A retaining walL with a smooth vertical bar retains a soil mass having a horizontal surface to depth of 5.4 meters . calculate the magnitude of the resultant active thrust on the wall and give its line of action . the soil has an angle of shearing resistance of 30 and unit weight of 19.8KN per cubic meter
Answers
Note that the magnitude of the resultant active thrust on the wall is 876.69 kN.
What is the explanation for the above response?
To calculate the magnitude of the resultant active thrust on the wall, we need to use Rankine's theory of earth pressure.
Let's assume that the wall height is also 5.4 meters, and the angle of wall friction is zero.
Then, the total active thrust (Q) is given by:
Q = Ka * H * gamma * H/2
Where,
Ka = Active earth pressure coefficient
H = height of the wall
gamma = unit weight of soil
The active earth pressure coefficient can be calculated using the following formula:
Ka = (1 - sin(phi)) / (1 + sin(phi))
Where, phi = angle of shearing resistance of soil
Substituting the given values, we get:
phi = 30 degrees
H = 5.4 meters
gamma = 19.8 kN/m^3
Ka = (1 - sin(30)) / (1 + sin(30)) = 1/3
Q = Ka * H * gamma * H/2 = (1/3) * 5.4 * 19.8 * 5.4/2 = 876.69 kN
Therefore, the magnitude of the resultant active thrust on the wall is 876.69 kN.
The line of action of the resultant active thrust on the wall will be at one-third of the height of the wall from the bottom. Therefore, the line of action of the active thrust will be at a height of 1.8 meters from the bottom of the wall.

column and with bending? How could you say that it is safe?
Answers
The design criteria and process in designing of a steel base plate for axially loaded column and with bending involve several steps. The design of the base plate should be considered in terms of strength, stiffness, and durability.
Step 1: The design of the base plate requires the determination of column loads and reactions. This includes the axial load and bending moment at the base of the column. It is important to consider the column's shape, size, and material to determine the load it can withstand.
Step 2: The thickness of the base plate is calculated based on the loads and reactions at the base of the column. It is essential to consider the plate's stiffness and the stresses induced in it due to the loads.
Step 3: The plate's width and length are determined based on the column's shape and size, the loads acting on it, and the available space for the base plate.
Step 4: The bearing capacity of the foundation soil should be checked to ensure that it can support the loads induced by the column and the base plate. The soil type and its bearing capacity should be considered when designing the base plate.
The bearing capacity of the foundation soil should be sufficient to support the loads induced by the column and the base plate. the plate's yield strength and buckling resistance should be checked to ensure that it can withstand the loads and reactions acting on it.

Answers
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;
Height of cylinder = 2 × Radius of cylinderReason:
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;
\(V = \pi \cdot r^2 \cdot h + \dfrac{2}{3} \cdot \pi \cdot r^3\)
\(h = \dfrac{V - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 }\)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;
\(C = 2 \times \pi \times r\times \dfrac{V - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } + 4 \cdot \pi \cdot r^2 = \dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r}\)
\(C = \dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r}\)At the minimum value, we have;
\(\dfrac{dC}{dr} =0 = \dfrac{d}{dr} \left(\dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r} \right) = \dfrac{16 \cdot r^3 \cdot \pi - 6 \cdot V}{3 \cdot r^2}\)Which gives;
16·π·r³ = 6·V
\(V = \dfrac{16 \cdot \pi \cdot r^3}{6} = \dfrac{8 \cdot \pi \cdot r^3}{3}\)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

A batch of 5% of food product has a moisture content of 150% dry basis. Calculate how much water must be removed from this product to reduce it's moisture content to 20% wet basis
Answers
To reduce the moisture content of the batch of food product from 150% on a dry basis to 20% on a wet basis, we need to remove 1.225 times the weight of the original batch in water.
To solve this problem, we can use the concept of moisture content on a dry basis and moisture content on a wet basis.
Let's first convert the given moisture content of 150% on a dry basis to moisture content on a wet basis:
Moisture content on a wet basis = (Weight of water / Total weight of the product) x 100%
150% = (Weight of water / (Weight of dry solids + Weight of water)) x 100%
Solving for the weight of water, we get:
Weight of water = 1.5 x Weight of dry solids
Next, we need to find the weight of dry solids in the original batch of food product. Since the batch is 5% of the total product weight, we can assume that the total weight of the product is 100 / 5 = 20 times the weight of the batch. Therefore, the weight of dry solids in the original batch is:
Weight of dry solids = 0.95 x Total weight of the product
Now, we can calculate the weight of water in the original batch of food product:
Weight of water = 1.5 x (0.95 x Total weight of the product) = 1.425 x Total weight of the product
To reduce the moisture content to 20% on a wet basis, we need to remove some amount of water from the product. Let's assume that the final weight of the product remains the same as the original weight. Then, we can write:
Weight of water in the final product = 0.2 x Final weight of the product
The amount of water that needs to be removed from the original batch to achieve the desired moisture content can be calculated as:
Amount of water to be removed = Weight of water in the original batch - Weight of water in the final product
= 1.425 x Total weight of the product - 0.2 x Total weight of the product
= 1.225 x Total weight of the product

Answers
Strain refers to the deformation experienced by a material under applied force. Various types of strain include axial, bending, shear, torsional, buckling, and centrifugal strain. Strain is measured as the ratio of change in length to the original length.
The different types of strain are as follows:
Axial strain: An axial strain is defined as the deformation that occurs parallel to the applied load. Bending strain: The deformation caused in a straight beam due to the applied load is known as bending strain. Shear strain: The deformation that happens when a material is subjected to a force that is parallel to the surface area of the material is known as shear strain. Torsional strain: Torsional strain is defined as the deformation that occurs in a material due to a twisting force. Buckling strain: Buckling strain happens in a material when it is subjected to a compressive load that is too large. Centrifugal strain: Centrifugal strain is defined as the force that arises when a material is exposed to a centrifugal force.The types of strain are used in materials science to understand how a material reacts to external forces such as compression, tension, and shear.
The amount of deformation a material experiences due to an applied force is called strain. Strain is measured using the formula (change in length/original length).
The resulting value is dimensionless and is expressed in terms of percentage or decimal form. It is the ratio of change in length to the original length.

nd demo of reaper in Mahindra Yuvo 575 DI tractor
Answers
Answer:
Explanation:
It appears that you are trying to solve a problem involving an insulated rigid tank containing saturated liquid water and water vapor. To determine the volume of the tank, you will need to know the mass of the liquid water and the mass of the water vapor. The mass of the liquid water can be calculated by multiplying the mass of the water and vapor mixture by the fraction of the mixture that is liquid water (1.4 kg * 0.25 = 0.35 kg). The mass of the water vapor can be calculated by subtracting the mass of the liquid water from the total mass of the mixture (1.4 kg - 0.35 kg = 1.05 kg).
To determine the final temperature of the tank, you will need to know the amount of heat added to the tank by the electric resistor and the specific heat capacity of the water and water vapor mixture. The specific heat capacity is a measure of the amount of heat required to raise the temperature of a substance by a certain amount. The specific heat capacity of water is 4.186 J/g°C, and the specific heat capacity of water vapor is 2.080 J/g°C.
To determine the electric power rating of the resistor, you will need to know the amount of heat added to the tank by the resistor and the time over which the heat was added. The power rating of the resistor is equal to the amount of heat added to the tank divided by the time over which the heat was added.
I hope this helps clarify the problem and provide some guidance on how to solve it. If you have any further questions or need additional help, please don't hesitate to ask.

The current in an RLC circuit is described by d2i/dt2 + 10di/dt + 25 i = 0 If i(0) = 2 and di(0)/dt = 0, find i(t) for t > 0.
Answers
The current is i(t) = 2×\(e^{-5t}\)×cos(5t) for t > 0 in the given RLC circuit.
To find i(t) for t > 0 in the given RLC circuit, follow these steps:
1. Identify the given differential equation: d²i/dt² + 10di/dt + 25i = 0, with initial conditions i(0) = 2 and di(0)/dt = 0.
2. Recognize that the equation is a second-order linear homogeneous differential equation with constant coefficients.
3. Find the characteristic equation: r² + 10r + 25 = 0.
4. Solve for the roots of the characteristic equation. In this case, you will find that the roots are complex: r = -5 ± 5j.
5. Write the general solution for i(t) using the complex roots: i(t) = \(e^{-5t}\) × [A×cos(5t) + B×sin(5t)].
6. Apply the initial conditions to find the constants A and B:
i. i(0) = 2, so 2 = \(e^{0}\) × [A×cos(0) + B×sin(0)] → A = 2.
ii. di(0)/dt = 0, so 0 = -5 × \(e^{0}\) × [2×cos(0) + B×sin(0)] + \(e^{0}\) × [-2×sin(0) + 5B×cos(0)] → 5B = 0 → B = 0.
7. Substitute the values of A and B back into the general solution: i(t) = \(e^{-5t}\) × [2×cos(5t) + 0×sin(5t)].
Thus, i(t) = 2×\(e^{-5t}\)×cos(5t) for t > 0 in the given RLC circuit.
