Guesstimating Weight

[Creamcracker]

Okay....so I put the bathroom scale under the tongue and it came up to 75lbs.....then I put the scale under one of the wheels and it went to 350lbs...I didn't put it under the other wheel since I figured that it would come out the same...so 350+ 350+75 gives me a total of 775lbs.....How close do you guys think that guesstimate may be to the actual weight? Any thoughts?

I would think you would need three scales??? Seems you would be shifting the lbs a little.

Phil,

That's an excellent method - accurate to the accuracy of a bathroom scale.

The weight shift from lifting one wheel up a few inches is negligible.

Great.....now I've got to do it

Might want to put it under the third wheel as well - I Made the same assumption, but when I weighed it I came up five pounds heavier! - I think it has something to do with the placement of the tongue jack on one side

Mmmm! 5lbs? I think that's within a plus or minus error range that's acceptable.

I do not know how accurate my weight was. I tried to weigh the frame to see how heavy and went to a couple of scales meant for 18 wheelers, they couldnt even weigh that little. Well i found a grainery and they let me use thier scale i did both the jeep and frame and then just the jeep alone. the difference came out to 460 pounds. I was off on my guess by 80 pounds or so.

in fact you did REAL well. Summation of Z forces must equal the total z force. Next concept summation of moments also equal zero

There will be a slight error, but it's noise -- 5 lbs out of 750 lb is less than 1% boo ya!
