HW04- InjectionMolding-Case Study-

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…

What type of CAD software could be used to test the medical scaffold made out of TPU that will be printed using stereolithography (SLA). The medical scaffold will be surgically implanted around the pancreas to enable the infusion of Islet beta cells which are encapsulated within the scaffold to provide diabetic patients with a functional pancreas. E.g. hydrostatic pressure testing/torsion tests What other type of physical testings should be taken?  E.g. Brunauer–Emmett–Teller (BET) test to check the porosity of the material

In 1907 a janitor called Murray Spangler put together a pillowcase. a fan, an old biscuit tin and a broom handle. It was the world's first vacuum cleaner_ One year later he sold his patented idea to William Hoover whose company wont on to dominate the vacuum cleaner market for decades. especially in its United States homeland. Yet between 2002 and 2005 Hoover's market share dropped from 36 per cent to 13.5 per cent, Why? Because a futuristic looking and comparatively expensive rival product, the Dyson vacuum cleaner, had jumped from nothing to over 20 per cent of the market. In fact, the Dyson produce dales back to 1978 when James Dyson noticed how the air filter in the sprayfnishing room of a company when; he had been working was constantly clogging with powder particles (just like a vacuum cleaner bag clogs with dust). So he designed and built an industrial cyclone lower, which removed the powder particles by exerting centrifugal forces. Thy question intriguing him was, could the…

Your capstone design team is prototyping (e.g. you are building a model to test not a final product) a "fire identification drone. The final product is intended to fly over rugged wilderness areas and look for small fires that should be monitored and potentially fought or contained. It is NOT intended to be used in large active fires. Your subteam's job is to design and build the support frame for the drone (e.g. the structure where the motors, propellers, guidance electronics and GPS, heat sensors, radio receiver and transmitter, etc. are attached) for the prototype. You have access to a machine shop with saws, lathes (for removing material by rotating it and using a cutting tool), drills and a facility with 3-D printers that can print a variety of plastics using fused deposition modeling (this is the technique where a polymer filament is melted and forced through a nozzle to build a structure layer by layer). You will be testing in a summer/fall timeframe so you expect temperatures…

This is a solidworks question.

A siilicon boule has been processed through grinding to provide a cylinder whose diameter  = 281 mm and whose length = 899 mm. Next, it will be sliced into wafers 0.8 mm thick using a cut-off saw with a kerf = 0.5 mm. The wafer thus produced will be used to fabricate as many IC chips as possible for the personal computer market. Each IC has a market value to the company of $108. Each chip is square with 17 mm on a side. The processable area of each wafer is defined by a diameter = 265 mm. Estimate the value of all of the IC chips that could be produced (in $), asssuming an overall yield of 84% good product.

Multiple choice questions, please help thank you!! 1. The chemical potential (μ) of smaller size clusters is bigger than that of bigger size clusters because of  (a) their small size  (b) the fewer number of atoms in them (c) surface area is smaller (d) their surface is more curved 2. Which of these characteristics would you associate with SEM: A surface imaging tool Maintained under vacuum Provides imaging and compositional data Uses a scanned electron beam All of the above   3. Secondary electrons (SE) are best described as Low energy electrons from the sample surface  High energy electrons from the sample surface  Low energy primary beam electrons  High energy primary beam electrons 4. Atomic force microscopy (AFM) is the most widely used form of scanning probe microscopes for the characterization of nanomaterials since it require: (a) electrically conductive and optically transparent samples (b) neither electrically conductive nor optically transparent samples (c) electrically…

. Oil drilling rigs are used for drilling holes for identification of oil or natural gas sources and for extraction.An oil drilling system can be thought of as a drillinside a straw, which is placed inside a glass. Thestraw assembly represents the drill string, the drillsurrounded by fluid, and the glass represents thevolume, the annulus, around the drill string throughwhich slurry and eventually oil will flow as the drillingprogresses.Assume that we want to control the drill pressure output, Pd (t), with a reference voltage input,Vd (t). A control loop model (Zhao, 2007) consistsof a drill-pressure controller, drill motor subsystem,pulley subsystem, and drill stick subsystem. Theoutput signal of the latter, the drill pressure, Pd (t),is measured using a transducer, which transmits anegative feedback voltage signal, Vb(t), to the drillpressure controller. That signal is compared at theinput of the controller to the reference voltage, Vr(t),Based on the error, e(t) = Vr (t) – Vb(t),…
