Answer:

\(\mathbf{G_m = 2.25}\)

Explanation:

From the given information:

Let the weight of the mix in the air be = \(W_{ma}\)

Let the weight of the mix in water be = \(W_{mw}\); &

the bulk specific gravity be = \(G_m\)

SO;

\(W_{mw} = W_{ma} - v \delta _{w} --- (1)\)

Also;

\(G_m = \dfrac{W_{mw}}{v \delta_w} --- (2)\)

From (2), make\(v \delta_w\) the subject:

\(v \delta_w = \dfrac{W_{ma}}{G_m}\)

Now, equation (1) can be rewritten as:

\(W_{mw} = W_{ma} - \dfrac{W_{ma}}{G_m}\)

\(G_m = \dfrac{W_{ma}}{W_{ma} - W_{mw}}\)

Replacing the values;

\(G_m = \dfrac{1173.5}{1173.5 -652.5}\)

\(G_m = \dfrac{1173.5}{521}\)

\(\mathbf{G_m = 2.25}\)

Answer:

The main reason for bridges collapses is: earthquakes (natural disasters) and construction incidents. Whenever a natural disaster occur, it makes the bridge collapse. An example is hurricanes. Hurricanes come with a great wind and that might lead to the bridge collapsing. Construction incidents means the bridge falls during construction. Those who are employed in health, safety and environmental management need to make sure that during the construction, they have examined the material and made sure it is strong. Working with economists, they should seek better understanding of the methods for minimizing the costs during the life of the bridge. In case for natural disasters, like flooding, they should make the bridge in a lever where the water won't reach the bridge. And they should have a limit for weight in the bridges because that is another reason it collapses, because the bridge does not support extra weight.

Explanation:

True. If the rank of the augmented matrix of a system of n linear equations in n unknowns equals the rank of the matrix of coefficients, then the system has a unique solution. This is because the rank indicates the number of linearly independent rows, which determines the existence and uniqueness of the solution.

When solving a system of linear equations in n unknowns, the coefficients of the variables are organized into a matrix called the matrix of coefficients. The right-hand side of each equation is organized into a column vector, and the resulting augmented matrix is formed by appending this vector to the matrix of coefficients.

The rank of a matrix is the maximum number of linearly independent rows in the matrix. The rank of the augmented matrix is the same as the rank of the matrix of coefficients if and only if the system of equations has a unique solution.

This is because the rank of the matrix of coefficients indicates the number of equations that are independent of each other, while the rank of the augmented matrix indicates the number of equations that are independent of each other and also satisfy the right-hand side of the equation. If the ranks of both matrices are equal, then there is a one-to-one correspondence between equations and variables, and the system has a unique solution.

In other words, if the ranks are equal, there are exactly n linearly independent equations for n unknowns, and so there is a unique solution that satisfies all of the equations. If the ranks are not equal, then there are either no solutions or an infinite number of solutions.

proportional to the slip frequency. For an induction machine where the leakage inductance and stator losses can be ignored, the developed torque is proportional to the slip frequency.

An induction motor is a type of AC motor where the rotor is a cylindrical iron core with slots around the edge. When current is applied to the stator winding, a rotating magnetic field is produced, which induces current flow in the rotor.The rotor current generates a magnetic field in the rotor, which interacts with the magnetic field produced by the stator winding. This interaction causes the rotor to rotate. The speed of rotation depends on the difference between the synchronous speed of the magnetic field produced by the stator winding and the actual speed of the rotor.The difference between the synchronous speed and the actual speed is called the slip speed. The developed torque of the induction motor is proportional to the slip speed.  a: "proportional to the slip frequency"

The correct answer is option d.) 2500mm
The length of the belt in mm is 2500 mm.

Given that a belt is transmitting 50 kW power to a machine. The sheave has a diameter of 10 inches and turns at 1200 rpm, while the larger sheave turns at 500 rpm. To determine the length of the belt, we can use the formula for belt length:

Belt Length (L) = π (D1 + D2) / 2 + (2 × C)

Where:

For calculating the center distance, we use the formula:

C = √ (L² - ((D1 - D2) / 2)²)

Given:

Using the formula P = (2πNT) / 60, we can calculate the torque:

T = (50 × 10³ × 60) / (2π × 1200)

T = 78.54 Nm

Now, rearranging the formula for center distance, we get:

C = √ (L² - ((D1 - D2) / 2)²)

To find the center distance, we calculate the pitch diameter of the small sheave:

Diameter = 10 inches

Pitch diameter = 10 - (2 × 0.25) = 9.5 inches = 0.2413 m

Using the formula N1 / N2 = D2 / D1, we can find D2:

D2 = D1 × N1 / N2

D2 = 10 × 1200 / 500

D2 = 24 inches = 0.6096 m

Using the formula C = (D1 - D2) / 2, we calculate C:

C = (10 - 24) / 2

C = -7 inches = -0.1778 m

Now, we can calculate the length of the belt using the formula:

L = π (D1 + D2) / 2 + (2 × C)

L = π (10 + 24) / 2 + (2 × (-7))

L = 34π - 28

L = 106.814 mm

Hence, the length of the belt in mm is 106.814 mm, which is closest to 2500 mm. Therefore, the correct answer is 2500 mm.

Yes, to prevent falls when mounting the tractor, you should have at least one body part in contact with the tractor at one time.

The act of mounting a tractor involves stepping up onto the machine, which can pose a risk of falls if not done carefully. To prevent such accidents, it is recommended to always have at least one body part in contact with the tractor during the mounting process. This means maintaining contact with the tractor using a hand, foot, or any other body part while transitioning onto or off of it.

By having a point of contact with the tractor, you ensure stability and a secure base of support. This helps distribute your weight evenly and reduces the likelihood of slipping, losing balance, or falling. Additionally, keeping a body part in contact with the tractor provides a physical connection that can be used to steady yourself and make necessary adjustments during the mounting or dismounting process.

To prevent falls when mounting a tractor, it is crucial to maintain contact with the machine by having at least one body part in contact at all times. This simple precautionary measure significantly reduces the risk of accidents and ensures a safer experience when operating agricultural machinery. By following this guideline, operators can promote their well-being and minimize the potential for injuries during tractor usage.

To begin, let's break down the components of the npda m = ({q0, q1} , {a, b} , {a, z} , δ, q0, z, {q1}): {q0, q1} represents the set of states in the npda, with q0 being the initial state and q1 being the final (accepting) state. {a, b} represents the input alphabet, meaning the only valid symbols that can be read by the npda are "a" and "b".

First, we need to determine what the language accepted by the npda actually is. In other words, what strings of "a"s and "b"s will cause the npda to reach the accepting state q1? From the npda's definition, we can see that the only valid transitions are ones that involve pushing or popping "a"s or "z"s from the stack. This means that the npda is only able to recognize languages that have some sort of "balance" between "a"s and "z"s.
