The force required to move a fluid is proportional to the shear stress on the surface of the plate. The shear stress is defined as the force per unit area acting perpendicular to the surface. For a Newtonian fluid, the shear stress is proportional to the velocity gradient.

In this problem, the velocity profile is given as u = (6y - 0.4y^2) mm/s, where y is the height from the plate. The velocity gradient can be calculated as du/dy = 6 - 0.8y mm/s^2. The shear stress is then given by τ = μ * du/dy, where μ is the dynamic viscosity.

The total force required to move the fluid is given by the product of the shear stress and the surface area of the plate. Since the surface area of the plate is 20,000 mm^2, the force P can be calculated as P = 20,000 * μ * (du/dy). Integrating the velocity gradient over the entire height of the fluid, we get the total force required to move the fluid as:

P = 20,000 * μ * (6y - 0.4y^2)

By substituting the values given in the problem, we get:

P = 20,000 * 0.482 * (6y - 0.4y^2) N

This is the force that must be applied to the plate to cause the motion defined by the velocity profile.

If we have a sorted array [0,−1]. the number of comparisons to search for the existence of an element in the given array using binary search would be 2 comparisons.

Binary search is a search algorithm that works by dividing the input array into two halves at each step and comparing the target element with the middle element of the array.

In this case, the array [0, -1] has two elements and is already sorted. To search for the existence of an element in this array using binary search, the algorithm would perform the following steps:

Initialize the start and end indices to the first and last elements of the array, respectively.

Calculate the middle index as the average of the start and end indices.

Compare the target element with the element at the middle index.

If the target is equal to the element at the middle index, the search is successful and ends.

If the target is greater than the element at the middle index, set the start index to the middle index + 1, and repeat steps 2 to 4.

If the target is less than the element at the middle index, set the end index to the middle index - 1, and repeat steps 2 to 4.

In this case, the target element can be either 0 or -1, and both searches would take 2 comparisons to determine its existence in the array.

To determine the resultant internal loads acting on a cross-section through points F and G of the frame, we need to consider the normal force (N), shear force (V), and bending moment (M) acting on the section.

For the first case, N = 75.0 lb, V = 355 lb, M = -727 lb.ft, the bending moment is negative, which indicates that the section is subjected to a clockwise bending moment. The normal force is positive, which indicates that the section is subjected to an upward normal force. The shear force is positive, which indicates that the section is subjected to a rightward shear force. These loads can be calculated based on the structural analysis of the frame and the external loads applied to the frame.

For the second case, N = 355 lb, V = 75.0 lb, M = -727 lb.ft, the bending moment is negative, which indicates that the section is subjected to a clockwise bending moment. The normal force is positive, which indicates that the section is subjected to an upward normal force. The shear force is positive, which indicates that the section is subjected to a leftward shear force.

For the third case, N = 130 lb, V = 355 lb, M = -727 lb.ft, the bending moment is negative, which indicates that the section is subjected to a clockwise bending moment. The normal force is positive, which indicates that the section is subjected to an upward normal force. The shear force is positive, which indicates that the section is subjected to a rightward shear force.

For the fourth case, N = 75.0 lb, V = 355 lb, M = 727 lb.ft, the bending moment is positive, which indicates that the section is subjected to a counterclockwise bending moment. The normal force is positive, which indicates that the section is subjected to an upward normal force. The shear force is positive, which indicates that the section is subjected to a rightward shear force.

To determine the resultant internal loads acting on the cross-section through Point E of the given structure, we can use the same procedure and consider the normal force (N), shear force (V), and bending moment (M) acting on the section. We can calculate these loads based on the structural analysis of the frame and the external loads applied to the frame. The sign convention used to determine the direction of the loads is the same as described above.

In conclusion, to determine the resultant internal loads acting on a cross-section of a frame, we need to consider the normal force (N), shear force (V), and bending moment (M) acting on the section and use the appropriate sign convention to determine the direction of the loads.

eD = D/q∞e²                  equation 2

Fr = V/√gc                     equation 3

Equation 1 can be expressed as  f(p∞, V∞, c, g) = 0

Number of physical parameters(n) = 5

Number of fundamental dimensions(k) = 3

According to Buckingham π theorem, this equation can be a function of (n-k = 2) dimensionless period (π1 and π2)

Let

π1 = f(p∞, V∞, c, g)

π2 = f(p∞, V∞, c, D)

We can further express the π1 terms as follows:

π1 = p∞ a1 × V∞b1 × [tex]c^{c}[/tex] × g

Substituting units:

π1 = [[tex]ML^{-3}[/tex]]a1 × [[tex]LT^{-1}[/tex]]b1 × [L]c × g

a1 = 0,

b1 + c1 + 1 = 0,

-b1 - 2 = 0

a1 = 0, b1 = -2, c1 = 1

So,

π1  = V∞ -2 × c × g

Now,

We can further express the π2 terms as follows:

π2 = p∞ a1 × V∞b1 × [tex]c^{c}[/tex] × g

Substituting units:

π2 = [[tex]ML^{-3}[/tex]]a1 × [[tex]LT^{-1}[/tex]]b1 × [L]c × g

a2 + 1 = 0,

-b2 - 2 = 0,

-3a2 + b2 + c2 + 1 = 0

a2 = -1, b2 = -2, c2 = -2

So,

π1  =D/ p∞ × V∞ × c

We reached that,

f(π1, π2) = f(c × g/V∞2 , D/p∞ × V∞ × c ) = 0

To move a piston (or several pistons) back and forth, steam engines require hot steam produced by boiling water. Then a machine or wheel was powered by the piston's action.

The energy source for many machines and vehicles was steam power, which made it less expensive and simpler to create goods in huge quantities. As a result, there was a surge in the need for raw resources to make more machinery that could manufacture more goods. Thomas Savery introduced steam power to industry in 1698. He built and patent the first engine in London, which he named the "Miner's Friend" since it was designed to pump water from mines. Pressure was generated at high temperatures using steam power. This meant that the only energy source that was dependable and affordable enough to build equipment itself was steam power.

The exact value of factor of safety depend on the stress in a beam and it will generally be in the range of 2 to 3 for a conservative design.

The stress in a beam under pure bending is given by:

[tex]σ = My/I[/tex],

where M is the bending moment, y is the distance from the neutral axis, and I is the second moment of area of the cross-section.

The minimum design factor, N, is given by:

[tex]N = σ_allowable / σ,[/tex]

where [tex]σ_allowable[/tex] is the allowable stress, which includes the material strength and a factor of safety. The factor of safety accounts for the uncertainties in the loads, material properties, and manufacturing.

Given the uncertainties in M and a, the uncertainty in σ is given by:

[tex]Δσ = √((∂σ/∂M ΔM/M)^2 + (∂σ/∂a Δa/a)^2 + (Δf_s/f_s)^{2} )[/tex]

where [tex]Δf_s[/tex] is the uncertainty in the factor of safety, and [tex]f_s[/tex] is the factor of safety.

To determine the minimum design factor, we need to solve for the factor of safety, [tex]f_s[/tex], such that:

[tex]N = 1/√((∂σ/∂M ΔM/M)^2 + (∂σ/∂a Δa/a)^2 + (Δf_s/f_s)^2)[/tex]

Given that [tex]ΔM/M[/tex]= 0.08, [tex]Δa/a[/tex] = 0.09, and [tex]Δf_s/f_s[/tex] = 0.05, we can use a numerical method to find the minimum value of [tex]f_s[/tex] that satisfies the equation.

To  achieve a tension of 84 N in a 1.36 mm diameter string, it would require approximately 6,250 turns.

The number of turns required to achieve a tension in a string can be calculated using the formula:

T = k * d * N

where T is the tension in the string, k is the spring constant, d is the diameter of the string, and N is the number of turns.

To calculate k, we can use the formula:

k = G * A / L

where G is the modulus of elasticity of the material, A is the cross-sectional area of the string, and L is the length of the string.

Let's assume the modulus of elasticity for the material is 80 GPa and the length of the string is 1 m. Then, the cross-sectional area can be calculated as:

A = (pi/4) * d^2

Using the above formulas, we can calculate the spring constant:

k = 80 * (pi/4) * (1.36e-3)^2 / 1 = 0.68 N/turn

Finally, to find the number of turns required to achieve a tension of 84 N, we can use the formula:

N = T / (k * d) = 84 / (0.68 * 1.36e-3) = 6,250 turns
