A 20cm-long rod with a diameter of 0.250 cm is loaded with a 5000 N weight. If the diameter of the bar is 0.490 at this load, determine: I. the engineering stress and strain, and [2] II. the true stress and strain
If the diameter of the bar is 0.490 at this load, determine I. the engineering stress and strain, and [2] II. the true stress and strain is 1561. 84 MPa.
What is strain?Strain is a unitless degree of ways a great deal an item receives larger or smaller from an implemented load. Normal stress happens while the elongation of an item is in reaction to an everyday pressure (i.e. perpendicular to a surface), and is denoted via way of means of the Greek letter epsilon.

Answer:
A F E C D B
Explanation:
Performance testing can be done with quantitative tests that are run in a lab or, in some situations, in a real-world setting. Performance requirements must be determined and tested.
What parameters included in a baseline performance check?Commonly used criteria include things like processing speed, data transfer rates, network bandwidth and throughput, workload efficiency, and dependability.
Baseline testing is the process of confirming the accuracy of the documents and requirements upon which test cases are based.
A baseline is a benchmark that serves as the foundation for any new production, generally speaking. This is the benchmarking of the application's performance in software testing.
Performance testing requires the design, normal and peak loads, system resources, dependencies, workload characteristics, and time, all of which should be considered in any method.
Therefore, A baseline is a set timeline that serves as the benchmark against which the project's performance is evaluated.

Answer:Block-based coding requires a different type
Explanation:
TV
When writing a programme, text-based programming languages give programmers more in-depth control over lower-level functionality.
What is block-based applications?In block-based applications, we are constrained to use the blocks that are provided to us and frequently have a limited range of options for doing so. We have more freedom to customise lower-level functionality in text-based languages since we are not constrained by a predetermined number of available blocks.
Python is usually used for making websites and applications, automating repetitive tasks, and analysing and display of data. Python has been utilised by many non-programmers, including accountants and scientists, for a different kind of routine activities including managing finances since it is very simple to learn.

A 100-horsepower, three-phase squirrel-cage induction motor is connected to a 240-volt line. A dual-element time-delay fuse is to be used as the short-circuit protective device. What is the correct fuse rating
Based on the National Electrical Code (NEC), a 450-Ampere fuse should be used to protect this polyphase (three-phase) squirrel cage inductor motor.
Given the following data:
Power rating = 100-horsepower.Voltage = 240 volt.How to determine the correct fuse rating?According to Table 430.52 of the National Electrical Code (NEC), a dual-element time delay fuse should be calculated at 175% (1.75) of the full-load current rating for an alternating current (AC) polyphase (three-phase) squirrel cage inductor motor.
In this scenario, the squirrel cage inductor motor didn't list a NEMA design code on its nameplate. Thus, we'll assume that the inductor motor is design B and its fuse rating is given by:
Fuse rating = 248 × 1.75 × 434
In conclusion, the nearest standard fuse size which is above the computed value listed in Section 240.6 of the National Electrical Code (NEC) is 450 amperes.

B = 946.70+ 0.055 m
C = 54°18+25"
Based on the calculations, the area of this triangle is equal to 290,136.87 m².
Given the following data:
Side A = 757.64 +0.045 m.Side B = 946.70+ 0.055 m.Angle, C = 54°18'25"How to calculate the area of this triangle?Mathematically, the area of a triangle can be calculated by using this formula:
Area = 1/2 × b × h
Where:
b is the base area.h is the height.In this scenario, the area of this triangle is given by:
Area = 1/2 × a × b × sinC
Substituting the given parameters into the formula, we have:
Area = 1/2 × 757.64 × 946.70 × sin(54°18'25")
Area = 580,273.74/2
Area = 290,136.87 m².
Next, we would determine the probable error of the area by using this formula:
[tex]PE_A = \pm k \sqrt{PE} \\\\PE_A = \pm \frac{1}{2} \times sinC \sqrt{(aPE_b)^2 + (bPE_a)^2 } \\\\PE_A = \pm \frac{1}{2} \times sin(54^{\circ}18'25") \times \sqrt{(757.64 \times 0.045)^2 + (946.70 \times 0.055)^2 } \\\\PE_A = \pm 0.4045 \times \sqrt{1,162.39 +2,711.12}\\\\PE_A = \pm 0.4045 \times \sqrt{3,873.51}\\\\PE_A = \pm 0.4045 \times 62.2375\\\\PE_A = \pm25.1751 \;m^2[/tex]
