1. The width of the lens 0.5 centimeters from the vertex is 6 centimeters.

1. To find the width of the lens 0.5 centimeters from the vertex, we can use the property of a parabolic lens that states the distance from the vertex to the focal point is equal to half the width of the lens.

Given:

Distance from vertex to focal point (f) = 3 centimeters

Let's denote the width of the lens as "w". According to the property mentioned above, we can write the equation as:

f = w/2

Substituting the given value of f, we have:

3 = w/2

To find the width of the lens, we can solve the equation for "w":

w = 3 * 2 = 6 centimeters

Therefore, the width of the lens 0.5 centimeters from the vertex is 6 centimeters.

2. To find the equation of the hyperbola with the given information, we need to determine the coordinates of the vertices and the distance between the foci.

Given:

Distance between the vertices (2a) = 2 feet

Distance between the foci (2c) = 0.5 feet

The distance between the center of the hyperbola and each focus is given by the relation: c^2 = a^2 + b^2, where "a" is the distance from the center to each vertex, and "c" is the distance from the center to each focus.

Since we are given 2a = 2 feet and 2c = 0.5 feet, we can solve for "a" and "c" as follows:

2a = 2

a = 1 foot

2c = 0.5

c = 0.25 feet

Now, we can write the equation of the hyperbola in standard form:

(x^2 / a^2) - (y^2 / b^2) = 1

Substituting the values of "a" and "c", we have:

(x^2 / 1^2) - (y^2 / b^2) = 1

(x^2) - (y^2 / b^2) = 1

The equation of the hyperbola is (x^2) - (y^2 / b^2) = 1. The specific value of "b" is not given in the provided information, so we cannot determine the exact equation of the hyperbola without additional information.

To determine the horizontal and vertical components of reaction at point A and the reaction at point B on the beam, we can use the principles of static equilibrium.

Let's break down the problem step by step:

1. Draw a free body diagram of the beam. Label the known forces and reaction components.

2. Since the beam is supported by a pin at point A, the reaction at point A will only have a vertical component (RAy) and no horizontal component (RAx).

3. The strut BC exerts a force on the beam at point B. This force can be broken down into horizontal (FBx) and vertical (FBy) components.

4. Apply the equations of equilibrium. The sum of all the horizontal forces acting on the beam should be equal to zero, and the sum of all the vertical forces acting on the beam should also be equal to zero.

5. Set up the equations:

Sum of horizontal forces: FBx - RAx = 0
Sum of vertical forces: RAy + FBy = 0

6. Substitute the known values and solve the equations to find the unknowns. The value of RAx will be zero since there is no horizontal component at point A.

The equations of the elastic curve can be determined using the coordinate values x1 and x2, assuming that EI is constant. Establish the differential equation of the elastic curve, which is EI(d^2y/dx^2) = M(x), where M(x) is the bending moment, and EI is the flexural rigidity.

The elastic curve is the shape that a beam or other structural member takes on when subjected to bending loads. To determine the equations of this curve, we need to use the formula for the deflection of a beam under load. This formula is derived from the Euler-Bernoulli beam theory, which relates the bending moment, shear force, and deflection of a beam to its stiffness and geometry.

In practical terms, the equations of the elastic curve are used to design and analyze structural members such as beams, columns, and trusses. By knowing the shape of the elastic curve, we can calculate the stresses and strains in the member, which in turn can be used to determine its strength and deformation characteristics. This information is critical for ensuring the safety and performance of structures under different loading conditions.

The work done on the gas during this process if the final pressure is 456 kPa is; -82.8 kJ

We are given;

The initial pressure; P₁ = 96 kPa

Final Pressure; P₂ = 456 kPa

The gas is compressed according to;

p = aV + b

where;

a = -1200 kPa/m³

b = 600 kPa

Thus, at initial pressure P₁ = 96 kPa;

96 = -1200V₁ + 600

1200V₁ = 600 - 95

1200V₁ = 505

V₁ = 505/1200

V₁ = 0.42 m³

At Final Pressure P₂ = 456 kPa;

456 = -1200V₂ + 600

1200V₂ = 600 - 456

1200V₂ = 144

V₂ = 144/1200

V₂ = 0.12 m³

Formula for the workdone during the process is;

W_out = ¹/₂(P₁ + P₂)(V₂ - V₁)

Answer:

Explanation:

The summation of the forces in vertical direction

= Fb - Fd - w = 0 ∴ Fd = Fb - w  ----- ( 1 )

Fb ( buoyant force ) = Pair * g * Vballoon ------- ( 2 )

Pair = air density , Vballoon = volume of balloon

Vballoon = \(\frac{\pi D^3}{6}\) ,  where D = 4  ∴  Vballoon = 33.51 ft^3

g = 32.2 ft/s^2

From property tables

Pair = 2.33 * 10^-3 slug/ft^3

μ ( dynamic viscosity ) = 3.8 * 10^-7 slug/ft.s

Insert values into equation 2

Fb = ( 2.33 * 10^-3 ) * ( 32.2 ) *( 33.51 )  = 2.514 Ib

∴ Fd = 2.514 - 2.5 = 0.014 Ib ( equation 1 )

Assuming that flow is Laminar  and  RE < 1

Re = (Pair * vd) / μair   -------- ( 3 )

where:  Pair = 2.33 * 10^-3 slug/ft^3 ,  vd = ( 987 * 4 ) ft^2/s ,   μair = 3.8 * 10^-7 slug/ft.s

Insert values into equation 3

Re = 2.4 * 10^7 (  this means that the assumption above is wrong )

Hence we will use drag force law

Assume Cd = 0.5

Express  Fd using the relation below

Fd = 1/2* Cd * Pair * AV^2

therefore V = 1.39 ft/s

Recalculate  Reynold's number using  v = 1.39 ft/s

Re = 34091

from the figure Cd ≈ 0.5 at Re = 34091  

Finally calculate the rise time ( time taken to reach an altitude of 1000 ft )

t = h/v

  = 1000 / 1.39 = 719 seconds ≈ 12 mins

Explanation:

diameter d of rod = 4 mm

radius r of the rod = d/2 = 4/2 =0.002 m

length L of rod = 100 mm = 0.1 m

temperature of rod = 455 °C

temperature in kelvin = 455 + 273.3 = 728.3 K

emissivity ε of rod = 0.5

external radiative surface area of rod is calculated as

A = \(\pi r^{2} L\) = 3.142 x \(0.002^{2}\) x 0.1 = 1.26 x \(10^{-6}\) m^2

Power dissipiation P = εσA(\(T^{4}\))

where σ Stefan's constant = 5.67 x \(10^{-8}\) W-\(m^{2}\)-\(K^{4}\)

P = 0.5 x 5.67 x \(10^{-8}\) x  1.26 x \(10^{-6}\) x \(728.3^{4}\) = 0.01 W

Concrete pavement is often unreinforced, depending on the type of concrete used, the base it is placed on, and design considerations specific to the project. Flexible concrete actually performs better without reinforcing bars except at stress locations such as angled segments and sharp curves. Because the design mix allows the hardened, cured concrete to flex before it cracks/breaks, rebar would actually contribute to cracking if it flexes.

Where reinforcing is critical is in bridging, that is, where a section isn’t on solid base material. When placed on structural base where a sufficient CPR or LBR (California Bearing Ration or Limestone Bearing Ratio) is achieved, the base is a material that is compacted and stiff/hard enough to support the full weight of the concrete plus the designed load of traffic. In locations where soft material isn’t or cannot be mitigated by overexcavating and filling with stronger material for subgrade and base, reinforcing bars are needed.

One thing to note is that even though the slab may not need to be reinforced, joints are usually dowelled with steel bars so that slabs remain flush if settling does occur. These are often 3/4 inch or one inch steel bars that are slipped through the formwork so that half is in one slab, and half in the adjacent. One ends is sometimes greased to allow the dowel to slide when the slabs expand and contract.

Other methods are used in highway pavement, such as steel fiber reinforcement, polyester fiber reinforcement, and others, that are blended into the concrete when it is mixed.

Still other techniques are used to mitigate cracks caused by expansion/shrinkage in pavement slabs, like entraining air, using shrinkage reducing admixtures, controlling slump during placing, and curing with membranes to slow dehydration after the concrete is placed. This answer is applicable to the region where I work, in the southeast U.S., and probably different climates have different needs, particularly very cold climates, or places where stable ground conditions are difficult to achieve.

Its not essential. . . but it can be used to assist in crack control.

For the AND column, a 1 is being output only when all three inputs are 1. Otherwise, a 0 results.

For the NAND column (which is the negation of the AND), a 0 is being output only when all three inputs are 0. Otherwise, a 1 results.

For the OR column, a 1 is being output when at least one of the three inputs is 1. Otherwise, a 0 results.

For the NOR column (which is the negation of the OR), a 0 is being output when at least one of the three inputs is 0. Otherwise, a 1 results.

For the XOR column, a 1 is being output when the number of inputs that are true (1) is odd. i.e when the number of 1s is 1 or 3. Otherwise, a 0 results.

For the XNOR column (which is the negation of the XOR), a 0 is being output when the number of inputs that are true (1) is odd. i.e when the number of 1s is 1 or 3. Otherwise, a 1 results.

Under cold air standard conditions, the thermal efficiency of this cycle is 56.9 percent.

Explanation:

From Thermodynamics we remember that thermal efficiency of the ideal Otto cycle (\(\eta_{th}\)), dimensionless, is defined by the following formula:

\(\eta_{th} = 1-\frac{1}{r^{\gamma-1}}\) (Eq. 1)

Where:

\(r\) - Compression ratio, dimensionless.

\(\gamma\) - Specific heat ratio, dimensionless.

Please notice that specific heat ratio under cold air standard conditions is \(\gamma = 1.4\).

If we know that \(r = 8.2\) and \(\gamma = 1.4\), then thermal efficiency of the ideal Otto cycle is:

\(\eta_{th} = 1-\frac{1}{8.2^{1.4-1}}\)

\(\eta_{th} = 0.569\)

Under cold air standard conditions, the thermal efficiency of this cycle is 56.9 percent.
