PROBLEM: VIE-6 BOOK: ENGINEERING THERMOFLUIDS, M. MASSOUD (You can answer my question even if it's rough or with a lot of assumptions, I just need an overview on how to solve this kind of problem for my exams and knowledge, Thanks.)

16) Composite material with plastic as a matrix material can be used as biomaterials Select one: True False

Help!

You have been asked to help a world famous sculpture artist with a new project. Part of the design calls for an array of long, slender cantilever beams extending from the side of a building. The artist has a fixed length in mind for each beam, and r esthetic purposes, she wants the beams to be square cross sections (b × b) that are as thin as Q9. possible (smallest possible b). Each beam has a limit on the end deflection, DELTA (8), and also it should not break under load. Identify the constraints for this design case. I. It should not break under load. II. Smallest thickness, b. III. Fixed length of beam. IV. Deflection should not exceed 8 А. I and III B. I and II C. III and IV D. I and IV |

What is the difference between thermoplastics and thermosets?   A)Thermosets are cross-linked, thermoplastics are linear polymers. B)There is no significant difference. C)Thermoplastics cannot be melted, while thermosets can be. D)Thermoplastics are more elastic then thermosets.

As a technologist, you are given the following design task: In a manufacturing environment, the final product needs to be packaged and sealed. After the product is placed inside the plastic bag, a hot pressing die is to be used to seal the plastic bag by application of heat and pressure. The operation should be as follow: By pressing a pushbutton switch, the heating rail is advanced and the packaging material is heated along the adhesive strip. After the adhesion pressure has been reached, the heating rail must return to its start position The design specification includes the following: Pressure dependent reversal with monitoring of the end position by means of magnetic proximity switches. Include safety measures, a green light to show when the system is ready, a red light when system is in operation, a warning sound when the heating rail is moving. 1. Draw your pneumatic circuit design for this application. 2. Draw the electric circuit diagram for your design.

The 3d printing approach shown below is fused deposition modelling (FDM), where feedstock polymer is fed into the heated printer nozzle and deposited onto the platform to form the final object in the desired geometry. Which of the polymers below are suitable for this process and what nozzle temperature should be used for that material? (This question has more than one correct answer) Material spool Heater element Object/Model * Nozzle Build platform
