What are some lightweight and durable materials?
Aluminium and Titanium Extruded polystyrene is about as strong as unalloyed aluminium, but much more flexible and much lighter.
What happens when natural frequency is at zero?
That is a rigid body mode of high mass that has no oscillation.
How do you define the rigid link fluid link and flexible link The application for these in theory of machines?
1. Rigid link. A rigid link is one which does not undergo any deformation while transmitting motion. Strictly speaking, rigid links do not exist. However, as the deformation of a connecting rod, crank etc. of a reciprocating steam engine is not appreciable, they can be considered as rigid links. 2. Flexible link. A flexible link is one which is partly deformed in a manner not to affect the transmission of motion. For example, belts, ropes, chains and wires are flexible links and transmit tensile forces only. 3. Fluid link. A fluid link is one which is formed by having a fluid in a receptacle and the motion is transmitted through the fluid by pressure or compression only, as in the case of hydraulic presses, jacks and brakes.

What element makes up polystyrene?
Polystyrene is a synthetic polymer made from the monomer styrene. This monomer is a liquid petrochemical and can be rigid or foam.
How do you spell pollistiring?
The likely word is polystyrene (a rigid plastic, also the basis for styrofoam).
Is styrofoam the same as polystyrene?
They are made from the same polymer, polystyrene. Usually polystyrene is clear, hard and rigid, for example in CD cases. However, styrofoam is created by blowing air through liquid polystyrene. The bubbles are locked in the polystyrene as it solidifies, giving the syrofoam used in packaging and cups. The reason it is compressible is because the air is compressed, rather than the hard, rigid polystyrene itself.
What is the difference between rigid polystyrene plastic and expanded polystyrene?
Rigid polystyrene plastic is a closed cell of light weight, rigid & foam plastic that is derived from petroleum and natural gas by products. It is hard plastic in one word. This is used to make plastic containers and insulators. On the other hand, expanded polystyrene is derived by expanding the regular foam molecules by 50 times their volume using a blowing agent (pentane gas). This is used to make packaging materials.

What are the differences between expanded polystyrene and polystyrene, and how do these differences impact their respective uses and applications?
Expanded polystyrene (EPS) is a lightweight, rigid foam material made by expanding polystyrene beads. It is commonly used for insulation, packaging, and construction due to its excellent thermal insulation properties and shock-absorbing capabilities. Polystyrene, on the other hand, is a solid plastic material that is more rigid and dense than EPS. It is often used in food packaging, disposable cups, and other products requiring a solid plastic material. The differences in density and structure between EPS and polystyrene impact their uses and applications. EPS is preferred for applications requiring lightweight insulation and cushioning, while polystyrene is better suited for products that need a more solid and rigid material.
Why is polystyrene brittle?
Unfilled polystyrene is also known as crystal polystyrene (PS) or general purpose polystyrene (GPPS). However, since crystal polystyrene is brittle, other polymers are added to polystyrene to improve its strength, and copolymers are formed as a result. One such copolymer is high impact polystyrene (HIPS), which is produced by adding polybutadiene rubber to polystyrene during the polymerization process. HIPS is tougher and has a greater impact strength than unfilled polystyrene. There are different types of polystyrene. Extruded polystyrene (XPS) is one form of the polymer that has high tensile strength, with good elasticity. It is commonly known as Styrofoam™. The other common form of polystyrene is expanded polystyrene (EPS). Both EPS and XPS are made from similar materials but there are difference between the two. XPS has a higher density as compared to EPS, due to the absence of air passages between its cells. The higher density makes XPS more rigid and strong. Also, XPS is waterproof and is an effective thermal insulator. Read more in the related link.
Why is the glass transition temperature of polystyrene greater than of polypropylene?
Higher the glass transition temperature of the polystyrene can be attributed to the fact that sterically rigid bulky aromatic moieties like benzene in the styrene compared to that of aliphatic polypropylene
What can you do with polystyrene?
Polystyrene can be used in various industries like Polystyrene Packaging, Construction, Display, Exhibition, Signs, and all areas of the foam industry. Various different items can be produced from polystyrene. For a complete range and details about products please visit: http://www.polystyrene.uk.com/
What are the uses of polystrene?
Polystyrene in its foamed state is often used as an insulating material, or in packaging to protect goods in transit. In its rigid state, it can be used to manufacture many diverse goods.
Is polystyrene cheaper than foam in new zealand?
Polystyrene is a plastic polymer, and along with many polymers may be made into a foam. But it has a high fire hazard because of the entrained air. Indeed it is commonly used in that form in furniture, cars, packaging, refrigerators, and so on. A quite good thermal insulator. The solid polystyrene is widely used for rigid consumer products, and is a fair electrical insulator
