If I lived in North Carolina, the vessel would weigh the same as if I lived in North Dakota. No it wouldnt !!!! For all practical purposes, yes it would. The MASS would be the same but not necessarily the weight. For all practical purposes, yes it would. Wgt .= mass X gravitational acceleration. Thank you for the math lesson. You tell me off the top of your head what the exact "gravitational acceleration" at Wrightsville Beach, North Carolina is, and also that of Williston, North Dakota, and figure up the equation you posed above to tell me the exact difference between the two. This is as significant as wheels on a platypus. The variation of weight between any two given locations within 500 miles, would not matter in the least to what kind of vehicle would be required to tow this vessel, nor would it matter in the least to the real-world weight of this vessel, as it is measured in a realistic manner. There may be up to a fraction of a pound of weight, but in the grand scheme of things, that is statistically insignificant. Perhaps if I were towing this vessel on the moon, it might matter, but I am not concerned with theory, I am concerned with real world practice. And in any case, it is now totally irrelevant, because I cannot use this, or any other boat large enough for me to utilize in the manner I wish to. I would have to cruise it over 200 miles to get to the nearest coast, to be able to go anywhere with it, other than up and down a short amount of the local river front. I cannot take it to any of the local lakes, and this is something I had wanted to do. Weight is not a constant value and varies due to local (and varying) gravity values. The 'local' acceleration to do gravity anomalies for each location and altitude will be different and you need to ascertain what the local gravity acceleration is. Mass is constant but weight never is...... just like displacement values vary with the density of the water. You are choking on a flea, and swallowing a camel. I do not know about you, but I cannot look at any item this large, and determine it's weight at a glance, down to the fraction of an ounce. For all practical purposes, and in the real world, not that of theoretical mathematics, the boat might weigh 7000 pounds in North Dakota, and 7000.00002 pounds in North Carolina. Of course this is just as much of a stretch of the theory of gravity as your comment that it would not weight the same, and just as helpful. Thought I'd add to this never ending 'moebius loop' thread. Perhaps your efforts would have been better exerted, had you just addressed the questions I wished to have answered, than in dwelling over miniscule details that matter not a whit to the issues at hand. I thank you for your reply, but it served no practical purpose. Except possibly to discourage me from wanting to participate. --- - Topic-Mimara Unique in the World! --- -=- This message was posted via two or more anonymous remailing services. |
