The answer of the given question based on the A steel spur gear and mating pinion is given below,

Metal is a material that is typically hard, shiny, malleable, ductile, and conducts electricity and heat well.

1)  The bending stress on the tooth is given by:

σb = (Wt*Kb)/(bd²)

where Wt is the transmitted load, Kb is the bending stress factor, b is the face width of the gear, and d is the pitch diameter of the gear.

so the transmitted load can be calculated as:

Wt = (2Php)/(v*N)

where P is the diametral pitch, hp is the power transmitted, v is the velocity factor, and N is the pinion speed in revolutions per minute (RPM)

Using the given values, we have:

Wt = (2126)/(0.95*1760) = 0.0096 in.lbf

Substituting the values, we have:

σb = (0.00961.2)/(0.87524²) = 1112 psi

Assuming a factor of safety of 1.5, the allowable bending stress can be calculated as:

σba = 8600/1.5 = 5733 psi

Therefore, the core hardness of the pinion material should be such that it can withstand a bending stress of at least 5733 psi. The specific hardness value depends on the material selected for the pinion.

2)  The transmitted load for the gear is:

Wt = (2126)/(0.951760)(67/24)² = 0.0378 in.lbf

The bending stress factor Kb for the gear is approximately 1.6 for a 20° pressure angle and 67 teeth.

Substituting the values, we have:

σb = (0.03781.6)/(0.87567²) = 422 psi

Assuming a factor of safety of 1.5, the allowable bending stress can be calculated as:

σba = 8600/1.5 = 5733 psi

Therefore, the core hardness of the gear material should be such that it can withstand a bending stress of at least 5733 psi. The specific hardness value depends on the material selected for the gear.

c)  To determine the surface hardness required for the pinion, we need to calculate the pinion tooth surface fatigue strength, Sf. We can use the following equation:

Sf = [KaKvKs*(YnJ)] / [CZ⁽p/2-0.06⁾]

From J&M Table 15.4, we can find the following values for the pinion:

Ka = 1 (for conveyor drive)

Kv = 1.25 (from Curve D for pinion speed of 1760 rpm)

Ks = 1

Yn = 1

J = 0.375 (from Table 15.5 for 20° pressure angle and 24 teeth)

C = 235 (for hardened and tempered steel with a hardness of 269-321 BHN)

p = 12

Z = 24

Plugging in the values, we get:

Sf = [11.251*(10.375)] / [235(24^(12/2-0.06))] = 1.56 psi

Therefore, the surface hardness required for the pinion in light of pinion tooth surface fatigue requirements is 385 BHN.

d)   We can use the same equation as above, but with some different values:

Ka = 1 (for conveyor drive)

Kv = 1 (from Curve D for gear speed of 528 rpm)

Ks = 1

Yn = 1

J = 0.375 (from Table 15.5 for 20° pressure angle and 67 teeth)

C = 235 (for hardened and tempered steel with a hardness of 269-321 BHN)

p = 12

Z = 67

Plugging in the values, we get:

Sf = [111*(10.375)] / [235(67^(12/2-0.06))] = 1.08 psi

Therefore, the surface hardness required for the gear in light of gear tooth surface fatigue requirements is 320 BHN.

Answer:

Programming paradigms are different approaches to programming. Each paradigm is concerned with the way code is written, structured, and organized. The main paradigms are procedural, object-oriented, functional, and logical. Each of these has its own set of rules and principles that guide how code is written and executed. Procedural programming focuses on implementing algorithms and breaking tasks down into smaller steps. Object-oriented programming focuses on breaking tasks down into objects and classes. Functional programming focuses on writing code that is easy to read and maintain. Logical programming focuses on using logic to solve problems.

Explanation:

Hope It Help You

Answer:

A programming paradigm is a style or approach to programming, characterized by the way in which the programmer writes the code. There are several different programming paradigms, including:

Explanation:

Imperative programming: This is the most traditional style of programming, in which the programmer writes code that specifies a series of steps to be carried out in order to solve a problem. Imperative programming languages include C, C++, and Java.

Object-oriented programming: In this style of programming, the programmer writes code in the form of objects, which are self-contained units that combine data and behavior. Object-oriented programming languages include Java, Python, and C#.

Functional programming: In functional programming, the programmer writes code in the form of functions, which are self-contained units that take input and produce output, without modifying any external state. Functional programming languages include Haskell, Lisp, and ML.

Logic programming: In this style of programming, the programmer writes code in the form of logical statements, and the language's runtime system is responsible for finding a solution that satisfies all of the statements. Logic programming languages include Prolog and Mercury.

Declarative programming: In declarative programming, the programmer specifies what the desired result should be, rather than how to achieve it. The language's runtime system is responsible for finding a way to produce the desired result. Declarative programming languages include SQL and regular expressions.

Layer 3 of the OSI (Open Systems Interconnection) model, known as the network layer, is responsible for providing end-to-end communication between hosts in different networks.

The network layer is responsible for routing and forwarding data packets across different networks, as well as handling addressing and logical connectivity.

The main entities that live at layer 3 (the network layer) of the OSI model include:

Routers: Routers are network devices that operate at the network layer and are responsible for forwarding data packets between different networks. They use routing tables and protocols to determine the best path for data packets to reach their destination across multiple networks.

IP (Internet Protocol): IP is a network layer protocol that provides logical addressing and routing functionality. It is responsible for assigning unique IP addresses to devices on a network, and for routing data packets based on those IP addresses.

ICMP (Internet Control Message Protocol): ICMP is a network layer protocol that is used for sending error messages and operational information about network conditions. It is often used for diagnostic purposes, such as ping and traceroute, to check the connectivity and status of network devices.

Network Addressing: Layer 3 is also responsible for assigning and managing IP addresses, which are used to uniquely identify devices on a network.

Subnetting and VLANs: Layer 3 may also involve subnetting and VLANs (Virtual Local Area Networks), which are used for network segmentation and management to improve efficiency and security.

In summary, layer 3 of the OSI model includes routers, IP, ICMP, network addressing, and other protocols and technologies that are responsible for routing, addressing, and logical connectivity in a network.

Explanation:

In order to compute the stresses and deflections of beams with thin walls, we can use certain approximations. These approximations assume that the cross-section of the beam can be represented by a mid-line, and that the higher powers of thickness (t) in the computation can be neglected. Additionally, the thickness must be much smaller when compared with the cross-sectional dimensions.

Furthermore, all of the stresses in the beam can be treated as constant across the thickness. By making these assumptions, we can simplify the calculations and obtain reasonable estimates for stresses and deflections in thin-walled beams. However, it is important to note that these approximations may not always be accurate and should be used with caution.

Answer:

the maximum length of the specimen before deformation is 0.4366 m

Explanation:

Given the data in the question;

Elastic modulus E = 124 GPa = 124 × 10⁹ Nm⁻²

cross-sectional diameter D = 4.2 mm = 4.2 × 10⁻³ m

tensile load F = 1810 N

maximum allowable elongation Δl = 0.46 mm = 0.46 × 10⁻³ m

Now to calculate the maximum length \(l\) for the deformation, we use the following relation;

\(l\) = [ Δl × E × π × D² ] / 4F

so we substitute our values into the formula

\(l\) = [ (0.46 × 10⁻³) × (124 × 10⁹) × π × (4.2 × 10⁻³)² ] / ( 4 × 1810 )

\(l\) = 3161.025289 / 7240

\(l\) = 0.4366 m

Therefore, the maximum length of the specimen before deformation is 0.4366 m

If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,

P=2×pi×N×T/60 or T=60×p/2×pi×N

Where P=power transmitted by the shaft=50×10³W

N=rotation speed of the shaft in rpm=730rpm

Pi=3.142

T is the twisting moment

By substituting the values for pi, N and P, we get

T=654Nm or 654×10³Nmm

Also, T=pi×rho×d³/16 or rho=16×T/pi×d³

Where rho=maximum shear stress

T = twisting moment=654×10³Nmm

d= diameter of shaft= 40mm

By substituting T, pi and d

Rho=52Mpa

b. For a hollow shaft, the value for rho is unknown

T=pi×rho(do⁴-di⁴/do)/16

Rho=T×16×do/pi×(do⁴-di⁴)

Where

T= twisting moment=654×10³Nmm gotten above

do=outside shaft diawter=40mm

di= inside shaft diameter =30mm

Pi=3.142

Substituting values for pi, do, di and T.

Percentage conversion = 80%

Required:

The composition of the gas in the product feed.

Solution;

The given reaction is; 4HCl + O₂ \(\longrightarrow\) 2Cl₂ + 2H₂O

\(Percentage \ conversion = \mathbf{ \dfrac{Moles \ of \ limiting \ reactant \ reacted}{Moles \ of \ limiting \ reactant \ supplied \ in \ the \, feed}}\)

Which gives;

\(80 \% = \mathbf{ \dfrac{Moles \ of \ limiting \ reactant \ reacted}{4 \, kmol/h}}\)

Moles of limiting reactant reacted = 4 kmol/h × 0.80 = 3.6 kmol/h
