AHS 142 Journal Article Assignment - Copy

P-4 Please I need help with this question needed very clearly and step by step explanation and needed with clear handwriting please, will be really appreciated for your help

I want a literature review on the topic (Enhancing indoor air quality and safe entertainment in sports halls) consisting of several paragraphs... Introduction 5 to 7 line with reference and conclusion

please solve part b, this is past paper and just iam studying, mechanical engineering

[Plane wall conduction with heat generation] When passing an electrical current I (A), a copper bus bar of rectangular cross section (6 mm × 150 mm) experiences uniform energy generation at a rate ġ (W /m³) given by ġ = al? where a = 0.015 W /m³ · A² . If the bar is in ambient air with h = 5 W/m2 · K and its maximum temperature must not exceed that of the air by more than 30°C, what is the allowable current capacity for the bus bar?

Nanotechnology, the field of building ultrasmall structures one atom at a time, has progressed in recent years. One potential application of nanotechnology is the construction of artificial cells. The simplest cells would probably mimic red blood cells, the body’s oxygen transporters. Nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person’s bloodstream. If the person needed additional oxygen—due to a heart attack or for the purpose of space travel, for example—these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. Suppose that the nanocontainers were cubic and had an edge length of 25 nanometers. Suppose that each nanocontainer could contain pure oxygen pressurized to a density of 85 g/L. How many grams of oxygen could be contained by each nanocontainer?

What is engineering? What are the differences among engineers, mathematicians, and scientists? What is mechanical engineering?

Hello. Can you please help answer the question shown in the photo? It is a 3-part question which I have attempted many times. I was able to calculate the correct answer for part 2, but part 1 and part 3 still says I am incorrect. Please show how to properly solve the problem. The topic is heat transfer. Thank you.

What’s the correct answer please?

2. Sharp notches are often added to plastic food packages to help open them (along with arrows indicating where they should be torn). Why do they do this, and why is it sometimes very hard to open them without this notch? Would it be harder or easier to open with a semi-circular notch and why?

dear tutor please provide neat and clean and detailed answer. dont copy from google adress both questions well

Question 2 You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the…
