Pythagorean Theorem- tool

Re: [peterk] Pythagorean Theorem- tool

In reply to: Aren't most ladder rungs 12", or 1 ft apart? If you count how many ladder rungs there are within the red-white colors, you can figure out how the A is painted, like 75' per section, 8 colors, etc...?
Why would rungs in a metric country be 12 inches apart? I would think it more likely that they would be spaced by some measurement in centimeters (or fractional meters).

i would NEVER use that metode,i rather use my altiwatch then.most objects i jump,cant take a "small"misjugedment.I only tryed this once and will never tollerate it to hapen again.If i cant messure it proberly,atleast just before the exit,then im not jumping it,that simpel.

I work in oil refinery and all technical measurements of pipes or similar stuff are in ". We don't use cms. Probably because it is USA oil rafinery that was bought some time ago.

About ladder rungs, I climb them pretty often on my work, and last night as I was climbing smokestack I found out that space between rugs was smaller than on ladders that are on my work.

In my experience there is no way you can count on a set distance of 12" between rungs.

Did a quick check at the department library, I am currelntly stationed at a nuclear powerplant and we do use a bit of such things, and the width varies in 3 different catalogues between 10 - 11" (260 - 280 mm).

Might make a difference, since I don't do BASE I can't really tell.

My .02 anyway.

In reply to: i would say that it need more than just 1 distance.
The laser I know of is made for measuring both distances and heights, so it´s a combined laser-clinometer device.

That way the device can check the angle between a and c with the clinometer, at the same time as the laser finds out distance c. Then it´s just simple trigonometry for the software to do.

So only by pointing the laser to the top of the object, I get the height of the object on the display.

Since I don´t need distance a, it doesn´t matter if the object is perpendicular to the ground, or if it´s underhung or overhung.
Another good thing about not needing to measure distance a: Near the ground there can be things like trees and big rocks between me and the object, making it impossible to use the laser to find out that distance.

There are lots of things out there for people with too much money...

In reply to: Why bother with measuring c? When you're looking at the top at a 45° angle, a and b are equal...(for example, when you're looking at the top of an A at a 45° degree angle, the distance to its base is the same as its height)
Or does this have another use that I can not grasp with my yet-untainted-by-BASE mind?

Easy one for you jerry,How do you know where 45° is?

Re: [tosca] Pythagorean Theorem- tool

Where can we grab one of those? Electronic clinometer?
take care
space, with an analog clinometrer..

Re: [tosca] Pythagorean Theorem- tool

Distance and height can be the same thing, the diff comes by inviting gravity to partake.

Re: [base283] Pythagorean Theorem- tool

you can check out the clinometer and laser here, on page 20-23. There is no more information on the website, so send me a PM or contact someone else at Haglöf Sweden (info@haglof.se) if you have any questions!

How high?

Can any of you guys take a guess how high this A is? I got pictures from a wuffo friend who is living near it.
I believe that Tom B. from ABA jumped it, if I remember correctly.

Thanks.

Re: [Kinaa] How high?

werry hard to say by pics and i could be far away here but.. 250-300ft?

Re: [Faber] How high?

I don't have idea. Friend that lives near say "it is realy tall" but he is a wuffo and I doubt his ability to assess altitude.
