MMET 206 Lab Report No 7

Answer whats in the image, please and thank you

Can someone assist me please? Thanks.

For an application of high strength components including gears cams and rollers the desired properties in a plastic would be high tensile and impact strength, stability at high temperature, and machine ability. Potential materials which are suitable for these applications are nylon phenolics, TFE filled acetals, PET, and poly carbonate. True or false.

How may acoustic designers alter the design of a room, which was previously used for music performances, into a room now to be used for spoken word performances? Use annotated diagrams for your response. For the answer please include the different materials used in the different settings. I.e what designs and materials will be used for a music room vs a speech room.

I need assistance designing three structural models on Fusion 360 (bamboo-inspired, bone-inspired, and a control cylinder) for a mechanics project. These models will be tested under compression to compare their load-bearing capacity, energy absorption, and failure modes. Here are the specific details and requirements for each design: General Requirements: External Dimensions: All models must have the same outer dimensions: height = 15 cm, diameter = 5 cm. Material Volume: Ensure each design uses approximately the same material volume (e.g., relative density = 30% of the total volume). If you have any other ideas on how to ensure the test is fair between all 3 samples please note it! File Format: Provide the designs as STL files compatible with 3D printing or a step-by-step process.  Design Specifications: 1. Control Cylinder: A simple hollow cylinder with: Wall Thickness: 2 mm. Inner Diameter: 4.6 cm (to maintain the outer diameter and wall thickness). No additional…

Kindly solve it completely by hand if possible.

can you help me answer this question and explain the steps you took to get to the answer i  am stuck between B and D as the answer

d) A number of [0]s and [0,90]s CFRP test specimens were made from prepreg material with the following properties: Fibre strength, of = 3250 MPa Fibre modulus, E₁ = 195 GPa Matrix strength, m = 35 MPa Matrix modulus, Em = 3.8 GPa Volume fraction of fibres, Vf = 0.65 Calculate the tensile strength, oc, and the tensile modulus, Ec, in the 0° and 90° directions, using the simple "rule of mixtures" approach for both the [0]s and [0,90]s specimens.

In your summer internship, you are tasked with measuring the ultimate tensile strength of a material to determine if it meets your company’s (Superior Super Ships Inc) specification. Your boss is worried that the new low-cost supplier, Shoddy Alloys Inc, may not be reliable but it is the only way to source on-time the SS304 needed to make finishings for Jeff Bezos’ new yacht, the Black Pearl. You collect several load versus displacement curves, as illustrated below. The initial diameter of the round gauge section is 0.25 in. You also collect the instantaneous diameter of the specimen during the test using a laser. Using the provided data, calculate what is the ultimate tensile strength measured in this test?

Please do not give a typedout answer. They are hard to follow/read. Please write it out, draw a FBD if needed, Thank you

Question 1 A composite material consists of 40% parallel carbon fibres with a Young’s modulus of 405 GPa in a matrix of epoxy resin with a Young’s modulus of 2.5 GPa. Calculate the Young’s modulus of the composite in the parallel and in the perpendicular directions of the fibres. Use the graphical method seen in class to show the possible value of the overall young modulus of your composite material.

A polymer has creep behaviour that can be represented as a power law equation: e = 0 (Jo + Jit") where J, is 0.5 GPa1, J1 is 0.45 GPa's 0.3 and n is 0.3 (with t in seconds). A component of this material has the following applied stress history: There is no stress before t = 0 A positive (tensile) stress of 8 MPa is applied from t = 0 for 4 hours From t = 4 hours to 6 hours, the stress is compressive stress of 2 MPa The stress is then removed. What will the strain in the material be at t = 9 hours? Enter your value as a number to 4 decimal places. You have a 2% error margin with this.

Please solve accurate and exact answers sir please!! (it must be typed not handwritten)  Thanks!!
