Explanation:

The Air fuel ratio is used in the combustion process of engines whether internal or external, and defined as the mass  ratio of air to  fuel present in a combustion process.  When the ratio of the mass of air and fuel is right, combustion is said to be efficient and balanced and this is refereed to as stoichiometrc mixture which is a standard that all engines are required to target.

when the air fuel Ratios is  lower than the target stoichiometric, it is considered as a Rich mixture  while higher ratios  than stoichiometric are considered Lean mixtures. Lean mixtures are more efficient than rich mixtures although the main aim is to be at the stoichiometic mixture point.

Air fuel equivalence ratio, lambda and the amount of oxygen in an exhaust are two indicators for lean or rich mixtures in an air fuel ratio for combustion in engines

Now, Air–fuel equivalence ratio, λ (lambda), is defined as the  ratio of actual AFR to stoichiometry for a particular mixture,

when Lambda λ = 1.0 , the mixture is at stoichiometry,

when  λ < 1.0, the mixtrure is rich.

when  λ > 1.0, the mixture is  lean

 Therefore Technician A is wrong

Also The amount of oxygen present in the exhaust determines if the air-fuel mixture supplied to the combustion chambers is at the target or best ratio. Too much oxygen indicates that the mixture is lean and too little  indicates the mixture is rich. Therefore Technician B is right.

Points on a fingerprint where ridge characteristics change are called minutiae, and they help us match prints.

Minutiae are specific points or features on a fingerprint where the ridges exhibit changes in their characteristics. These changes can include ridge endings, bifurcations, or other types of ridge patterns that differ from the surrounding ridge flow.

Minutiae points are crucial in fingerprint identification and matching because they provide unique and distinctive characteristics for each individual's fingerprint. By analyzing and comparing the arrangement, type, and relationship of minutiae points between two fingerprint impressions, forensic experts and automated fingerprint recognition systems can determine if the prints match or belong to the same individual.

Common types of minutiae points include ridge endings, where a ridge terminates abruptly, and bifurcations, where a ridge splits into two separate ridges. Other types include ridge islands, dots, enclosures, and short ridges.

The presence and arrangement of minutiae points provide valuable information for fingerprint analysis, matching, and identification. They serve as reliable features that contribute to the uniqueness and individuality of fingerprints, making them an essential component of forensic science and biometric identification systems.

Answer:

\( T_A_C = 6.296 kN \)

\( R = 10.06 kN \)

Explanation:

Given:

\( T_A_B = 8.7 kN\)

Required:

Find the tension TAC and magnitude R of this downward force.

First calculate \( \alpha, \beta, \gamma \)

\( \alpha = tan^-^1 =\frac{40}{50} = 38. 36 \)

\( \beta = tan^-^1 =\frac{50}{30} = 59.04 \)

\( \gamma = 180 - 38.36 - 59.04 = 82.6 \)

To Find tension in AC and magnitude R, use sine rule.

\( \frac{sin a}{T_A_C} = \frac{sin b}{T_A_B} = \frac{sin c}{R} \)

Substitute values:

\(\frac{sin 38.36}{T_A_C} = \frac{sin 59.04}{8.7} = \frac{82.6}{R}\)

Solve for T_A_C:

\( T_A_C = 8.7 * \frac{sin 38.36}{sin 59.04} = \)

\( T_A_C = 8.7 * 0.724 = 6.296 kN \)

Solve for R.

\( R = 8.7 * \frac{sin 82.6}{sin 59.04} = \)

\( R = 8.7 * 1.156 \)

R = 10.06 kN

Tension AC = 6.296kN

Magnitude,R = 10.06 kN

(a) The probability that at least 1 in 10 successive sections signal a problem when in fact the sections are intact is 26.26%.

(b) The probability that at least 1 in 20 successive sections signal a problem when in fact the sections are intact is 50.16%.

Ultrasonic pulse velocity testing is a non-destructive test used to assess the integrity of concrete structures. The test can indicate whether a concrete section is intact or if there is a problem. However, even when a section is intact, there is a small probability that the test equipment may signal a problem, known as a "false positive." In this case, the probability of a false positive is 0.03.

(a) To calculate the probability that at least 1 in 10 successive sections signal a problem when the sections are actually intact, we can use the formula:

P(getting at least 1 false positive) = 1 - P(getting no false positive).

Assuming independence between successive sections, the probability of getting no false positive in one section is (1 - p)^10. Therefore,

P(getting at least 1 false positive) = 1 - (1 - 0.03)^10

P(getting at least 1 false positive) = 0.2626 or 26.26%.

(b) Similarly, to calculate the probability that at least 1 in 20 successive sections signal a problem when the sections are intact, we use the same formula. The probability of getting no false positive in one section is (1 - p)^20. Therefore,

P(getting at least 1 false positive) = 1 - (1 - 0.03)^20

P(getting at least 1 false positive) = 0.5016 or 50.16%.

Therefore, the probability that at least 1 in 10 successive sections signal a problem when the sections are intact is 26.26%, while the probability that at least 1 in 20 successive sections signal a problem when the sections are intact is 50.16%.

When the membrane is depolarized, voltage-gated potassium channels do not open instantly; instead, they require roughly 1 msec to open.

The opening of a group of voltage-gated potassium channels lets potassium stream out of the cell via its electrochemical gradient. These occurrences swiftly reduce the membrane potential, returning it to its typical resting state.

Depolarization triggers the activation of voltage-gated potassium channels, and the outward flow of potassium ions through them repolarizes the membrane potential to end action potentials, hyperpolarizes the membrane potential immediately after action potentials, and is essential in establishing the resting membrane potential.

The question is incomplete. The complete question is --

An aluminum rod is press fitted onto an aluminum collar. The collar has an inner radius of 1 cm and an outer radius of 2 cm. Given the rod has a diameter of 1.01 cm and the young's modulus of aluminum is 69 GPa, determine the following :

1. the interference value, i

2. the radial pressure at the interference of the collar and the rod

3. the maximum effective stress in the collar

4. if the yield strength of aluminium is 200 MPa and assume a safety factor of 1.5, will the aluminium collar break

Solution:

Given :

Inner radius of the collar = 1 cm

So, inner diameter, \($d_1$\) = 2 cm

Outer radius of the collar = 12 cm

So, outer diameter, \($d_2$\) = 4 cm

The aluminium rod diameter, d = 1.01 cm

Now, from the figure, we can see that there will be no interference and so the rod will easily insert inside the collar.

1. So, the interference , i =0

2. The radial pressure is also 0.

3. There will be no stress developed. So the maximum effective stress is 0

4. The collar will not break
