Does the raw egg have to come out of the black box as an unsmashed egg?

Bump, I could really use some help on my last post, this is really holding me up at work and I have been trying to make sense of those equations for awhile, anyone have any tips?

I have a slightly different question but it is along the same lines. Assuming you have only 4 tie downs such as shown below, how do they come up with the solution below? I have tried playing around with it but I have only 3 equations and 4 unknows, the equations are \SigmaFz: T1v + T2v + T3v...

I came across this problem, http://www.rsip.lsu.edu/csmlab/courses/1undergr/ce3400/lectures/lect_09/sld026.htm and if I proceed in a similar manner I can determine the forces in each of the straps. Is there a fundamental assumption which is wrong when applying the above solution to my...

Sorry I didn't make that clear in my previous problem with the beam and four vertical straps, assume I know Young's Modulus for the straps, take them as nylon with E = 4 GPa. I am still fairly stumped by the boundary conditions where each of the straps connects to the block. If I make the...

Bump. Sorry to resurrect this thread but I really could use some help, does anyone know of any sample problems similar to this one? I have tried searching PF fairly extensively as well as the web. Any help is much appreciated

Okay so I was working on something else for awhile but I have been reassigned to this. I guess my main problem is determining boundary conditions. I scanned a copy of a problem I made up which essentially incompasses the part of the problem above which I am having difficulties with. I have...

Sorry the bird's eye view is a bit misleading, the straps are at an angle to the vertical, longitudinal and lateral axes, but in the bird's eye view I just showed the longitudinal component for simplicity. The straps are anchored on the edges. So I would need to solve this be determining the...

I’m pretty stumped by this, maybe I am just making a stupid mistake but if somebody could clarify it would be much appreciated. The system I am looking at is something like the one below, with 4 straps of each side. Their locations relative to the center of gravity along the lateral direction...

Are there any good ways of pinpointing what part of the structure is transmitting the vibrations resulting is the noise? I have been told the engine and other machinery are mounted of shock absorbers, however I haven't seen this first hand.

I am responsible for investigating excessive noise problems in the cabin of an aluminum fireboat. I have no idea if the problems are with structure borne noise or airborne noise, so here is what I was thinking about doing, please let me know if there are any problems with this method. I was...

This problem tests basic ability to read a P vs. T phase diagram. Since the state of the substance depends on both temperature and pressure, think about fixing your temperature and then seeing what happens as you alter pressure.

Just to update this, I have done some searching on the forum about the use of FEM. Would the best course of action to solving this be to model the part in a program like ANSYS? I know the distributed load and the part dimensions (except for the thickness, this is what I am trying to calculate)...

For a summer job I am employed to look into the use of composite paneling in place of sheet aluminum with stiffeners. I am suppose to find the required thickness of composite wall paneling in order to make a structure such as the one attached. Obviously it will depending on the material...

Oops sorry, the aluminum currently used is 5052, mill finished. If there are any other details I am forgetting please let me know
