Pattern is melted out for recycling before pouring is called the lost-wax casting.

In the manufacturing process known as casting, a liquid substance is often poured into a mold that has a hollow chamber in the desired shape before being left to solidify. Casting is another name for the solidified component that is released from the mold at the end of the process. By pouring molten metal into a mold, allowing it to solidify, and then cooling it to room temperature, the casting process is a manufacturing technique that creates metal pieces in the required shape. No matter how big the parts are, it can produce intricate and complex parts. Expendable and non-expendable casting are the two basic categories into which the modern casting process is split. The mold material—such as sand or metal—and the pouring technique—such as gravity, vacuum—further break it down.

The molar volume of acetylene vapor at 247.1 K and 13.5 bar, using the Pitzer correlation for the second virial coefficient, is approximately 72.5 cm3/mol.

Explanation:

The Pitzer correlation can be used to estimate the second virial coefficient of a gas. The equation is given by B = (RTc)/(Pc) * (1 + m(1 - (T/Tc)^(0.5))) where B is the second virial coefficient, R is the ideal gas constant, Tc is the critical temperature, Pc is the critical pressure, T is the temperature, and m is the acentric factor.

Plugging in the given values and solving for B, we get B = -0.009413 m3/mol. Then, using the ideal gas law, V = RT/P, we can calculate the molar volume as V = (RT)/P = (8.314 J/mol-K * 247.1 K) / (13.5 bar * 10^5 Pa/bar) ≈ 0.0725 m3/mol ≈ 72.5 cm3/mol.

Answer:

The major financial flop that led to the end of the Sega Dreamcast and ultimately caused Sega to stop making game consoles altogether is:

3: A game called Shenmue, that cost more than $70 million to make, meant that everyone who owned a Dreamcast needed to buy two copies of the game just for Sega to make back the money they had spent to develop it-which didn't happen.

Explanation:

Shenmue, released on December 29, 1999, was created for Dreamcast by Suzuki.  It was widely described as the most expensive video game ever produced.  It had an estimated production and marketing cost of between US$47 and $70 million, according to the latest available data.

The vectors are magnitude of vector v is 5. The sum of vectors v1 and v2 is (+) = (2, 1, 8).  The difference between vectors v1 and v2 is (-) = (6, -1, -2). The scalar multiple of vector v1 by 3 is 3(2, 0, 3) = (12, 0, 9).

To find the magnitude (||) of a vector, we can use the formula:

||v|| = sqrt(v1^2 + v2^2 + v3^2)

Given vector v = (4, 0, 3), we can calculate its magnitude as follows:

||v|| = sqrt(4^2 + 0^2 + 3^2)

     = sqrt(16 + 0 + 9)

     = sqrt(25)

     = 5

Therefore, the magnitude of vector v is 5.

Now, let's find the sum (+) and difference (-) of the given vectors.

Given vectors v1 = (4, 0, 3) and v2 = (-2, 1, 5), the sum of these vectors is calculated by adding the corresponding components:

v1 + v2 = (4 + (-2), 0 + 1, 3 + 5)

       = (2, 1, 8)

The difference between the vectors is found by subtracting the corresponding components:

v1 - v2 = (4 - (-2), 0 - 1, 3 - 5)

       = (6, -1, -2)

Lastly, let's calculate the scalar multiple of vector v1:

3v1 = 3(4, 0, 3)

   = (12, 0, 9)

Therefore, the vectors are as follows:

- The magnitude of vector v is 5.

- The sum of vectors v1 and v2 is (+) = (2, 1, 8).

- The difference between vectors v1 and v2 is (-) = (6, -1, -2).

- The scalar multiple of vector v1 by 3 is 3(2, 0, 3) = (12, 0, 9).

Considering the equilibrium conditions to determine the force of the member s in the section cut, The summation of all forces in x direction will be zero,

Truss:

Truss is referred to a structure or frame that comprises of two force members that are assembled in different configurations such that the forces are evenly distributed and the entire structure acts as a single member ultimately.

The reactions forces induced in the joints of the truss can be calculated by using force equilibrium equations along horizontal and vertical direction, and moment equilibrium equations.

The body's rigidity is the main assumption for using these equilibrium equations.

Before applying these equilibrium equations, it is necessary to distinguish between known and unknown forces acting on the body. When all the supports are removed by replacing them with forces that prevents the translation of body in a given direction, that diagram is called free body diagram.

The concept of method of sections is used to calculate the force in the particular member in a truss. The applications of truss are bridges and cranes.

Force is a vector quantity. It is represented by a magnitude, direction, and point of application.

The force direction can be compressive or tensile.

Various methods are used to determine the forces in members.

• Method of sections

• Method of joints

Method of sections:

The section method is used to calculate forces in any truss member. It employs the principle of equilibrium, which states that if a portion of a truss is in equilibrium, the entire truss is said to be in equilibrium. While considering a section of a truss care should be taken so that not more than three unknown members of truss are a part of section cut.

Perpetual Motion Machine would produce work indefinitely without any external input of energy, thus violating the first law of thermodynamics which states that energy cannot be created or destroyed, only converted from one form to another.

While it is theoretically possible to design a machine that appears to produce more energy than it consumes, such a machine cannot exist in reality due to the various energy losses that occur in any real-world system.

Answer:

For  lower disk :   V = e^θ​rω(0)/h  = 0

At the upper disk:  V = e^θ​rω(h)/h  = e^θ​rω

Hence The physical boundary conditions are satisfied

Explanation:

Velocity field ( V ) = e^θ​rωz/h

Upper disk located at  z = h

Determine the dimensions of the velocity field

velocity field is two-dimensional ; V = V( r , z )

applying the no-slip condition

condition : The no-slip condition must be satisfied

For  lower disk Vo = 0 when disk is at rest z = 0

∴  V = e^θ​rω(0)/h  = 0

At the upper disk  V = e^θ​rω  given that a upper disk it rotates at z = h

∴ V = e^θ​rω(h)/h  = e^θ​rω

Hence we can conclude that the velocity field satisfies the appropriate physical boundary conditions.

Both reference counting and mark-and-sweep are widely used garbage collection techniques, and each has its own advantages and limitations.

The choice between the two depends on the specific requirements and constraints of the system. Let's examine the characteristics of both methods:

1. Reference Counting:

- Reference counting works by maintaining a count of the number of references to an object. When the count reaches zero, indicating that no references exist, the object can be safely deallocated.

- The main advantage of reference counting is its efficiency in reclaiming memory. Objects are deallocated immediately when their reference count reaches zero, which helps in minimizing memory usage.

- However, reference counting can be problematic in the presence of circular references, where objects reference each other in a cycle. In such cases, reference counting alone cannot reclaim memory, leading to memory leaks. Additional techniques, like cycle detection algorithms, are required to handle circular references.

2. Mark-and-Sweep:

- Mark-and-sweep is a tracing garbage collection algorithm that identifies and reclaims objects that are no longer reachable by traversing the object graph.

- One advantage of mark-and-sweep is its ability to handle circular references effectively. It can detect and collect objects involved in circular references as long as they are not reachable from the root set.

- Mark-and-sweep introduces a pause during garbage collection as it traverses the object graph, which may cause temporary interruptions in the execution of the program.

- Additionally, mark-and-sweep can lead to fragmentation of the memory space, as it collects objects based on reachability rather than compacting the memory.

Considering these aspects, it is difficult to definitively claim that one method is superior to the other in all scenarios. The choice between reference counting and mark-and-sweep depends on various factors, such as the nature of the application, memory usage patterns, performance requirements, and available resources.

In the context of tombstone management, both reference counting and mark-and-sweep can be viable options. Reference counting can be effective if the system does not involve circular references or if circular references can be handled separately. On the other hand, mark-and-sweep can handle circular references but may introduce some pause time during garbage collection.

Ultimately, the decision should be based on careful analysis of the specific requirements, constraints, and trade-offs of the system at hand. It may even be possible to combine elements of both techniques or utilize alternative garbage collection algorithms tailored to the tombstone management needs of the system.
