A railwway tunnel in shape of circle has diamet 4.8m. AB is a horizontal line representing the ground rails are laid on and is 3.2m. How do you calculate the height from ground to top of tunnel?

-- Draw a line from the center of the circle to the end of the horizontal rail-platform.That line is a radius of the circle, so it's 1/2 the length of the diameter.-- Draw a line from the center of the circle straight down, perpendicular to thehorizontal rail-platform.Now you have a right triangle inside the circle. The hypotenuse is a radius of the circle ...you know it's length. The base is 1/2 of the rail platform ... you know how long that is.So you have 2 sides of the right triangle.-- Now you can calculate the 3rd side of the right triangle. That's the triangle's height,and it's the vertical distance from the rail platform to the center of the circle.-- Plus one more radius of the circle takes you the rest of the way to the top of the tunnel.Thank you. You've been a great audience. I'm here til Friday.Drop a TP in the jar, and don't forget to tip your waiter.


How can you tell if a railroad line is abandoned?

An unused rail line will be rusted but a line in use will be polished from the wheels of trains. Also, an unused line will usually be overgrown with weeds etc Well, other than the above, you really can't tell. I have known several lines with weeds and other things on the track, and are still used for light freight. Try to (legally) find the closest signal light and see if its active (lit any color). Be very careful. You could also ask your local council, or at the nearest railway station etc. The best option is to assume that any tracks are live. If railroad tracks exist, you are probably tresspassing in the first place. If the tracks are covered in rust, they may not be used that often, but rust won't protect you from a run-away car travelling at 60 mph. Out of a railroad yard possibly 30 to 60 miles away.
