A plastic ball is inflated enough to produce tangential stresses.

In summary, the conversation discusses finding the thickness of a plastic ball after inflation, given the knowns of stress X and Y, radial thickness before inflation, and the tensile and shear moduli of elasticity. It is suggested that instead of just giving the answer, it is better to guide someone in setting up the necessary equations to solve the problem.

A plastic ball is inflated enough to produce tangential stresses. Stress X = Stress Y = 2000Kpa
The radial thickness of the material is 1.2mm brfore inflation. Find the thickness after inflation if the tensile modulus of elasticity is 3.4Gpa and the shear modulus is 1.4Gpa.

this looks very much like a homework problem, so chance are you won't be getting the answer- "teach a man to fish"

list your knowns and unknowns
what equations are relevant?
can you set up a system of as many equations as there are unknowns?

Thanks Jehan, I have moved my post to the homework section.
 

FAQ: A plastic ball is inflated enough to produce tangential stresses.

What is a plastic ball?

A plastic ball is a spherical object made of plastic material that is typically used for recreational purposes, such as sports or games.

How is a plastic ball inflated?

A plastic ball is inflated by using a pump or by blowing air into it through a valve. As the ball is filled with air, it expands and becomes larger in size.

What are tangential stresses?

Tangential stresses refer to the forces that act on the surface of an object in a direction parallel to its surface. In the case of a plastic ball, these are the forces that are exerted on the surface of the ball as it is inflated.

Why is it important for a plastic ball to have tangential stresses?

Tangential stresses are important for a plastic ball because they help maintain the ball's shape and prevent it from deforming or bursting. Without these stresses, the ball would not be able to withstand the pressure of the air inside it and would collapse.

How much should a plastic ball be inflated to produce tangential stresses?

The amount of inflation needed to produce tangential stresses in a plastic ball depends on the size and material of the ball. It is important to follow the manufacturer's recommendations for proper inflation to ensure the ball is not over or under-inflated, which can affect its performance and durability.
