I designed two geometries (one for beam/line reinforcements and other second for a solid block shown below) in Ansys workbench spaceclaim for static structural analysis.
In Ansys workbench Mechanical, I got a weird mesh for the reinforcements which I modelled as beam in Spaceclaim (shown...

So you need to find the voltage across node D while the capacitor is charging, so it is going to be related to the voltage of the capacitor, so a function of time, so you need to come up with the equation for Vc(t), which I...
Homework Statement
An organ pipe with one end open and the other closed is operating at one of its resonant frequencies. The open and closed ends are respectively:
A. pressure node, pressure node
B. pressure node, displacement node
C. displacement antinode, pressure node
D. displacement node...
What causes there to be a node at a closed end of an air column and an antinode at the open end of a air column? Why doesn't it change as the wave oscillates?

Dear Everyone,
Could anyone explain why we count only the number of radial nodes between the subshells that have the same orbital angular momentum l ?
For example, 3p-orbitals have 1 radial node that exists between the 3p- and 2p-orbitals.
Shouldn't be there additional radial nodes that exist...
I do not understand why standing sound waves can be formed in a one-side or two-side open tube. Consider a one-side open tube.
In particular how does the reflection of the wave at the open end occur? I found the following explanation.
I do not get why the pressure at the open end cannot vary...
In a radial node of an orbital, say of 3px orbital, is the probablity for finding the 3px electron there is 0 but an electron of another orbital, say 2px, can be found there, OR the chance of finding electron of any orbital in a node of a certain orbital is 0?
Hello,
I have a typical 1D advection problem where a cold fluid flows over a flat plate. I did an energy balance to include conduction, convection and friction loss and I got the PDE's for the fluid and the solid. I used finite differences to solve the system as T(x, t) for both fluid and...

a. FBD:
The force goes through the nodes, and the sum of the forces must be 0 because the nodes are massless. Therefore, kx_1 = x(t)
So x_1(t) = x(t)/k
b. FBD:
For this system, the parallel...
