    I find it hard to choose a company to work for or to do an internship at. I want to make the world a better place with my engineering skills but it is not easy to find the right place for doing so. Of course there are the big players but I would like to have, for example, a map with all, or at least a lot of enviromental aware companys in different fields of engineering. I believe it would be a great thing to have an overview, of companys that try to make the world better and healthier, and not being all about money.Does anyone know of a information pool, where i can find access to that kind of data?I would greatly appreciate any tips and clues you can give me about that topic!Is your company the place to be maybe?Thank you all,cheers,Ruben

    Hello, I have derived some relation between driving torque and slider force "just for fun" (see attachement). Therefore it should be checked. Any inertial foces are neglected (you wrote, it is a slow motion) I have used a simplified transfer function from old lecture notes. More accuracy can be achieved deriving this function by means provided by DrD. At the dead points the required torque becomes zero. This can be explained as follows: At the instant, when the crank joint passes through dead point, it moves laterally with respect to the connecting rod, whereas the slider does not move. The rod just rotates about the joint of the slider. Thus no counter force exists for the crank at this instant. Regards Alban CrankSliderMechanismTorque.pdf
  33. Perilun
    That is also my opinion. The problem is, that the rotation speed of the motor will be very low. Thatswhy i need to calculate it, to know which moment i need to move the system.
  34. Alban Kronenberger
    Hello, the dead points of a crank slider mechanism are reached if all joints are in line. Acc. to my opinion, dead points will be critical only, if the mechanism is driven by the slider (piston). If it rests in a dead point, it will need some lateral force at the connecting rod to "come out", which an ideal slider can not deliver. In your case it seems, that the mechanism is driven through the crank by an electric motor, which is able to create some lateral force at the dead points. The lateral direction is identical to the tangential direction, in which the joint of the crank shaft is moving at the dead points. Regards Alban

  36. Perilun
    Thank you for your fast answer and the book! I know this kinematik equations. I do not understand how to calculate if there are problems in dead points, for example the system will stop and not move in these points?
  37. DrD
    You can find a lot about this and many other mechanisms in the newly released textbook Mechanics of Machines, 2nd ed. Please download a copy and encourage your friends to do the same; it is offered without charge to everyone. DrD MoM2DraftMar2019r1-compressed.pdf
  38. Perilun
    Hello, at the moment i am trying to design a crank slider mechanism. This mechanism should be driven with the help of an e-motor. Through this rotation a slider should move. Unfortunately i have some problems, because i can not find any good books about the calculation of these mechanisms. For example i do not understand how can i calculate the system to avoid it to come to a stand at the dead points? Can someone help? Thank you in advance!

    So, there is this pipe, wich has 6 outlets, and the problem is, all the 6 products that comes out, is in different shapes. The goal is, to make the shapes all equal. The product is an ice cream bonbon, so it is in a half sphere like shape, the cream has higher viscosity than water, and there are gas bubbles in it. It has to keep its soft and tender texture. The products come out 6 at a time in a row, on metal plates, and then they go to the cooling tunnel. What could cause the problem, and how could be solved, by changing the pipe outlet device, but keeping the structure, so it still comes out 6 in a row? Building in a reducer? Buffer tank, maybe? The inside diameter is around 10-12 mm. I cant upload picture of the device, so here is a layout: And there is an adjustable pressure equalizer thingy in the back of each outlet pipe: I hope its enough information, if need anything else, ask it. I dont understand fluid dynamics enough, I hope someone could help, I am just interested in the idea, not the accurate solution. Thanks

    I'm(22m) am a 3rd year product design engineering student and we've been tasked with bringing a previous designed concept to the point that you have a complete idea of what it would be produced (basically how will it be manufactured, to what scale, who is sold to, how is it packaged etc). I'm getting held back by the maufacture The photo is my previously designed concept: the idea is you drop metal ball down the slide (a conical spiral) and the ball is collected in the tray at the bottom. Its designed to be able to be placed in the corner of the average office desk (e.g. its a office desk marble run). My question is: what process will I use to manufacture the spiral slide and what can I make it out of? Ideally, I'd like to have it to have a fairly clean aesthetic look (e.g not just bend some PVC pipe) as its going to marketed as a nice ornament to have on your desk. I'm not too worried about the supports or the base but creating the conical spiral slide shape is giving me a lot of grief. I know I can 3D print the shape (as I have a model) but I don't think this is the most cost effective strategy and I have to produce a document of how much it will cost etc. Should I adapt the design slightly to make it easier to make? If so how should I do this? Can I CNC mill the shape out of wood or metal? Can I injection mould it out of plastic? Can I use a set up like this ( https://www.youtube.com/watch?v=yigRgG_NIyU ) and just using half a pipe? Could I set up a wood turning rig?
  42. Jennnnnnnnn
    Probably a multitool holder, all applications use the same action the only variable is the tool in use. Most CNC's come with holders for multiple tools. Otherwise if it's a single tool holder they can be interchanged. This should be better explained in the machine brochure or demo video. Hope this helps!

    In the given condition,a multistage centrifugal pump designed for a suction lift of 25 mtrs or more may be explored.I am not aware whether a centrifugal pump is being manufactured having above specification. Alternatively,suitability of a booster pump down the suction line of the existing pump may be explored.. If condition permits,a submersible pump will be a better option,

    Hello, I have an FRP composite with PMMA flakes, fiberglass roving cut and polyester resin. Now the samples are circular shapes with 160 mm in diameter. Which will be the appropriate dimensions of a sample in order to test them for bending, compression, tensile? Thank you!

    Can somebody please help in understanding the difference between pressure compensated variable displacement pump circuit and load sense? Below is my understanding: VD Pressure compensated Pump circuit: You can not control flow rate unless the pressure compensator pressure setting is achieved. After which pump flow can be controlled while pump maintaining that maximum pressure. Load Sense Pump Circuit: Firstly, We can control flow rate by regulating needle valve or proportional valve that is downstream of pump to get required actuator speed without reaching maximum pressure compensator setting. Secondly as the load changes the pump adjusts valve upstream pressure to maintain the flowrate across the valve (which we adjusted before to get required actuator speed). Is my understanding right? Kindly explain in simple terms if you can. Thank you in advance

    Six stroke engine has following work 1:-suction 2:- compression 3:- ignition 4:-exhaust 5:-air suction again 6:-exhaust Actually those last two stroke is added in order to remove burnt gases which are little bit present after 4th stroke engine. When fresh air come and if there is already some amount of burnt gases already present then there will be prblm in combustion process and it also somehow affect the efficiency of the engine . This is the main reason behind the concept of six stroke engine.
