Ellipsoid form of a sphere deformed by gravity of its own weight

So I have a sphere of radius $R$, and density $\rho$, elastic modulus $E$ and Poisson ratio $\nu$. With no gravity it is a sphere, but when gravity comes with a direction $(Oz)$ it becomes an ...

Stress v/s Strain in a heated frustum between 2 rigid walls

So consider a situation where we have a frustum b/w 2 walls. We heat it , so it wants to expand but the walls prevent it from doing so. Does the stress in the frustum remain constant or not Say we ...

Poisson ratio and volume change

Consider a rod of 1 m diameter and 2 m length. The Poisson's ratio of the material is 0.5. Assume the rod is stretched to 2.5 m length. Now longitudinal strain is 0.5/2 = 0.25 lateral strain = ...
