This amusing incident occurred at the site of my neighbor when marking the foundation for building a house.
That evening I arrived home from work and accidentally went to him to ask about the progress preparation for pouring the foundation. I look, builders have already sketched the axis of the future building, built castoffs, and dug for a couple of bayonets trench shovel.
I do not know how I noticed, but I think accidentally falls on the corner of the building - at the intersection of string stretched rags, and observed with the naked eye that the corner is not straight. I crouched down and tried to eye again, "shoot" evenness angle))) (photo unfortunately does not clearly convey "stupid" angle).
With humor ask a neighbor, why say, decided the angle is not very smooth to do, it's not nice? And he understand that bong!
In the course of a neighbor conversation, interrupted us the eldest of the builders, and shouts, Che, they say, come, and so time is tight - do not fit into the schedule, and you're here with tips climb!
I say to him - my friend, I might think, but the angle does not look quite right. Further, such a dialogue:
Senior team "We control measurement of the diagonals made, so do not prezhivay!"
I: "Let's see, it's 3 minutes Delov!"
He reluctantly takes a laser range finder, gives me the board and says:
- "On, Hold and applied at an angle". Gaugeable to my oversight board, suitable screen pokes with a value of 11,745 m, Gaugeable second diagonal and shows -. 11.752 m.
Well, I think, okay, the error of a few mm. - it is not an error. Can really at the end of the day fatigue effect! At this time the shouts from the far corner of my reproach another mug "Well che, brings your eye estimation you came here pro !?"
I have to check yourself, ask a neighbor angular range and is applied to the corner. And then on to you, the error string stretched shoots about 3-4 mm. 50 cm. length.
Beckons builder, a crowd gathers around me and begin to vigorously discuss how it happened?
I said: - "Gaugeable all sides!"
The neighbors I mutters, saying that he trusts you Th conflict, supposedly, to inflate. I tychu him into a corner and say he see, you see a line in the direction of getting away!
In short made remeasure all parties. And what do you think the result? Diagonal diagonal and two opposite sides diverge by 11 centimeters - Eleven!!!
You may ask how it happened? Most likely, as the complex configuration of the building, once fathom all sides strung laces. After that the correction of the diagonals, shifts them horizontally exposed rags - achieving equal diagonals, but forgetting Gaugeable blunt corners and the control side. As a result, they miraculously turned isosceles trapezoid, Which has the same diagonal are completely equal.
Conclusion!
Identical diagonals does not say that you are equal to the angles of 90 degrees. Always do a comprehensive measurement of all sides and checking angles, because a lot of ways. I do not understand why the builders put on it, and decided to get rid of just checking the diagonals.
Since then, a neighbor invited me to her before each stage, as it were, just look, if all is fine with it! )))) Would be a pity if the fuck up a beautiful home!
That's all, Thanks for your attention!
