Answer whats in the image, please and thank you

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…

Q2: A fiberglass composite consists of a matrix of vinyl ester and reinforcing fibers of E-glass. The volume fraction of E-glass is 30%. The density of the vinyl estiser 0.882 g/cm³, and its modulus of elasticity is 3.6 GPa. The density of E-glass is 2.6 g/cm³, and its modulus of elasticity is 76 GPa. A section of composite 1 cm by 25 cm by 2 m is fabricated with the E-glass fibers running longitudinally in the 2000 mm direction. Determine: (a) The masses of vinyl ester and E-glass fibers. (b) The density of the composite. (c) The composite modulus of elasticity in the longitudinal and the perpendicular directions of the glass fibers. (d) If the tensile strength of the glass fibers, is 1 GPA and the tensile strength of the epoxy matrix is 60 MPa, find the tensile strength of the composite in the longitudinal direction.

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

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

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.

A component of a composite rocket motor ease is subject to a state of stress o_x = 10 MPa, o_y = 5 MPa, o_xy = 2.5 MPa. Use the material data for Carbon/Epoxy (AS4-3501-6) in Table 1.3. Using "principal stress design", compute: a. The optimum fiber orientation.

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.
