Spiral handrail maths problem. will pay $50AU for correct answer? - how to make spiral handrail
Hello, please help!
I try to make a railing of a spiral staircase made of metal. Dimensions are as follows:
Since the middle of the stairs in the middle of the rear ramp of 510 mm.
Improve Scale 195 mm.
The staircase (or the width of the tread) 275 mm
Angle of about 52 degrees wide (measured from the rail, where he goes.
I know that if I wanted the tracks on a flat surface with a radius of 510 mm when measurment separated from the gate drive and sat on top of the railing posts, the rail contracts on the radio.
Could someone please help me with this math problem?
Thanks in advance
Scobie
I pay $ 50 AU for the first correct formula and correct answer. Thanks

You need to measure total ascent and handrail desirable angle, the wrinkles around the vertical axis rail.
Suppose you go to the track 510mm radius of 1000 mm above floor level 3300mm, the height of H = 2300mm whole and not just turn 270 degrees around the vertical axis.
That was the right angle would make triangles on a sheet of wallpaper, when you roll over a piece of the stairs, and the dimensions
vertical page = 2300mm
Horizontal Side B = 270 * (π/180) = 2403mm * 510mm
Now use Theorem Pyhagorean to calculate the length of the handrail to:
Length = c = hypotenuse = √ (a ² + B ²) =
= √ (2300 ² 2403 ²) =
= 3326 mm \\ \\ \\ \\ \\ \\ \\ \\ u0026lt - that would be the length of the tube bending machine
******
a = 2910mm
b = 315 * (π/180) = 2804mm * 510mm
Length = c = hypotenuse = √ (a ² + B ²) =
= 4041 mm \\ \\ \\ \\ \\ \\ \\ \\ u0026lt - that would be the length of the tube bending machine
*** What is the radio that was to run the railways?
This question can not be mathematically in the affirmative, because if vreach will remain the pre-tilt angle of the arc. He was cutting a tube of 4100mm, then to a full circle, then Streatch vertically until it clicks into place, remove the more than 6 inches
