    Relationship between power and torque

    Thank you everybody, who participated in this discussion, for helping me understand this topic. Now I get it, and I appreciate your help!

    Relationship between power and torque

    From basic physics we know, that: P = M * w/t, where: P - power m - torque w - angle of rotation t - time This can be translated into this formula: P = M * n / 9550, where: n - RPM In other words, a power is directly proportional to torque. Then how does the dyno tests of car engines produces...

    Learning material for Woodworking machines

    I work as a mechanical sawmill machinery engineer. I would like to get some recommendations for university textbooks or any other type of learning material, where I could find instructions on the following topics: 1. Calculating the power of motor which is needed to turn the circular/linear saw...

    Autodesk Inventor and Solidworks - comparison

    I am sorry for my late come back, I was busy Very interesting idea of yours - that less features can bring less confusion. I must agree that if the user is poorly trained, then the less options he has, the easier work is. Of course, all options require some user input, therefore expanding...

    HICAD software

    I was wondering if anybody here would have any opinion about the HICAD software. It is very rare, but some companies use it as the main tool. I would like to hear the experience about it - how does it work for industrial and automotive industries engineering?

    Autodesk Inventor and Solidworks - comparison

    I am starting this discussion here, on eng-tips forum, and parallel discussion on Solidworks forum. I think users here, on eng-tips, might be more experienced in both programs than at solidworks forum, which is the main reason for duplication. So, I have received a job invitation to the company...

    Mechanical engineer: how to work faster?

    After spending much effort on analyzing my work and it's efficiency for the last week, this is exactly what my conclusion is. Those three steps may be the (only?) key to improve the efficiency of my work. This discussion have surely helped me to crystallize this. Thank you again for...

    Mechanical engineer: how to work faster?

    My customer is my boss. We design machines and then use it in our own sawmill, we do not sell it to third party.

    Mechanical engineer: how to work faster?

    a) yes, appropriate amount of time spent on the project is actually a time save. I do my best to perform it, and I actually do fairly little amount of mistakes b) I should think more about the setup and design strategy before starting the design project. I agree, I will think how can I do it...

    Mechanical engineer: how to work faster?

    Yes, I take into account the possible future designs, and I use my modeling technique a good as I can for that. But to be fair - all my designs are pretty unique, so this actually doesn't save me anything. I do it, because you never know when something is going to change, but it wouldn't save my...

    Mechanical engineer: how to work faster?

    I don't know what are you talking about. PDM is a file management system with lots of useful functions. It definitely is NOT time-consuming, frustrating or anything else negative. Furthermore, it is actually inevitable.

    Mechanical engineer: how to work faster?

    My engineering usually takes about 25-50 percent of an overall project time. We have about 15 people in manufacturing, so they build the product fairly quick. Again, we (me?) are here just to find some ideas how to improve the efficiency of constructing and engineering ...

    Mechanical engineer: how to work faster?

    Yes, I take the advantage of it when appropriate. Furthermore, there are functions in PDM like "Move tree" and "Copy tree" - sometimes even better than PAG.

    Mechanical engineer: how to work faster?

    Exact hours spent on the project design depends on the complexity of it. I often get a feedback from my boss that it takes too long for me, and I often agree (although not always, because sometimes he changes the design intent after I am almost finished with every single nut). Surely, better to...

    Mechanical engineer: how to work faster?

    Yes, learning to ask appropriate questions at the beginning of the design process in order to understand the task better is a must. I am doing my best on it. Also, as I said, first should be the basic design, and details should be the last. I sometimes mix this order.

    Mechanical engineer: how to work faster?

    This is true. I have noticed myself that I quite often tend to use too much detail at the beginning of the design process, and if changes appear - certain amount of this work is lost. I shall try to improve this behavior of mine. Thank you for the advice.

    Mechanical engineer: how to work faster?

    Thank you everybody for your time and the input to this discussion. I apologize for my late reply, I was very busy last days. I shall now try to answer post-by-post. PS - I definitely see the need to improve the interface of this forum for better quoting possibility ...

    Mechanical engineer: how to work faster?

    TheTick: I would appreciate if we wouldn't discuss the chain design further, otherwise it would require a completely separate discussion. ornerynorsk: I mean I must use maedler.com, chiaravalli and other catalogs, find out how some things are calculated, and other things on the net. But I never...

    Mechanical engineer: how to work faster?

    Don't say that, I hope there is a hope to come up with something ..

    Mechanical engineer: how to work faster?

    Hello Kenat, thank you for your input. You have raised a very good questions - they are certainly very important. Unfortunately everything is already optimized there... Chains: yes, I model it fully. I need it for the exact length, I usually need a precise length of the chain. Besides, newer...
