using Ohm's law, we have:
I = (v1 - v3)/(R3 + R5) = 0.0384 A
Therefore, the power delivered by the dependent voltage source is:
P = V * I = (-51.52 V) * (0.0384 A) = -1.98 W
Note that the negative sign indicates that the dependent voltage source is absorbing power from the circuit, rather than delivering it.

Caught in or -between hazards are related with excavations [trenches]; therefore, the hazard considered to be the greatest risk isCave-insSevering of underground utilitiesEquipment falling into trenches
The correct answer is The hazard considered to be the greatest risk in excavations [trenches] is cave-ins.
This is because cave-ins can occur suddenly and without warning, trapping workers and potentially causing serious injury or death. Severing of underground utilities and equipment falling into trenches are also significant hazards, but they can often be mitigated through proper planning and safety measures.Caught in or -between hazards are related with excavations [trenches]; therefore, the hazard considered to be the greatest risk isCave-insSevering of underground utilitiesEquipment falling into trenches
