Explain briefly how these decals stay on the window

A metal term used to indicate that two or more layers of plastics (or metals) are pressed together under pressure is ______.

Describe the limiting angle of repose. Provide equations and examples to support your point

QUESTION 1 Ribs are a feature in plastic injection molded parts. They are thin extensions that run perpendicular from a wall or plane. They are commonly used to provide additional support and strength to a part as shown in Figure Q1. Recommend the guideline to design the ribs for plastic injection molded parts. Figure Q1: Plastic part with ribs

Answer whats in the image, please and thank you

In a well constructed paragraph define the material requirements for a single-use (disposable) water bottle.

Compression molding is a manufacturing process in which the molding material is preheated then placed in an open mold cavity where the compressive action of the punch forces the polymer into the desired shape as shown in the figure below. Based on your understanding of the behavior of polymers, which of the statements below regarding compression molding of polymers are accurate? Punch Cavity C. -Upper mold half Charge 41 (1) -Lower mold half Knock-out pin V, F |x.F (2) and (3) Molded part a. Lower operating temperatures are more desirable as they reduce viscosity making it easier to fill the cavity b. This process can only be used for thermosets as they can thermally cure from monomer state This process can be used for both thermosets and thermoplastics as they can both be thermally shaped d. This process is suitable for rubber, PVC and polymethyl methacrylate

I want to explain how to count j1 (half joints) and j2 (full joints) in the degree of freedom and when i increase a number or decrease a number when counting like this drawing. I want all the rules related to counting the point with an explanation (mechanical system) plss

As the lead engineer for a LPG storage project, you are overseeing the design of pressure vesselssuch as those shown below. Identify which test (or tests) is mostsuitable to pick a material and thickness for the spherical shell of the pressure vessel. Why these are the relevant tests. Explain what information these tests provide and why it is important to determining material and thickness.

Which of the following are reasons why injection molding of thermosets is more difficult than injection molding of thermoplastics (two best answers): O allowances must be made for cross-linking of thermosets O barrel temperatures must be hotter for thermosets O cycle times are longer because of curing thermosets are denser O two injection units are required
