Right angle problem?Hello, #2 20121118 10:28:21
Re: Right angle problem?Hi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20121118 19:36:08

Re: Right angle problem?The ramp is 50 feet long. You could say the ramp starts at 0 degrees angle. I said one side was "one foot" just as a reference point. This is in a river not water with a tide to observe. There is arbitrary rise and fall from the dams being opened and closed but it would be very difficult to map and would not provide any data of value. I need to understand how to start the process from 0 degrees angle and how to convert or show the change in height of one end of the ramp and how much the ramp will shorten as the water rises, ideally in one foot increments. One end of the ramp is fixed and does not move. As the water rises, the other end of the ramp rises (changes angle) and the ramp effectively shortens. These are the main questions I am trying to answer. I have to make a chart that shows the change from 0 feet to 21 feet (the worst recorded flood). I hope this helps. #6 20121220 08:15:58
Re: Right angle problem?Hi; We have water rise in feet in the first column and the effective length of the ramp is in the second column. This is my drawing showing the biggest flood of 21 feet. The chart indicates the ramp will only stretch 45.3762 feet across. The formula that generates the above table is: In mathematics, you don't understand things. You just get used to them.

Re: Right angle problem?Hi;
He has one end of the ramp fixed and the water raises the other end up. The fixed end acts as the center of a circle. In mathematics, you don't understand things. You just get used to them.

Re: Right angle problem?Hi;
From the way he explains it, it sounds more like a drawbridge. I hope the OP comes back before 12 / 21. In mathematics, you don't understand things. You just get used to them.

Re: Right angle problem?Hi dvcochran;
Oh boy! Now me olde head will double in size and I am already having trouble fitting it through the door. In mathematics, you don't understand things. You just get used to them.
