T/F: Cylindrical grinders are typically used to sharpen tooling.

Answer:

The relation between the discharge volume flow rate and the inlet volume flow rate is \(\frac{1}{5}\).

Explanation:

No matter if fluid is compressible or not, mass throughout compressor, a device that works at steady state, must be conserved according to Principle of Mass Conservation:

\(\dot m_{in}-\dot m_{out} = 0\) (Eq. 1)

Where \(\dot m_{in}\) and \(\dot m_{out}\) are mass flows at inlet and outlet, measured in kilograms per second.

After applying Dimensional analysis, we expand the equation above as follows:

\(\rho_{in}\cdot \dot V_{in} - \rho_{out}\cdot \dot V_{out} = 0\) (Eq. 2)

Where:

\(\rho_{in}\), \(\rho_{out}\) - Fluid densities at inlet and outlet, measured in kilograms per cubic meter.

\(\dot V_{in}\), \(\dot V_{out}\) - Volume flow rates at inlet and outlet, measured in cubic meters per second.

After some algebraic handling, we find the following relationship:

\(\rho_{out}\cdot \dot V_{out} = \rho_{in}\cdot \dot V_{in}\)

\(\frac{\dot V_{out}}{V_{in}} = \frac{\rho_{in}}{\rho_{out}}\) (Eq. 3)

If we know that \(\rho_{in} = 1\,\frac{kg}{m^{3}}\) and \(\rho_{out} = 5\,\frac{kg}{m^{3}}\), then the relation between the discharge volume flow rate and the inlet volume flow rate is:

\(\frac{\dot V_{out}}{\dot V_{in}} = \frac{1\,\frac{kg}{m^{2}} }{5\,\frac{kg}{m^{3}} }\)

\(\frac{\dot V_{out}}{\dot V_{in}} = \frac{1}{5}\)

The relation between the discharge volume flow rate and the inlet volume flow rate is \(\frac{1}{5}\).

a. Best Critical Region (BCR): The critical region that maximizes the power of a statistical test.

b. Uniformly Most Powerful Test (UMPT): A statistical test with the highest power among all possible tests for a given significance level.

c. Pivotal Quantity (PQ): A function of sample data and an unknown parameter with a known distribution independent of the parameter.

d. Randomized Test: A statistical test where the decision to accept or reject the null hypothesis is determined randomly.

e. Sequential Probability Ratio Test (SPRT): A method for sequential decision-making based on accumulating evidence from a sequence of observations, useful for efficient binary decision-making.

a. The best critical region (BCR) refers to the region in the sample space where the null hypothesis is rejected, resulting in the most favorable trade-off between the probabilities of type I and type II errors. It is the critical region that maximizes the power of the statistical test.

b. The uniformly most powerful test (UMPT) is a type of statistical test that possesses the most power among all possible tests for a given significance level. It is designed to detect the alternative hypothesis with the highest probability, making it the most powerful test in a statistical hypothesis testing framework.

c. A pivotal quantity (PQ) is a function of the sample data and an unknown parameter that has a known distribution that does not depend on the parameter itself. Pivotal quantities are useful in statistical inference as they allow for the construction of confidence intervals and hypothesis tests that are distribution-free or have known distributions.

d. A randomized test is a type of statistical test where the decision to accept or reject the null hypothesis is determined by a random mechanism. It involves using a randomization procedure to assign observations to different treatment groups or to determine the critical region. Randomized tests have the advantage of controlling the type I error rate and can be useful in situations where traditional fixed-sample tests may not be appropriate.

e. The Sequential Probability Ratio Test (SPRT) is a statistical method used for making sequential decisions based on accumulating evidence from a sequence of observations. It is commonly used in quality control and decision-making processes where data is collected sequentially. The SPRT allows for early termination of the test if a decision can be reached with sufficient confidence based on the available data, leading to efficient and timely decision-making. It is particularly useful when testing hypotheses or making binary decisions in a sequential manner, reducing the number of observations required compared to traditional fixed-sample tests.

Answer:

(a) 210 MPa (b) 377.97 KN (c) 7363.108 mm³

Explanation:

Solution

Given that

Diameter (d) = 25 mm

Height = 15 mm

Tensile Strength = 175 MPa

(a) We find the compacting pressure which is given below:

(Pe) = 2Sth/d

Here

St =175 MPa

h = 15 mm

d = 25 mm

Pe = 2 * 175 *15/25

=210 MPa

Pe = 210 MPa

(b) We calculate for the press force (Fp) shown below:

Fp = A *St

A = 2πr (r+h)

= 2π * 12.5 (12.5 + 5)

A =2159.84 mm²

So,

Fp = 2159.84 * 175

Fp = 377.97 KN

(c) We calculate for the initial volume of powder required which is given as:

Vp = πr² h

=π (12.5)² * 15 mm³

Vp = 7363.108 mm³

Answer:

a) The amount by which this specimen will elongate in the direction of the applied stress is 0.466 mm

b) The change in diameter of the specimen is  - 0.015 mm

Explanation:

Given the data  in the question;

(a) The amount by which this specimen will elongate in the direction of the applied stress.

First we find the area of the cross section of the specimen

A = \(\frac{\pi }{4}\) d²

our given diameter is 20.5 mm so we substitute

A = \(\frac{\pi }{4}\) ( 20.5 mm )²

A = 330.06 mm²

Next, we find the change in length of the specimen using young's modulus formula

E = σ/∈

E = P/A × L/ΔL

ΔL = PL/AE

P is force ( 46300 N), L is length ( 201 mm ), A is area ( 330.06 mm² ) and E is  elastic modulus (60.5 GPa) = 60.5 × 10⁹ N/m² = 60500 N/mm²

so we substitute

ΔL = (46300 N × 201 mm) / ( 330.06 mm² × 60500 N/mm² )

ΔL =  0.466 mm

Therefore, The amount by which this specimen will elongate in the direction of the applied stress is 0.466 mm

(b) The change in diameter of the specimen. Indicate an increase in diameter with a positive number and a decrease with a negative number.

Using the following relation for Poisson ratio

μ = -  Δd/d / ΔL/L

given that Poisson's ratio of the metal is 0.33

so we substitute

0.33 = -  Δd/20.5 / 0.466/201

0.33 = -  Δd201 / 20.5 × 0.466

0.33 = - Δd201  / 9.143

0.33 × 9.143 =  - Δd201

3.01719 = -Δd201

Δd = 3.01719 / - 201

Δd  = - 0.015 mm

Therefore, The change in diameter of the specimen is  - 0.015 mm

The sinusoids corresponding to each of the given phasors are a) V = 57.72 + j51.91,b) V = 6 + j8,c) I1 ≈ -1.4 - j2.42,d) I2 = -0.5 - j1.2.

To find the sum of V1 and V2, we need to add their phasors. Phasors are complex numbers that represent sinusoidal signals.

a) For V1 = 60 <15°, we can represent it as V1 = 60e^(j15°).

  Similarly, for V2 = 6+j8, we can write it in polar form as V2 = 10e^(j53.13°) since the magnitude is sqrt(6^2 + 8^2) = 10 and the angle is tan^(-1)(8/6) ≈ 53.13°.

b) To find the sum V = V1 + V2, we can add their phasors:

  V = V1 + V2 = 60e^(j15°) + 10e^(j53.13°).

  To simplify the expression, we can convert the phasors to rectangular form:

  V = 60(cos(15°) + jsin(15°)) + 10(cos(53.13°) + jsin(53.13°)).

  Expanding and combining the real and imaginary parts:

  V = 60cos(15°) + 10cos(53.13°) + j(60sin(15°) + 10sin(53.13°)).

  Evaluating the trigonometric functions:

  V ≈ 57.72 + j51.91.

  Therefore, V = 57.72 + j51.91.

c) For I1 = 2.8e^(-jπ/3), we have I1 ≈ 2.8(cos(-π/3) + jsin(-π/3)).

  In rectangular form: I1 ≈ 2.8(-0.5 - j0.866).

  Therefore, I1 ≈ -1.4 - j2.42.

d) For I2 = -0.5 - j1.2, there is no need for conversion since it is already given in rectangular form.

In summary, the sinusoids corresponding to each of the given phasors are:

a) V = 57.72 + j51.91

b) V = 6 + j8

c) I1 ≈ -1.4 - j2.42

d) I2 = -0.5 - j1.2

Explanation:

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

You'll need to use Ohm's Law and Kirchhoff's Voltage Law.

Remember Ohm's Law as \(V = IR\).

Kirchoff's Voltage Law says that the sum of voltages for a given circuit "loop" must equal zero. In the circuit shown, this means that the voltage provided by the battery (E_T) equals the voltage drop across each of the three resisters in the loop.

\(E_T = E_1 + E_2 + E_3\)

A couple of other helpful notes:

These three resistors are in series which means that the current flowing through them is equal.

So it is easy to see that... \(V = IR \rightarrow E_1 = 4*2 = 8 V\)

Solve for the voltage across E_2 and E_3. The sum of the three voltages equals the voltage of the battery (E_T).
