To drill a hole with a square cross-section, 0.25 inch on a side and 1-inch deep in a steel workpiece, the appropriate process would be (g) wire EDM.

Wire EDM (Electrical Discharge Machining) is a precision machining process that uses a thin, electrically conductive wire to cut through the workpiece. It is commonly used for complex shapes and intricate profiles, including holes with non-traditional cross-sections.

Wire EDM works by creating an electrical discharge between the wire electrode and the workpiece. The controlled spark erosion generated by the electrical discharge gradually removes material from the workpiece, forming the desired shape.

In the case of a square hole, a wire EDM machine can be programmed to cut along the desired path, precisely removing material to create a square cross-section. The wire can be guided in multiple directions, allowing for the creation of holes with different cross-sectional shapes.

Wire EDM is known for its high precision and accuracy, making it suitable for machining intricate shapes in hard materials like steel. It can achieve tight tolerances and excellent surface finishes. Additionally, wire EDM does not exert significant mechanical force on the workpiece, minimizing the risk of deformation or damage.

Thus, the correct option is "e".

A system contains two components A and B that are connected in series. The two components are required to function together in order for the system to work. Let’s assume that A and B work independently from each other. The probability that component A will function is 0.8, while the probability that component B will function is 0.9. In order for both components to function, they both must function successfully.

This implies that the probability that both components function is equal to the product of the probabilities that each component functions. Here's how it works:P(A and B) = P(A) × P(B) = 0.8 × 0.9 = 0.72.Now that we know the probability that both components will work is 0.72, let's double-check. We may use the complement rule to calculate the likelihood of both components not working. Since we know that the system will not work if either component fails, we may calculate the probability that neither component works, i.e., P(A’ and B’). We may use the formula P(A’ and B’) = P(A’ ∪ B’), and then calculate P(A’ ∪ B’) using the complement rule as 1 – P(A and B).P(A' ∪ B') = 1 - P(A and B) = 1 - 0.72 = 0.28.Therefore, the probability that the system will not work is 0.28, and the probability that it will work is 1 – 0.28 = 0.72.

A contractor has a job that should be completed in 100 days. At present, he has 80 men on the job and it is estimated that they will finish the work in 130 days. Of the 80 men, 50 are each paid ₱120.00 a day, 25 at ₱180.00 a day, and 5 at ₱250.00 a day. For each day beyond the original 100 days, a contractor has to pay ₱500.00.

liquidated damages.(a) How many more men should the contractor add so that he would complete the work on time?In the first case, we see that the contractor already has 80 men and they are working for 130 days to complete the job. So, we can use the following formula to determine the additional number of workers required to finish the work in 100 days.

b) If of the additional men, 2 are paid ₱180.00 a day, and the rest at ₱120.00 a day, would the contractor save money by employing more men and not paying the fine Let’s assume that the contractor adds 440 workers, of which 2 are paid ₱180.00 a day and the rest are paid ₱120.00 a day.

The total cost of the new workers is, therefore, ₱9600.00 + ₱4500.00 + ₱49800.00 = ₱63,900.00.The cost of liquidated damages would be calculated as follows:  $$LD = (130-100) \cdot 500 = ₱15,000.00$$.

Therefore, the contractor would save money if he employs more men and not pays the fine. The contractor’s savings would be:$$Savings = LD - Additional cost$$$$= 15000.00 - 63900.00 $$$$= -48900.00$$

Thus, we can see that the contractor would save ₱48,900.00 by employing more men and not paying the fine.

Thus external torque is -146.76 Nm and it is clockwise

Scalar moment = load × moment arm

Load acting on the body is due to HAT and object

External torque on joint is

[(HAT load) × (HAT moment arm)] + [(object load) × (object moment arm)]

(both moments are in clockwise direction)

Or external torque = -[(333 × 0.22) + (245 × 0.3)] = -146.76 Nm

Thus external torque is -146.76 Nm and it is clockwise.

This is so because the force and speed of the pistons' motion determine the torque. High levels of this torque force can be produced by the fastest cars at relatively low rpm. This enables speedy acceleration of the vehicle. The definition of torque is rF=rFsin(r). In other terms, torque is the cross product of the force vector and the distance vector, where 'a' is the angle between r and F. The distance vector represents the distance from the pivot point to the place where force is applied.

Scientists apply the concept of maximum parsimony in various fields, including evolutionary biology and phylogenetics, to make inferences and construct hypotheses about the relationships and evolution of organisms. Maximum parsimony is a principle that suggests choosing the simplest and most economical explanation or hypothesis when multiple possibilities exist.

There are a few reasons why scientists apply the concept of maximum parsimony:

1. Occam's Razor: Maximum parsimony is based on the principle of Occam's Razor, which states that among competing hypotheses, the one with the fewest assumptions should be preferred. By favoring simpler explanations, scientists reduce the risk of introducing unnecessary complexity and assumptions into their analyses.

2. Information Economy: Maximum parsimony seeks to minimize the amount of information required to explain a given set of observations or data. It assumes that the simplest explanation is more likely to be accurate and efficient, as it requires fewer ad hoc assumptions or additional evolutionary events.

3. Avoiding Overfitting: Overfitting occurs when a complex model or hypothesis explains the available data extremely well but fails to generalize well to new data. By favoring parsimony, scientists aim to avoid overfitting and select hypotheses that are more likely to be applicable beyond the specific dataset under consideration.

4. Conceptual Simplicity: Parsimonious explanations are often more conceptually simple and intuitive, making them easier to understand and communicate to others. This can enhance the clarity and accessibility of scientific findings.

However, it is essential to note that maximum parsimony is one of several approaches used in phylogenetic analysis, and it may not always provide the most accurate or complete representation of evolutionary relationships. Other methods, such as maximum likelihood or Bayesian inference, also play significant roles in phylogenetic reconstruction, considering different sources of information and statistical models.

The elastic properties of the brass specimen enables it to return to its

original length when stressed below the yield strength.

The correct responses are;

4. a. The final length is 90.0 m.

b. The final length is 97.2 mm.

Reasons:  

a. Diameter of the brass alloy = 7.5 mm

Length of the specimen = 90.0 mm

Force applied = 6000 N

The equation for the applied stress, σ, is presented as follows;

\(\sigma = \dfrac{Force \ applied}{Area \ of \ specimen} = \dfrac{6000 \, N}{\pi \cdot \left(\dfrac{7.5 \times 10^{-3}}{2} \, m} \right)^2 } \approx 135.81 \ \mathrm{MPA}\)

Depending on the cold working condition, 135.81 MPa is below the yield

strength, and the brass will return to its original condition when the force is

removed. The final length is remains as 90.0 m.

b. When the applied force is F = 16,500 N, we have;

\(\sigma = \dfrac{16,500\, N}{\pi \cdot \left(\dfrac{7.5 \times 10^{-3}}{2} \, m} \right)^2 } \approx 373.48\ \mathrm{MPA}\)

The stress found for the force of 16,500 N is above the yield stress of

brass, and it is therefore, in the plastic region.

From the stress strain curve, the strain can be estimated by drawing a line

from the point of the 373.48 MP on the stress strain curve, parallel to the

elastic region to intersect the strain axis, which gives a value of strain

approximately, ε = 0.08.

The length of the specimen is given by the formula; \(l_i = l_0 \cdot (1 + \epsilon)\)

Therefore;

\(l_i\) = 90 × (1 + 0.08) = 97.2

The final length of the specimen, \(l_i\) = 97.2 mm
