A hemispherical dome of radius 40 feet is to be given 5 coats of paint, each of which is 1/100 inch thick. Use linear approximation to estimate the volume of paint needed for the job.( Hint: Approximate the change in the volume of a hemisphere when the radius increases from 40 feet to 40 feet 5/100 inches. Don't forget to make sure this increased radius is in terms of feet. )It will take approximately  cubic feet of paint to apply all 5 coats of paint.

Magnetic resonance imaging (MRI) is a medical imaging technique that located in hospitals and radiology centers. MRI uses a strong magnetic field and radio waves to create detailed images of the organs and tissues within the body. (i) MRI system operators must make sure not to carry any metallic objects when they enter the room that house the MRI, even when the machine is not operating. Give the reason. (ii) What happens if a magnet was hitted with a hammer repeatedly? Explain your answer. Robots are used in automobile industries to weld two components at specific locations. Thus, the end position of the robot arms must be determined accurately in order to weld the components at the precise position. In selecting a proper material for the robot arms design, identify the factors must be considered for this application.

Solve it correctly please. I

Hi i need help on what is the answer for this problems? Below is the questions and no plagiarism please? And can it be in type form not picture and lastly minimum of 5 sentences each question. Thank you

Two students decided to print a prototype for a gear. Student A use layer thickness of .1 mm and an infill density of 25%. Student B use a layer thickness of 0.07 mm and an infill density of 45%. Which student will take less time to print the gear? Select one: Stu nt since the ckness of layer is smaller and the infill density is higher. O We can't decide which process takes less time O Student A since the thickness of the layer is larger and the infill density is lower. Student B because thickness is higher than B and the infill density has no effect on the process speed. Student A because thickness is higher than B and the infill density has no effect on the process speed.

Task 1 The company is interested in expanding its production capability into ceramic based products. You have been asked to identify typical products manufactured using selected ceramic processes and then describe how the properties of the ceramic make this a suitable process for the product. Briefly describe the process and then examine which types of products which can be manufactured using this process. Then describe the properties that make the ceramic and process suitable for that application. · Ceramic Sintering · Ceramic Hot Pressing · Chemical Vapour Deposition · Reaction Bonding process

Nondestructive evaluation: Nondestructive evaluation (NDE) describes methodsthat quantitatively characterize materials, tissues, and structures by noninvasivemeans such as X-ray computed tomography, ultrasonics, and acoustic emission.Recently, NDE was used to detect defects in steel castings. (JOM, May 2005.)Assume that the probability that NDE detects a “hit” (i.e., predicts a defect in a steelcasting) when, in fact, a defect exists is .97. (This is often called the probability ofdetection.) Also assume that the probability that NDE detects a “hit” when, in fact,no defect exists is .005. (This is called the probability of a false call.) Past experiencehas shown that a defect occurs once in every 100 steel castings. If NDE detects a“hit” for a particular steel casting, what is the probability that an actual defectexists? Step by Step Full procedure required.

The title of our study is "Design and Fabrication of an Agricultural Spraying Attachment for an Autonomous Rover" we need help in the machine design part of our study, specifically Pump selection, battery selection, and center of gravity computation I already sent you the image of the rover Rover weight capacity 35 kilo grams (payload) Rover measurements: Wheel distance - 14.5 inches and 8.5 inches Rover platform size (width & length) 14.4 inches x 10.4 inches Height- 15.8 inches. Water tank selection More or less 25 liters *For tank selection we need to justify the size with the center of gravity, proving that is the maximum dimension or liters of the tank because the center of gravity will be higher making the rover prone to toppling Pump selection *Our sprayer design has two nozzles which splits using a tee splitter, we need to find the size of the pump to obtain the same discharge rate of a normal sprayer. A normal sprayer has a 12V pump and a pressure from 0.2 to 0.45 mpa…

First read Section 2.14 of the Kaminski & Jensen text entitled, The “Pizza” Procedure for Problem Solving (silly name maybe, but it underscores the need to break large problems intomanageable parts). In describing the major parts of the procedure for solving engineeringproblems, an analogy is made to a stool with three legs. Name and describe in a few words the3 “legs” of the procedure for solving engineering problems:
