Question:

lenght of an uneven object?

I have a project where I need to measure the total lenght of an uneven surfaceI have looked for various instuments online that can do the job, but have not found one that is accurate enoughI need a digital readout in metric that can show the difference to the 100th decimal in mmIf there is no instument out there and ideas on the most accurate way to do this?

Answer:

I think you mean resolution of 0.01 mmThe 100th decimal is 0.000000 00001, ie, 100 zeros But there are many possibilities, it depends on the length you have to measureThe solution is totally different if the length is a cm as opposed to a kmedit: first thing is to get around the unevennessMake a piece of heavy sheet aluminum with a U shaped cut in it a little less than 550 mmThe size of the cut depends on the exact shape of hte objectTrim the cut until it just fits on the piece Now you just have to measure the distance across the cut in the aluminum stock 550 mm ±0.01 mm is very difficult to measure accuratelyThat is 1 part in 55000You will have problems with temperature control, as materials expand and contract with temperature more than thatAssuming you have a controlled temperature chamber(I have to do some math to check this) You need some highly accurate reference standards, perhaps 500 mm and 50 mm, and use those and a good micrometer to get the differencesedit, another approach I though of, although more info would help, is to build a fixture that fits the largest dimensions possible of this object, and allows you to measure the deviation from this easily.
do you mean m-16, i believe its 30 rounds
I very own the twoThe mini 14 is especially a lot equivalent to the AR-15 as of suitable nowsome human beings will disagree yet they are closeThe AR-15 has extra adaptability recommendations however the mini 14 would be extra stablelike each gasoline gun the AR-15 is extra precise yet a clean mini-14 will hit a 4 plate at 250yds that's sufficient for meregardless of what you have reported, the AR-15 is a lot extra handy to strip than the mini-14unlike a Garand or M1A the Mini14 has somewhat suitable tolerances in the set off team and the set off safeguard (for me) has been somewhat complicated to get offi like the mini14 ergonomics extremely extra effective (besides the magazine) however the AR magazine equipment is extra effectiveadditionally Mini 14 mags have come an prolonged way, I even have not something yet triple ok mags that value $18 a bite and run wonderfulin spite of the fact that regardless of what you have reported, the AR-15 is a lot extra handy to strip than the mini-14unlike a Garand or M1A the Mini14 has somewhat suitable tolerances in the set off team and the set off safeguard (for me) has been somewhat complicated to get off.
30 rounds in an M-16 20 rounds in an M-14 Ammo isn't much of a problemYou have extra magazines (usually 3-4 extra), but even besides that, 20-30 rounds is usually more than enough Since you are generally firing semi-automatic with an M-14 or semi/3burst with an M-16, you should almost always be able to hit or suppress a target from even a medium-long distance with a single clip.
