it is to be designed for 4 inches wide x 5 3/4 inches long x 1 inch thick desktop computer hard drives and to handle laptop computer hard drives that are 2 3/4 inches wide x 4 inches long and vary from 5/16 inches thick to 11/16 inches thick.the majority of these drives are 5/16 inches thick.

the magazine must hold a minimum of 12 drives.

i am required to come up with a production magazine system that easily adapts to the existing machine and should be simple and safe to use.not requiring special training to install,load and use.

suggestions and ideas please]]> Mon, 16 Jan 2012 14:53:51 +0000 http://mechanical-engineering.in/forum/topic/9595-how-to-design-a-feed-magazinee/ Store boxes on their large side with gravity. http://mechanical-engineering.in/forum/topic/9592-store-boxes-on-their-large-side-with-gravity/ I have to DROP boxes from the top of that tube. they will drop with gravty. boxes are light catoon medicine boxes.

Of course, even I drop then as their wide side looks below, because of friction, small hits to the borders
of the storage tubes, their position will change while they drop.

What I need is a mechanical design of tube, maybe with some shapes or planes in it, so,
as boxes drop about 2 meters, at the bottom, this design will align boxes an in the picture.
they should be stored vertically not horizontally.

any idea will be helpful my friends. thanks.

I have two aluminium detail with flat surfaces, that I want to connect one to another. (let's say around 2-3 cm2). One of them is on the top and it fixed to my setup. Another one is on the bottom. There will be a distance between them around 3-5 mm for PCB, that will be connected to the bottom part.

I want to have an opportunity to easily disconnect the bottom part with pcb. I mean no screws and nuts.
I am thinking about some spring - like in a pen - click - and it fixed, another click and it unfixed. Or some nut with no thread, but with a button to fix/unfix it.

Es = 200 GPa; Eb= 80 GPa


2. a steel bolt of 16 mm dia passes centrally through a copper tube of internal dia 20 mm and external dia 30 mm. the length of the whole assembly is 500 mm. after tight fitting of the assembly, the nut is overtightened by quarter of a turn. what are the stresses induced in the nut and the bolt if pitch of nut is 2mm.

Happy to see this forum.

I am trying to model a mems resonator using comsol software, and the core of the resonator is a Piezoelectric rectangular plate clamped at the center on either sides (center of the length). For our resonator to work, this structure must vibrate in contour or in plane mode with little or no out of plane deformation. What are the conditions for this to happen?? Also, can anyone please tell me how to calculate the vibrational fundamental modes or eigenfrequency for this structure?

http://morenojoseali.blogspot.com/2010/05/aluminum-nitride-contour-mode-vibrating.html

The image is presented on that link (the rectangle only). I am also interested in the length extensional mode (deformation along the length) and woul be very grateful if someone could explain it or direct me to some place with answers. Being an electronics engineer, it is proving to be a lot to swallow. Would appreciate any help.

Till later,

First of all, I'm not an engineer so please excuse any incorrect terminology. :)

I am looking for help with a patent pending accessory that mounts onto a pistol. I am located in FL, USA and would love to either find someone in the state (preferred) or online who has experience with firearms and the forces the mount would be subjected to. Specific knowledge of the 1911 would be extraordinarily helpful!

I have functioning prototypes, but am running into 3 issues:

1) Durability issue with higher round count (either caused by forces involved, improper dimensions, or ?)
2) Fit issues with wide variance in tolerances by manufacturer
3) Mounting/Locking device or solution that will hold up under use and the forces involved, as well as allow for easy removal of the mount.

Any help or direction would be greatly appreciated!

Thanks!

i will b interviewed for the post of management trainee PRODUCTION.
the following are the questions i think will feature throughout the interview:
1.why such a meagre GPA(2.9/4)?

2.i was part of a final year project team who had to design and fabricate a HHO system to be installed into the car and investigate the effects on the fuel consumption.though it wasnt my idea but that it was thrown down at me by my group mates who did not work on it,neither planning nor its execution.i did all the experimentations at my home..bought material from the market..tested all configurations and concepts of an HHO cell.finally decided with the dry-cell but fell deadly short of time.had to submit and demonstrate it a day after being though the final exams.so as soon as i got over with the exams i went up to a car mechanic...he altered the carburetor jet of a gasoline generator and we observed the proposed decrease in fuel consumption by using a 50 ml syringe full of petrol and a stop watch..i was glad i succeeded.and then again i managed all this single handedly..and submitted the report to the examiner despite the disappointment of not being able to install this thing in the car and run it...

how should i express all this in a more formal way to the interviewer..he would be most interested in knowing WHAT skill has been demonstrated here?..and how can i be helpful to them.
3.as u know this is an automobile and motorcycle assembling company.and as i am being interviwed for the post of production engineer,what possible TECHNICAL questions should i expect?how much related to internal combustion engines,manufacturing processes,machines,thermodynamics, ?
please elucidate

Well I'm a third year mechanical engineering student of the University of Kerala! In our 5th semester, we've got Theory of Machines and in that subject we've learned about Steering Mechanism in Automobiles.

As per what we have learned, for a front steering vehicle, the wheels are mounted on a stub axle which is pin jointed to the front axle. As the the vehicle turns on the road the front wheels should make a concentric circle with their centers at the Instantaneous centers which lies in line with the rear axle!

Here's the image showing what is said above.
