    ndems reacted to DrD in Hands on - manual side   
    The term "hands-on" seems to fit, but I don't think I've ever seen the phrase "manual side." What is this last phrase intended to convey?

    Many years ago, I was involved as an expert in a legal dispute. My company was suing the US Army in a contract dispute. I got a very bad taste for lawyers as a result.
    An Army facility had designed a mechanical system and put out drawings for the system as the basis for suppliers to bid on building the system. There were five major suppliers bidding to build these devices for the Army, and the bidding was extremely competitive. Being higher by half a cent  ($0.005) per unit would mean losing the bid.
    My employer had the misfortune to win the bidding, and we were building this rather complicated mechanical system (around 200 parts) for about $15 per unit with many 1000s to be built. Each week's production would be declared to be a "lot," typically around 20,000 units. The inspectors would draw a random sample for testing, and if all tests were passed, the lot was accepted and the company was paid for the material. If any tests were failed (and there were about a dozen different tests), the lot was rejected and the company received no payment.
    Dimensional tolerances were extremely critical, and the company had taken then into account in the bidding. In suing the Army, my employer was alleging that the tolerances had been deliberately set loose for the bidding while the Army knew that closer tolerances were required in order to consistently meet all the specifications and pass the tests. The Army denied this.
    My job for 18 months was to demonstrate mathematically that there were dimensional combinations within the allowed tolerances that would fail some of the tests, and therefore that the Army had misled the bidders in the original contract negotiations. I did this quite fully, showing that some combinations would work while others would not, even though all were within the specifications on the drawings.
    I was completely disgusted by the attitudes of the lawyers on both sides. The had ZERO interest in the truth; they only care about winning the argument. They were only interested in information that supported their side of the case. If a part of my study did not support my employer's case, our attorneys ordered me to destroy that paper work and to deny that I had ever done it if asked. I refused to do that; the truth is the truth.
    Most of my encounters with lawyers since that time has supported my early evaluation; they are evil men (and women) intent only on winning. Truth means nothing to a lawyer!

    ndems reacted to DrD in Force generated by running machinery   
    There is no simple formula for the force you are asking about. It depends upon the nature of the motions involved. If you would like to post a drawing of your machine (or send it to me by PM), then perhaps I can help you.

    Dr D.
    Pit bulls are some of the gentlest dogs unless they are trained otherwise. A lawyer like a politician only cares, or must force themselves to only care, about winning. How much is training, and how much is evil by their nature is impossible to determine.They present a set of information (I hesitate to use facts). The presented information is turned over to a third party judge/jury who come to a decision based on two or more biased and incomplete sets of information.
    I have sat in court knowing the full story and listening to what was presented which then becomes the only "truth" the jury knows. I have come to realize that we have a legal system and justice is an illusion. I would go one step further and say we have a decision system.
    As engineers we need to get as close to the truth to prevent danger to those using our designs. The legal system needs to reach a decision so the system can move on. And they are very slow to undo a decision even when confronted with information that would have altered the original decision.
    My advice about our legal system, avoid it like a disease. If dragged into it don't expect justice any more than you would expect a fair fight from a mugger.
    Good engineers can keep you out of trouble.  A good lawyer can get you out of trouble. For the first case good is a complement. In the latter, it does not necessarily have the same connotation as the first.
    Praised be to God we made our livelihood as engineers.
