The maximum displacement angle is given as 13°
L = length = 1.25 meters
Initial velocity = 0.8m/s
displacement = ∅max
Work done is given as change in kinetic energy
[tex]\frac{1}{2} mvi^2+0=0+mgh\\\\h = \frac{vi^2}{2g} \\\\h = \frac{0.8^2}{2*10} =\frac{0.64}{20} =0.032 meteres[/tex]
L-h
= 1.25-0.032
= 1.218 meters
Cos∅max = x/L
[tex]=\frac{1.218}{1.25} \\\\= 0.9744\\\\[/tex]
∅max = Cos⁻¹(0.9744)
= 12.99°
≈ 13°
Therefore the maximum displacement angle is given as 13°

Explain how both the waterfall model of the software process and the prototyping model
can be accommodated in the spiral process model.
Answer:
The spiral model can be obliged in prototyping and waterfall show. The spiral model takes the issue as a progression of advance to take care of an issue as in waterfall and take the commitment of clients or clients in each stage as in prototyping model.
Explanation:
Prototyping and waterfall displays can both use the spiral concept.
What is prototyping?Design professionals test by turning their ideas into physical prototypes, which might range from sheet to digital. For the purpose of capturing conceptual designs & user testing, teams create prototypes with varying levels of realism.
The iterative model treats problems as a series of steps to be taken in order to address them, similar to the waterfall approach, and treats the clients' or customers' commitments at each step as in the prototype approach.
When a signed and agreed list of demands needs to be proven, the prototype validation is often carried out throughout predetermined events or cycles. This occurs ideally during later revisions, but not before the official phases of effective application.

A cylindrical rod of brass of 20 mm in diameter is cold worked by drawing. The circular cross section will be maintained during deformation. A cold-worked tensile strength in excess of 300 MPa and a ductility of at least 10% EL are desired. Furthermore, the final diameter must be 14mm. Explain how this may be achieved.
Answer:
To meet all of the criteria raised by the question, we must first draw a wire with a diameter of 8.46 mm and then 21.5 percent CW on it.

ở phía hút của máy bơm, đồng hồ áp suất bourdon ghi độ chân không 40kPa. Áp suất tuyệt đối tương ứng là bao nhiêu nếu áp suất khí quyển địa phương là 100kPa(abs)
Answer:
Nhiều kỹ thuật đã được phát triển cho các phép đo áp suất và chân không. Dụng cụ được sử dụng để đo áp suất được gọi là đồng hồ đo áp suất hoặc đồng hồ đo chân không hoặc áp kế.
Một "'áp kế"' cũng có thể được đề cập đến một dụng cụ đo áp suất, thường được giới hạn để đo áp suất gần đến khí quyển. Thuật ngữ "áp kế" thường được sử dụng để chỉ cụ thể để các dụng cụ cột chất lỏng thủy tĩnh.
Đo chân không được sử dụng để đo lường áp suất trong chân không mà được chia thành hai tiểu thể loại, chân không cao và thấp (và đôi khi chân không cực cao). Phạm vi áp suất áp dụng của một số kỹ thuật được dùng để đo chân không có sự chồng chéo lên nhau. Do đó, bằng cách kết hợp nhiều loại khác nhau của đánh giá, nó có thể để đo áp suất hệ thống liên tục từ 10 mbar xuống đến 10 -11 mbar.
WHAT DO U MEAN WHEN YOU SAY "V8" ENGINE ???
Answer:
“A V6 engine is a 6 cylinder engine while a V8 has 8 cylinders. The choice between a V6 and V8 will come down to the power and performance you want from your car.”
When buying a car, there are some things that you need to consider but can be deemed confusing. The V6 versus V8 engine is one of them, and knowing the differences and advantages can be helpful when you are trying to make a purchasing decision.
Simply put, a V6 is a 6-cylinder engine. Whereas, a V8 means an 8-cylinder engine. But, you may wonder what the ‘V’ means in V6 and V8. The ‘V’ represents the way cylinders are arranged in your engine. V-type engines have cylinders placed in a V-like shape, or to put it the other way, in two equal rows. This design is commonly used since it requires less space and can fit in most cars.

Explanation:
2)Prueba de presión Cuando a una persona se le somete a una prueba de presión, por lo general se le indica que, al llegar el ritmo cardíaco a cierto punto, la prueba deberá detenerse. El máximo ritmo cardíaco permitido, m, en latidos por minuto, puede ser aproximado por la ecuación: m= - 0.875 x + 190 donde x representa la edad del paciente de 1 a 99. Usando este modelo matemático determinar: a) El ritmo cardiaco máximo para una persona de 50 años. b) La edad de una persona cuyo máximo ritmo cardiaco sea de 160 latidos por minuto.
Usando la ecuación de regresión que modela la frecuencia cardíaca máxima, podemos obtener el valor predicho de los problemas dados así:
La ecuación lineal que modela la frecuencia cardíaca máxima permitida en función de la edad del paciente está relacionada con la fórmula:
m = - 0,875x + 190x = edad del paciente; m = máx. frecuencia cardíaca permitida
1.) Frecuencia cardíaca máxima permitida para una persona de 50 años:
Sustituye x = 50 en la ecuación:
m = -0,875 (50) + 190
m = 146,25
Por lo tanto, la frecuencia cardíaca máxima permitida es de aproximadamente 146 latidos / min.
2.) Edad para una persona con frecuencia cardíaca máxima de 160 latidos / min:
Sustituye m = 160 en la ecuación:
160 = -0,875x + 190
0,875x = 190 - 160
0,875x = 30
x = 30 / 0,875
x = 34,28
Por tanto, la edad de la persona sería de unos 34 años.

Long term durability constructions of the glass
Answer:
The durability of glass can be witnessed in most cities with ancient churches. Unless broken by excessive loads glass will remain for very long periods. The glass may be pitted by the weather but still it provides service through the centuries of use. The early producers of glass treated the production like alchemy but modern glass is fairly uniform and the properties governed to provide consistent performance in use. Apart from mechanical stress there are only a few factors that damage glass.
