This mechanism move the soil through steel plates attached to chain and gears.The mechanism is unstable since there will be high Fx and Fy of hydrualic cylinder,Any other way to stable mechanism ? or any other design ideas please Thank you

I am currently designing an alternative to normal acoustic drum lugs and I need to find the forces that are felt by the tuning rods of a drum for the engineering background to my design. I have been able to use the 2D wave equation assuming uniform tension on the membrane and found values of the...

I have converted given pressures from bar gauge to bar abs Inlet pressure = 20 - 1.013 = 21.013 bar abs Outlet pressure = 6 + 1.013 = 7.013 bar abs therefore pressure drop (x) x = {p_1 -p_2 \over p_1 } = {21.013 - 7.013 \over 21.013} = 0.6662542236 bar abs Comparing to the chart values for...

I've been working on a tool in a browser for engineering (particularly civil engineering) design. By design, I just mean finding values (maybe the cross-section or material of a beam) which satisfies constraints. You would define constraints, possibly have something to minimize or maximize (like...

Can anyone recommend a place to find case studies in electronics design? I am looking for concrete examples of the engineering process from requirements definition through PCB layout. As a physicist who designs instrumentation I would like to improve my improve my design process and employ more...

Hello everyone! Summer is coming and instead of buying a $200-$400 air conditioner, I'd figure I could try a DIY version. I came up with a schematic (attached below) and how I think it would work. I feel like I'm missing something blatantly obvious that will make it not feasible. Wondering if...

I'm working on a question which asks to determine the deflection, curvature, forces and moments of a simply supported beam with a distributed load. diagram shown in here http://imgur.com/a/wpI4kInitially, I've done the calculation with 1 plane beam element with 2 nodes. At L = 0 and L = 3. But...

Hi, is there a website that gives the detailed design and technology of various devices/equipment and/or manufacturing processes? howstuffworks, popsci and other similar sites have very trivial and basic information. some typical examples i am trying to find are.. camera, fridge...

For my physics class, my group is assigned to do a following project. Design and construct a machine that will safely transport a set of eggs from a bottom corner of a 1x1x1 meter virtual cube to the diagonally opposite upper corner (e.g. bottom-front-left to top-back-right) using at least...

Hey. I am currently in an engineering class designing a truss bridge and had a couple questions. (Note all truss members are considered to be two-force members) 1) Suppose the truss is symmetric and a force is applied through the middle of it. Is it normal in industry for any individual...

Hi guys. I just want to know how Modeling (Mathematical modeling), simulation and Engineering Design are related. Your views are welcome. Any references and links would be appreciated. I just want to know more about the Design Process and how different processes and techniques are used for...

Need help with Engineering design project! For our low level engineering design class we have a semester long project. I am going to explain the project as clearly as possible. It is a design competition in which we have to build a vehicle. This vehicle must utilize the potential energy of...

hello i am new to this forum..i have been set a problem whereby i am asked to design a machine to remove radioactive fuel elements which are contained in cylinders. i am asked to only look at the mechanical aspects (lifting device) of the design. Density and measurements were given and mass of...

Where can one get a e-Documents/eBooks that will provide for the basic concepts, Technical guidelines to go about choosing Hobby Telescopes & general purpose Binoculars (construct differentiators and features that conceptually approach professional quality) but stays within the boundary...

Hi, I need a little help on figuring out what size square tubing and thickness I need to make a basic lift for taking the body of a car on and off of a frame. I have included a small drawing of what I am trying to build. I am going to need to support a maximum of 1000 pounds. All off the...

For my bioengineering class, my project group and I were presented with the following problem for a design report: There is a nuclear reactor which uses a pipe system for cooling. This pipe system is comprised of 2 units with 6 pipes each. Each of the pipes contain a pump, and each of them...

Hi, I was wondering if anyone here knows (and could tell me) how to put together a front end engineering design. I've been asked to create one, have no idea what it is and so far google has been no help! Thanks

I'm currently taking a class on engineering communications. Don't worry this isn't asking for numerical homework help but rather to brainstorm physics topics that can be demonstrated and presented in a 15 minute interval. Past projects extended by electrogravity, where they put a lot of...
