The velocity of light changes when it passes through a medium of a different refractive index. So let's suppose the light is traveling through a vacuum at a velocity c and then passes through a glass wall. Its velocity decreases while traveling through it but then speeds back up to c after...

Here is what I understand so far about x-ray energy transitions within an atom: The shells are divided up from lowest to highest as K, L, M, N, O, and so on. The X-ray associated with an electron dropping to a K shell is called K radiation. If the electron drops dropped from a shell directly...

Thank you for the reply phyzguy. What I still don't understand is what continues to generate the magnetic field when a majority of the electrons and protons are squeezed into neutrons.

The sources I've looked at claim the magnetic field is present because there are still some electrons in the neutron star. Here is how I understand their reasoning: a star's radius significantly decreases when it collapses into a neutron star, ultimately decreasing its moment of inertia. In...

You are right, JRMichler; cracks form at the locations of maximum stress. To the best of my knowledge, the wheel was not subject to cornering forces. I unfortunately don't have any background in FEA; however, simple calculations should be enough to prove that stress concentrations occur where...

I am currently performing failure analysis on an A356 Aluminum alloy wheel subjected to rotational loading, with a maximum load of 650 kgf and a torque of 4600 Nm. Cracks formed in the wheel after 1.3*10^6 rotations. My job is to perform a stress analysis to determine the regions of maximum...
