Physical Properties Of Rubber Ball

In this lesson students will explore the physical properties of a variety of balls and how they bounce i e their bounciness or elasticity the point of the activity is not necessarily to have students arrive at a precise explanation for the phenomena they are investigating but to provide students with the following experiences.

Physical properties of rubber ball.

The inherent physical characteristics of elastomers can be modified through compounding. The marble will bounce the least high. However the knowledge of rubber s physical properties and their measurement is critical for compound selection. In this article the molecular origins for this unique behaviour will be addressed.

The dry content refers to the content of dry rubber in the latex. All rubberlike materials are polymers which are high molecular weight compounds consisting of long chains of one or more types of molecules such as monomers. Rubber balls are used in fda uses for games and sports for light load bearing applications. For elliminating chatter or vibration in cabinetry rubber balls are used.

Judy scotchmoor and lisa white. 605 author pidegree gloves publish time. Galsports exercise ball 45cm 75cm anti burst yoga ball chair with quick pump stability fitness ball for birthing core strength training physical therapy 4 6 out of 5 stars 1 205 17 99 17. The rubber materials selected by designers and technical buyers should meet all their application requirements.

If the cloth cover wears down to say 2 mm thickness the ball will become softer. There are rubber balls used in the flow control and flowmeter applications in the pharmaceutical food and chemical processing industries. When all three balls are dropped from the same height the rubber ball will bounce the highest because it has the greatest elasticity. Repeat steps 11 and 12 for the ping pong ball.

The rubber is about 3 mm thick and the cover is also about 3 mm thick. Properties of rubber balls. On average the rubber bouncy ball will bounce the highest followed by the ping pong ball. Natural latex physical properties.

Polybutadiene butadiene rubber br is a synthetic rubber polybutadiene rubber is a polymer formed from the polymerization of the monomer 1 3 butadiene polybutadiene has a high resistance to wear and is used especially in the manufacture of tires which consumes about 70 of the production another 25 is used as an additive to improve the toughness impact resistance of plastics such as. Rubbers are a fascinating class of materials because several of their unique properties have no parallel in the nonpolymeric material world. The total solid content refers to the content of. A used ball is generally softer than a new ball since ball stiffness depends on the wall thickness and the amount of air inside the ball.
