Calculating deflection of a cantilever beam using Young's modulus
I have looked at a lot of deflection questions on here and I didn't see anything that quite matched what I needed to know.
I am working through some curriculum for students and I am working through ...

How can I anchor a rubber sheet that will be stretched?
I am designing a cylindrical container that will be filled with water. One end of the container will be solid with flow port and the other end will be a 3mm rubber sheet. I want to oscillate the ...

Why are Lamé parameters different in two dimensions?
The Wikipedia article has a completely separate table for Lamé parameter conversions in the 2D case. Philosophically, why is there even a different table for 2D if these parameters are meant to ...

Strain As A Function of Deflection of a Hollow Cylinder
I should think that there would be a direct correlation of strain to deflection of a hollow thin-walled cylinder, but I've seen nothing as of yet. I must be missing something. For example, let's say I ...

Is there a rubber material with an elastic modulus lower than 1 MPa?
I'm looking for an elastic material (e.g., a rubber), whose tangential elastic modulus E is lower than 1 MPa (0.5 MPa would be enough). Anyone has an idea of which kind of rubber could fit this ...

What is the difference between Hooke's Law and Young's Modulus?
In the elastic region where stress is proportional to strain up to elastic limit which is we call Young's Modulus (E). My question is if that is E, then what is Hooke's Law (K=F/x spring stiffness). I ...

How to measure compression modulus of a paper-thin elastic sheet
Is there anyway to measure the young's modulus with a compressive force on a paper thin elastic sheet (made out of a rubbery-fabric material)? I wish to compress the sheet in an orientation that ...

Difference between Stiffness (K) and Modulus of Elasticity (E)?
Stiffness (F=Kx) is the extent to which an object resists deformation in response to an applied force. Elastic Modulus (E=Stress/Strain) is a quantity that measures an object or substance's resistance ...

What is the physical reasoning behind metal becoming stronger and harder if heat treated?
I was wondering that if a proper process of heat treatment (heating to a temperature above upper critical temperature, then soaking and then quenching) is applied to a metal like steel, then what ...

Is there any difference between an-elastic and visco-elastic materials?
Most of the sources that I had read about either talks about anelasticity or viscoelasticity, they don't compare both. From what I have read so far ,both anelastic and viscoelastic materials are the ...

Does perfectly elastic and perfectly plastic material make any sense?
I have been reading about the elasticity of materials and most often in engineering there is always some ideal concepts which are the extreme cases. So is there any particular definition to what is a ...
