The molecular weight of protein band A = 11,139 Da. The molecular weight of protein band B = 7,715 Da.

SDS-polyacrylamide gel electrophoresis (SDS-PAGE) and Gel Filtration (GF) on Sephadex G-200 are both techniques used to determine the molecular weight of a protein.

The molecular weight of proteins B and A can be calculated using the equation: Molecular weight (Da) = (Rm of protein band A/Rm of lysozyme) x 14,000. The Rm of protein band A is 0.562 and the Rm of lysozyme is 0.714. The molecular weight of protein band A= (0.562/0.714) x 14,000 = 11,139 Da.

The difference in the molecular weights obtained by the two techniques can be explained by the presence of protein aggregates, glycosylation, or disulphide bonds.

Gel Filtration on a Sephadex G-200 column under non-denaturing (native) conditions will give a molecular weight of 150,000 daltons, as it considers the molecular weight of the native protein and its tertiary structure.

The SDS-polyacrylamide gel electrophoresis experiment gives a molecular weight of the protein in its denatured form, thus the lower molecular weight obtained. Therefore, the protein is likely to have an overall higher molecular weight due to tertiary structure and other modifications.

From this data, it can be concluded that the protein has a complex tertiary structure with a high molecular weight due to possible modifications such as glycosylation or disulphide bonds. Additionally, the presence of aggregates and dimers can also increase molecular weight.

The given statement "Fatigue is defined as a failure caused by a repetitive or fluctuating stress that is much lower than that required to cause fracture on a single application of load" is true because the fatigue failure of materials subjected to cyclic loading is a slow and progressive process, culminating in the sudden and rapid growth of the crack to complete separation. So, the correct option is A.

The fatigue failure mode is the most common type of failure that occurs due to dynamic loading on metallic and nonmetallic materials. Fatigue failure is prevalent in almost all materials, including metals, non-metals, and composites. Although the materials possess sufficient strength, the presence of a flaw in the material can cause it to fail under fatigue loading. This type of failure occurs when the cyclic stresses generate microscopic cracks, which coalesce and lead to macroscopic cracks.

The cracking process is usually slow and takes several cycles before the crack propagates to the extent that the material fails catastrophically. The factors that influence the fatigue failure of materials include cyclic load, mean stress, surface finish, temperature, and corrosive media. The cyclic loading conditions include amplitude, frequency, and waveform of the load. The mean stress is the average stress during one cycle.

The surface finish of the material plays a crucial role in the initiation and propagation of the crack. The higher the surface roughness, the more likely it is that a crack will initiate at that location. The temperature and corrosive media affect the fatigue failure of the material by promoting chemical reactions that can accelerate the cracking process.

The angle of twist at the end A is approximately 0.02035 radians.

To calculate the angle of twist at the end A of a tapered shaft, we use the formula:

θ = ∫(T/(GJ))dx

Where θ is the angle of twist, T is the applied torque, G is the shear modulus of elasticity, and J is the polar moment of inertia, which for a circular cross-section is J = (π/2)r^4.

The given function for the radius r is r = 0.02(1 + x^3/2). Substituting this into the equation for J and integrating with respect to x from 0 to L (the length of the shaft) gives:

θ = ∫(T/(G(π/2)(0.02(1 + x^3/2))^4))dx

= ∫(T/(G(π/2)(0.02)^4(1 + x^3/2)^4))dx

= 16T/(G(π)(0.02)^4) ∫(1/(1 + x^3/2)^4)dx

Substitute the given values: T = 440 N⋅m, G = 27 GPa = 27 * 10^9 Pa.

Answer:

To calculate the convolution of x(t) and h(t), we need to use the following formula:

y(t) = integral from 0 to t of {x(tau) h(t - tau) d(tau)}

First, we need to find x(tau) and h(t - tau):

x(tau) = u(tau - 3) - u(tau - 5)

h(t - tau) = e^(-3(t - tau)) u(t - tau)

Substituting these into the convolution formula, we get:

y(t) = integral from 0 to t of {(u(tau - 3) - u(tau - 5)) e^[-3(t - tau)] u(t - tau) d(tau)}

Since u(tau - 3) and u(tau - 5) are step functions, they are non-zero only when tau >= 3 and tau >= 5, respectively. Therefore, the integral can be broken up into two parts:

y(t) = integral from 3 to t of {(u(tau - 3) - u(tau - 5)) e^[-3(t - tau)] d(tau)}

- integral from 5 to t of {(u(tau - 5)) e^[-3(t - tau)] d(tau)}

Simplifying this, we get:

y(t) = (e^(-3t)) [integral from 3 to t of e^(3tau) d(tau) - integral from 5 to t of e^(3tau) d(tau)]

- e^(-15t) integral from 5 to t of e^(3tau) d(tau)

Evaluating the integrals, we get:

y(t) = (1/3) e^(-3t) [e^(3t) - e^(9)] u(t - 3) - (1/3) e^(-3t) [e^(3t) - e^(15)] u(t - 5)

Therefore, the convolution of x(t) and h(t) is:

y(t) = (1/3) e^(-3t) [e^(3t) - e^(9)] u(t - 3) - (1/3) e^(-3t) [e^(3t) - e^(15)] u(t - 5)

Truss bridges are made up of interconnected triangles that distribute weight evenly across the structure, making them highly resistant to bending and compression forces. They are also relatively easy to construct using simple materials such as wood or steel, which may make them a more practical option for underserved communities.

That being said, arch bridges can also be quite strong and durable, as they rely on the inherent strength of their curved shape to distribute weight. Suspension and cable-stayed bridges, on the other hand, require more advanced engineering and construction techniques, and may be less feasible for communities with limited resources. Beam bridges are typically the simplest type of bridge, but may not be as strong or versatile as truss or arch bridges.

When a bob attached to a string of length L moves in a horizontal circle while the string maintains an angle θ from the vertical, the tangential speed v required can be determined by analyzing the forces acting on the bob.

The force of tension in the string provides the centripetal force required to keep the bob moving in a circle. Using the formula for centripetal force, mv^2/L = T = mg cos θ, where m is the mass of the bob, g is the acceleration due to gravity, and 0 is the initial angle from the vertical, we can solve for v to get:

v = (L cos θ) * √(g / (L - L cos θ))

This formula shows that the tangential speed required for the bob to move in a horizontal circle is directly proportional to the cosine of the angle θ and the square root of the acceleration due to gravity g, while inversely proportional to the difference between the length of the string L and the cosine of the angle θ.

The address of the element stored at arr[20][30] in the 2-D array declaration char Arr[100][100] would be 30 + 20 * 100 = 2030.

The declaration of the 2-D array is shown below:

char Arr[100][100]

Here, Arr is a 2-D array consisting of 100 rows and 100 columns. This means that there are a total of 10,000 elements in this array. Each element of this array is of type char. Therefore, each element will occupy a single byte of memory.

The array is byte-addressable. This means that each element of the array is accessible using its byte address. Since each element occupies a single byte of memory, the byte address of an element is the same as its memory address.

To calculate the address of the element stored at arr[20][30], we first need to understand how the elements are stored in the array.

The elements of a 2-D array are stored in row-major order. This means that the elements of the first row are stored first, followed by the elements of the second row, and so on. Within a row, the elements are stored from left to right.Now, to calculate the address of the element stored at arr[20][30], we need to calculate the byte address of this element. Since the array is byte-addressable, we can calculate the byte address of an element by multiplying its row number by the number of columns in the array and adding its column number. This gives us the following formula:

Byte Address of Element = Base Address + (Row Number * Number of Columns + Column Number)

Since the base address of the array is 0, we can simplify this formula to:

Byte Address of Element = Row Number * Number of Columns + Column Number

Using this formula, we can calculate the byte address of the element stored at arr[20][30] as follows:

Byte Address of Element = 20 * 100 + 30 = 2030

Therefore, the address of the element stored at arr[20][30] is 2030.
