Answers

Answer 1

The eddy current testing (ET) method is usually used for the inspection of conductive materials. The internal discussion in an engineering team in a company that makes the first-stage jet engine blades, which experience the maximum temperature in a jet engine and huge centrifugal force stresses and must have maximum quality possible, is to replace eddy current testing (ET) with either MT or PT to save cost for manufacturing the first stage blade of a jet engine.

The material of the blade is ferromagnetic, conductive, and time to perform a test is not a concern. From a reliability point of view, it is not a good idea to replace the eddy current testing (ET) method as it is a reliable method for inspecting jet engine blades that are subject to high-stress conditions.

The eddy current testing (ET) method can detect near-surface flaws, cracks, and other material discontinuities and can inspect the blades without the need to remove any coatings. Therefore, the eddy current testing (ET) method is the best-suited method to replace the ET method.

Answers

The man who opposed communism first by refusing to accept the constant lying required to live under a communist regime is Vaclav Havel.

Vaclav Havel, the Czech playwright and political dissident, was a prominent figure in the opposition against communism. Havel firmly stood against the oppressive nature of the communist regime and refused to conform to the constant lying and deception that was expected under such a system.

As an advocate for human rights and freedom of expression, Havel openly challenged the propaganda and manipulation that characterized the communist government.

Born in 1936, Havel experienced firsthand the realities of living under communist rule in Czechoslovakia. His plays, essays, and speeches reflected his profound belief in the power of truth and the importance of personal integrity. Havel's refusal to accept the falsehoods and hypocrisy of the regime made him a symbol of resistance and a champion of truth in the face of oppression.

Havel's dissent against communism culminated in his role as a leader in the Velvet Revolution of 1989, which led to the overthrow of the communist government in Czechoslovakia. Following the revolution, Havel became the country's first democratically elected president.

Throughout his presidency and beyond, Havel continued to advocate for human rights and democracy, leaving a lasting legacy as a fearless opponent of communism.

You have to select a particle control device for the following scenario: • Particle removal of 99+% must be achieved. • Adequate space is available to accommodate any device. • The gas stream is relatively dry, averaging 20% relative humidity. • The particle resistivity is unknown. • Moderate pressure drop can be accommodated, but high pressure drop is not wanted. Which would be the preferred air pollution control device for this situation - electrostatic precipitator or fabric filter? Explain your rationale

Answers

The preferred air pollution control device for this situation is a fabric filter. The rationale behind this is Particle removal of 99+% must be achieved: Both electrostatic precipitators and fabric filters can achieve particle removal efficiency of 99% or higher.

Adequate space is available to accommodate any device: Both devices are available in different sizes and can be custom designed to suit the available space. The gas stream is relatively dry, averaging 20% relative humidity: Electrostatic precipitators work best with high moisture levels, while fabric filters are not affected by moisture levels.

The resistivity of particles can cause problems with electrostatic precipitators as it can reduce the efficiency of the device. Fabric filters are not affected by resistivity levels. Moderate pressure drop can be accommodated, but high pressure drop is not wanted. Fabric filters have a lower pressure drop compared to electrostatic precipitators which makes them a preferred option in this scenario.

This is an excerpt from- Sexual selection and special design authored by Steven W Gangestad, in the Annals New York academy of Science. Answer the questions based on the excerpt provided below. "…..Women claim men’s scent importantly affects their attraction to them. Moreover, evidence suggests that women’s olfaction changes across menstrual cycle. For instance, women tend to rate androstenone, a steroid found in men’s sweat, more positively near ovulation than during non-fertile phases.
In an initial study, we asked 41 men to wear T-shirt for two consecutive nights. During the two-day period, they were to wash only with unscented soap, not to wear any fragrances or colognes, not eat certain strong foods, and not to sleep with another person. They dropped shirts off at our lab on a designated morning. Later that same morning and throughout the next day, women came in, smelled each T-shirt and rated its attractiveness (a composite of two ratings: pleasantness and sexiness). For each woman, we regressed her rating on men’s symmetry to yield "a preference for symmetry" score (the regression slope, a measure of the change in rating as a function of a change in symmetry). We then examined the correlation of these preference scores with women’s estimated fertility based on their self-reported day of the cycle and actuarial data on probability of conception for each day. Across 28 normally ovulating women the correlation was 0.54, p<0.001. Examination of the bivariate plot revealed that when women’s fertility was near zero (very early and late in the cycle), they had no systematic preference for the scent of either symmetrical or asymmetrical men. As their fertility increased, however, they increasingly preferred the scent of symmetrical men.
A subsequent study replicated and extended that result in a larger sample of about 50 normally ovulating women and 80 men. Women’s preference for symmetry correlated 0.42 with their fertility based on the day of their cycle, p<0.001. We asked men how many times they showered and whether they wore any fragrances. The number of times men showered predicted the attractiveness of their scent. When this variable was partialled out and all men who wore fragrances were eliminated from the analysis, the correlation between women’s symmetry and their fertility actually increased, r=0.48, p<0.001. In a third study in our lab, this result was once again replicated, r=0.26, p<0.05. When data from all three studies were pooled, the correlation between women’s preference for symmetry and the fertile phase of their cycle was r=0.40, p<0.0001." [Note: p values reported here means that correlation r is statistically significant]
From this scenario, the immune systems of humans should be exceptionally high. Yet, there is a rising incidence of autoimmune diseases and lack thereof immunity. What form of selection do you think is at play here? Explain.

Answers

Autoimmune diseases are rising despite the fact that humans should have exceptionally high immune systems. This can be explained by the fact that sexual selection is at play, leading to a reduction in immune function.

The excerpt explains the correlation between women's preference for symmetry and their fertile phase of their cycle. It is observed that women tend to prefer the scent of symmetrical men as their fertility increases. This indicates that women use scent as a factor in determining mating partners, which is an example of sexual selection.Sexual selection is a special type of natural selection in which individuals with certain traits are more likely than others to obtain mates.

This leads to traits that improve an individual's ability to secure a mate being favored, while traits that do not aid in mate selection are not favored.As a result, it is suggested that sexual selection may have favored traits that lower immune function in order to signal traits related to mate quality. This could explain the rising incidence of autoimmune diseases despite the fact that humans should have exceptionally high immune systems.

[2 pts] True or False You can increase power by increasing the angular velocity of the shaft. [2 pts] True or False You can increase power by slowing down the frequency of the shaft. [2 pts] True or False Interlocking gears of different radii must experience the same angle of twist.

Answers

Engineers use gears in design for transmitting motion, controlling speed and power, and adjusting torque, while the statements are explained as follows: False, True, False, True.

What are the major components of a computer's central processing unit (CPU)?

Engineers use gears in design for various reasons, including:

Transmitting and converting rotational motion: Gears are used to transfer motion between rotating shafts, change the direction of rotation, or change the speed of rotation.

Increasing or decreasing torque: Gears allow engineers to amplify or reduce the torque applied to a system, depending on the gear ratio.

Controlling speed and power: By selecting different gear ratios, engineers can control the speed and power output of a system.

Regarding the statements:

False: The torque in each gear depends on the force applied and the radius of the gear. If two interlocking gears have the same radius, the torque can still be different if the applied forces are different.

True: Increasing the angular velocity (rotational speed) of the shaft increases the power output of the system, assuming the torque remains constant.

False: Slowing down the frequency (rotational speed) of the shaft reduces the power output of the system since power is directly proportional to both torque and rotational speed.

True: Interlocking gears of different radii will experience different angles of twist as they rotate due to the difference in the circumference and rotational speed of the gears.

Answers

Given the intersection of a N 450 E back tangent line and a S 850 E forward tangent line at point "PI," and the locations of BC and EC at stations 25+00 and 31+00, respectively, we can determine various measurements. The stationing of point PI, the deflection angle to station 26+00, the chord distance to station 26+00 from BC, the bearing from BC to the Radius Point, and the bearing of the long chord from BC to EC can all be calculated.

a) To determine the stationing of point PI, we subtract the station of BC (25+00) from the station of EC (31+00). The resulting difference gives us the stationing of point PI.

b) The deflection angle to station 26+00 can be calculated using the formula: deflection angle = (chord distance / radius) * (180 / π). By subtracting the station of BC from the given station (26+00), we obtain the chord distance. The radius can be determined based on the given tangents and the intersection angle.

c) The chord distance to station 26+00 from BC is obtained by subtracting the station of BC (25+00) from the given station (26+00).

d) The bearing from BC to the Radius Point can be determined by taking the bearing of the back tangent line (N 450 E) and adding the intersection angle at point PI.

e) The bearing of the long chord from BC to EC can be calculated by taking the bearing of the back tangent line (N 450 E) and adding 90 degrees.

By applying the appropriate calculations and substituting the given values, the stationing of PI, deflection angle, chord distance, and bearings can be obtained for the provided problem.
