Sketch a stone bridge, a steel bridge, a wood bridge, and a reinforced concrete bridge. Describe how their shape is related to the properties of the material.
Answers
The shape of a bridge is determined by the material it's made of. Bridges are made from different materials such as wood, steel, stone, and reinforced concrete.
Stone bridge: A stone bridge is built from stone blocks or stones that are cut and fitted together. The shape of a stone bridge is typically arched or curved. This is because stone is a very heavy and dense material that can withstand a lot of pressure. The arched shape of the stone bridge helps distribute the weight of the bridge evenly across the supporting pillars.
Steel bridge: A steel bridge is made from steel beams or trusses. The shape of a steel bridge is typically angular and geometric. This is because steel is a very strong material that can be easily molded and shaped into different shapes. The angular shape of the steel bridge helps distribute the weight of the bridge evenly across the supporting pillars. The shape also helps provide stability and prevent the bridge from swaying or moving in high winds.

in an aligned and continuous carbon fiber-reinforced nylon 6,6 composite, the fibers are to carry 97% of a load applied in the longitudinal direction. using the data provided, determine the volume fraction of the fibers that will be required. what will be the tensile strength of this composite? assume that the matrix stress at which fiber failure is 50 mpa
Answers
tensile strength of this composite will be 9.6 MPa.
To determine the volume fraction of the fibers, we need to use the rule of mixtures which states that the overall properties of a composite material are a weighted average of the properties of the individual components.
In this case, we can use the equation:
Vf = (Fload / Ffiber) / (Fload / Ffiber + Fload / Fmatrix)
where Vf is the volume fraction of the fibers, Fload is the load applied in the longitudinal direction, Ffiber is the strength of the fibers in the longitudinal direction, and Fmatrix is the stress at which fiber failure occurs in the matrix.
Plugging in the values given:
Vf = (0.97 / 1) / (0.97 / 1 + 0.03 / 50)
Vf = 0.841
Therefore, the volume fraction of the fibers that will be required is 84.1%.
To find the tensile strength of the composite, we need to use the equation:
Fcomposite = Vf * Ffiber + (1 - Vf) * Fmatrix
where Fcomposite is the strength of the composite, Vf is the volume fraction of the fibers, Ffiber is the strength of the fibers in the longitudinal direction, and Fmatrix is the stress at which fiber failure occurs in the matrix.
Plugging in the values given:
Fcomposite = 0.841 * 1 + (1 - 0.841) * 50
Fcomposite = 9.6 MPa

Optimal control is a design approach which is extensively used in many applications including aerospace. In particular, it is considered to be a very practical design approach.
Recall the main features of optimal control design and explain why it can be considered to be quite practical in comparison to direct pole placement design.
Answers
Optimal control is a technique for designing a control system that maximizes some performance criterion, typically defined as a weighted sum of the control effort and the system's output. This design approach is widely used in aerospace, among other fields, and it is considered to be a very practical design approach.
There are several reasons why optimal control design can be considered practical in comparison to direct pole placement design. One of the main features of optimal control design is that it can handle systems with multiple inputs and outputs, which is a common requirement in aerospace applications. In contrast, direct pole placement design is typically limited to single-input, single-output systems.
Another advantage of optimal control design is that it can handle nonlinear systems, which are common in aerospace applications. Nonlinear systems are typically more difficult to control than linear systems, and direct pole placement design may not be effective for these types of systems.Optimal control design also provides a systematic way to trade off between competing design objectives, such as tracking performance and control effort.
This is important in aerospace applications, where minimizing fuel consumption and maximizing performance are often competing objectives.In conclusion, optimal control design is a practical design approach for aerospace applications because it can handle systems with multiple inputs and outputs, nonlinear systems, and competing design objectives.

Problem 2 Six years ago, an 80-kW diesel-electric set cost $145,000. The cost index for this class of equipment six years ago was 187 and is now 194. The plant engineering staff was considering a 120−kW unit of the same general design to power a small isolated plant that would have cost $200,145. Based on the information above the plant engineering staff is considering a 100−kW unit of the same general design to power a small isolated plant. Assume we want to add a pre-compressor, which (when isolated and estimated separately) currently costs $10,000. Determine the total cost of the 100−kW unit.
Answers
The total cost of the 100−kW unit= Cost of 100−kW unit + Additional cost of the pre-compressor= $166,786 + $10,000= $176,786.
Given: Cost of 80-kW diesel-electric set six years ago = $145,000Cost index for this class of equipment six years ago = 187Cost index for this class of equipment now = 194Cost of 120−kW unit of the same general design to power a small isolated plant = $200,145
The plant engineering staff is considering a 100−kW unit of the same general design to power a small isolated plant.Cost of adding pre-compressor = $10,000
To determine the total cost of the 100−kW unit, we need to find the cost of the 80-kW diesel-electric set at present, the cost of the 100−kW unit, and the additional cost of the pre-compressor.Cost of 80-kW diesel-electric set at present= Cost of 80-kW diesel-electric set six years ago × (Cost index for this class of equipment now / Cost index for this class of equipment six years ago)= $145,000 × (194 / 187)= $150,816.34Cost per kW of the 80-kW diesel-electric set= Cost of 80-kW diesel-electric set at present / 80= $150,816.34 / 80= $1,885.20
Cost per kW of the 120−kW unit= Cost of 120−kW unit / 120= $200,145 / 120= $1,667.87The cost of the 100−kW unit of the same general design= 100 × Cost per kW of the 120−kW unit= 100 × $1,667.87= $166,786
Additional cost of the pre-compressor= $10,000. Hence, the total cost of the 100−kW unit is $176,786.

None of the above options accurately explain why bicycles are imperfect substitutes for planes.
Bicycles and planes are considered imperfect substitutes for various reasons. The choice between a bicycle and a plane for long distances is influenced by factors such as speed, convenience, comfort, and the availability of infrastructure. While some individuals may choose bicycles due to personal preferences or environmental concerns, the majority of people would not choose a bicycle over a plane for long-distance travel. Bicycles have limited speed and endurance, are impractical for crossing large bodies of water or international distances, and may not be suitable for individuals with physical limitations. Additionally, planes offer significant time savings and can cover vast distances efficiently.

Knowing that the central portion of the link BD has a uniform cross-sectional area of 800 2, determine the magnitude of the load P for which the normal stress in that portion of BD is 50 .
Answers
Answer: 50
Explanation:
A horizontal curve on a two-lane highway (12-ft lanes) has PC at station 123+80 and PT at station 129+60. The central angle is 35 degrees, the superelevation is 0.08, and 20.6 ft is cleared (for sight distance) from the inside edge of the innermost lane. Determine a maximum safe speed (assuming current design standards) to the nearest 5 mi/hr.
Answers
First, let's calculate the radius of curvature of the curve:
Central angle = 35 degrees
Length of curve = PT - PC = (129+60) - (123+80) = 5+80 = 580 ft
Radius of curvature = (360 / (2 * pi)) * (Length of curve / Central angle) = (360 / (2 * 3.1416)) * (580 / 35) = 331.77 ft
Next, let's calculate the design speed of the curve using the AASHTO (American Association of State Highway and Transportation Officials) design speed formula:
Design speed = ( (Radius of curvature * Superelevation) / (Clearance + 1/2 Lane width) )^0.5 * (M / f)^0.15
where M is the coefficient of friction between the tires and the roadway surface, and f is the side friction factor, which depends on factors such as the curvature of the roadway, superelevation, and surface condition.
Assuming a conservative value of M = 0.4 and f = 0.15, and plugging in the given values, we get:
Design speed = ( (331.77 * 0.08) / (20.6 + 6) )^0.5 * (0.4 / 0.15)^0.15
= 39.67 mph
However, we need to round down to the nearest 5 mph to ensure a margin of safety, so the maximum safe speed is 35 mph.

Answers
This problem can be solved using the pascal principle, which is applied for both pressures and volumes. In this case we use the definition of volumes, which says that the volume displaced fluid on one side of the Pistons should be equal to the volume displaced on the other side of the piston.
What is force?The force exerted at the large piston will be double in magnitude in comparison with the force applied at the smaller piston.
We know, according to the pascal's law,
The pressure applied at any point in the incompressible fluid is equal in magnitude at each and every point.
So,
P = Force/Area
Where P is pressure,
If pressure is same, then we can write,
F₁/A₁ = F₂/A₂
Where,
F₁ is the force applied at the small piston,
A₁ is the area of the smaller piston,
F₂ is the force at the larger piston,
A₂ is the area of the larger piston,
It is also given that, area if the larger piston is two times the area of the smaller piston so,
A₂ = 2A₁
So, putting the values we get,
F₂/F₁ = 2
So, F₂ = 2F₁
It means that the force exerted by the larger piston will be double in magnitude.
Therefore, In this case we use the definition of volumes, which says that the volume displaced fluid on one side of the Pistons should be equal to the volume displaced on the other side of the piston.
