    Hi Does the frame have to be non magnetic? It might be more cost effective to have it manufactured in one piece of steel, laser marked and folded.

    Hi all, I am in the process of designing a board game that I invented on a 3D surface (Bevelled Cube). The structural skeleton is made from plywood and slotting into this there are thin metallic tiles. Onto the magnetic pieces move. My plan is to raise money through a Kickstarter campaign for 100-200 Sets, I am pretty optimistic about it things are going well:). However: One problem that has crept up is the high cost of laser cutting. I feel like the quotes I get from Metal laser cutters are too high. Bellow is diagram of the pieces I need to create A single game (48,24, 8). Most metal cutters ignored my request, I think this is because I asked for a prototype set of pieces and I did not sound professional. One MetalCutter was nice enough to cut me a Proto Set of pieces however his quote for 100 Sets sounds too expensive to me. So finally getting to the point: I was wondering if someone can please estimate the cost for the Base Quantity x 100. Keeping in mind I am using an...

    Notknowing how to think about this concept, I am contemplating how some motors useexponentially larger amounts of power to just to double the speed. So will thatmean that at 1500 watts the vehicle would slow down on the given hill, than Icalculated? And ifthe Elf pedal-car can climb the hills that they claim, it is definitely notlimited to the one HP the motor is rated at. And they use a 1:1 gear ratio! Thismotor is rated at 1.6 HP (1193.6 watts) so the top cruising speed should begeared to about 21.6mpg for near to sea level....on a 5.6% grade. What withthat being 20% less than the 7% grade I want to climb. Or do I need tocalculate an exponentially smaller grade?? if so, HOW? And ifyou understand that can you tell me if this motor is this a compoundseries/shunt motor? Is this understandable at all?

    A load cell is s transducer that is used to create an electrical signal whose magnitude is directly proportional to the force being measured. There are various types of load cells including hydraulic, pneumatic and strain gauge load cells.

    A transducer is a device that takes one type of signal and transforms it into another type. A load cell is a specific type of transducer that transforms force into electrical signals. There are pressure transducers also.

    Reality of global labor market According to the latest report of International Labor Organization (ILO) established on May 19 2015, only ¼ of employees have a stable job, which leads to an unrest spread in the world labor market. The report shows that paid work only accounts for half of the total jobs, with significant differences between regions. Another trend is the increase in the part-time job. In most surveyed countries, part-time jobs developed a lot more than full-time in the period between 2009 and 2013. These figures suggest a world of work is more and more diverse. In particular, Asia emerged as a highlight of the labor market. New center of labor market

    I really do not know how to think abou this, I want to know ratio I should use for a single gear on a specific hill I am wanting to use no more than 2 brake horse power at the axle. for a moped velomobile. I understand that most people just don't even thinnk abou tthese things, and just use all the power they need to climb a hill. I used this calculator on the 'streamlined trike' setting. I assume that it is taking into account a two stage gear reduction loss of 15%. http://www.kreuzotter.de/english/espeed.htm The motor I want to use produces 1500 rpm at 1500 watts Ie: 3”pulley on motor/12”rim pulley on drive wheel= 4:1; 1500rpm/4 =375 rpm

    Hi adarnton, First, I should let you know that this solution worked only temporarily. The problem was deeply rooted in Windows (at some point, for example, I couldn't even use windows update, or even open the task manager, all because of .NET Framework), and eventually I had to end up taking more serious measures, I used method 2 here. I didn't lose any file but I did have to reinstall some software afterwards, before doing this I completely removed SW and I reinstalled it after Windows was repaired. Maybe your problem is different, and you might be more lucky just by doing what solved my problem provisionally. Keep in mind that these steps below were my last resort before reinstalling Windows, so make sure you have tried other options to fix .NET Framework, if none works, then try the following: 1. Download the .NET Framework Cleanup Tool 2. Run "sfc /scannow" from cmd with admin privileges (check the link to know how to use this tool) 3. Reboot in safe mode 4. Apply the...

    Three types of mechanical design: 1. Adaptive Design: In this the designer adapts the design and makes minor alterations or changes to suit the requirement. 2. Development Design: This is the development design from the existing design with the final product being distinct different from the existing one in terms of materials, cost, or functionality, or method of manufacturing. 3.New Design: This involves lots of research, skills, technical ability and creativity. Such designs can generally qualify for a patent.

    Based on the inventors and my experiments a company in Germany has offered to build two wheels. One for UK and one for Germany. There idea is to carry out tests in situ... They have many staff to put full time on this project. They claim there is an inventor in Germany who is achieving off balance of a wheel using water and injected air between 6 o'clock where the air enters the water and 12 o'clock where the air exits the water. The different densities are apparently achieving a 2.5kw input of compressor and a 10kw output.

I too cannot open any parts regardless of format .sldprt, .step, .iges originating anywhere, my own files, downloaded files, files from a colleague. and a series for updates, uninstall/reinstall, etc. have been zero help. Very frustrating. I'm glad to hear you found a solution, and hopefully it applies to me too. Thanks!

    As said above, the spring's energy is going into retracting the cord. If you want it to do any more work, you'll need a stronger spring, which means it will take more energy to pull it. There is no free lunch.

    The link I provided is for a Company that manufacturers safe and bank vault time lock mechanisms - these are designed to be set prior to closing the safe door and then when set and the door is closed and the boltwork thrown, they lock and will not unlock until at least one of the movements has wound down to zero. They always use at least two movements for redundancy in case one breaks, and in larger vaults or earthquake sensitive areas, 3 or 4 movements are made use of. They are incremented in hours and can typically be set for a maximum of six days (144 hours). A strong mainspring isn't required, owing to the operation method - when the safe door is open, a cylindrical bar (called a snubber bar) that is connected to the locking mechanism of the safe, sits inside the body of the time lock housing (you'll see a cylindrical hole on the side of the units on the STB page). When the lock is primed, by pushing in a mechanical button, it compresses a spring. When the door is...

    Is the item rotating continuously? Do you need the torque to accelerate from a stop. Is the axis of rotation vertical as shown in your first picture? This system is terribly unbalanced. This will cause large fluctuating loads on the motor shaft, bearings and mounting points. Not good at all.

    Thank you very much, for the answer. If you have maybe any idea, about materials and mechanics system, and which software to use to design it usually? I would like a kitchen timmer like mechanism, with quality metal gear, seen trough 4cm plexy glass circle, and instead of hammer hitting the ring bell, it would release the lock. The mainspring i suppose, should be very strong, to keep up to 12 hours maximum time option, but units only by hour. Anything simmilar did you see in histroy, where the option was only used by hours as units? How to achieve this mechanically and what really are the biggest challenges, by your oppinion? Best regards Marko
