Offset=Square Root of Roll squared+ Rise squared
For Example:
To find the travel and run for a 45 degree rolling offset with a roll of 11.5 inches and a rise of 15.5 inches:
Solution Steps:
Offset= Square Root of 11.5 inches squared +15.5 inches squared
Offset= Square Root of 132.25 inches+240.25 inches
Offset= Square Root of 372.5 inches
Offset= 19.3 or 19 5/16 (closest 16th of an inch)
Check out the "Rolling Offset" page at (see below). I'm not sure but do a trial run on a couple of cereal boxes and see if this gives you the information you need. The is a "Note" page that shows some ways of a rolling offset calculation.
Very complicated formula Try seeking out a 2nd year apprentice as the UA has books with these formula's which are seldom used
rolling offsets are used in the piping and sheet metal (duct work) trades, a rolling offset changes the elevation and locaton of the piping or duct usually by using two fittings to offset around obstacles. rolling offsets are used mostly when you are limited to the size of the fittings in order to change your elevation and location rolling offsets are used in the piping and sheet metal (duct work) trades, a rolling offset changes the elevation and locaton of the piping or duct usually by using two fittings to offset around obstacles. rolling offsets are used mostly when you are limited to the size of the fittings in order to change your elevation and location
There are many types of rolling offsets. 2 common are rolling offset using 45 degree fittings and a rolling offset using any angle. using 45's Rise: elevation change roll: run of the pipe moving to the left or right Travel: the run of pipe to make the offset Simple formula Travel = SQRT((rise(squared) + Roll(squared) ) x 2) rise = 10" roll= 16" Travel=? travel= SQRT ( ((10 x 10) + (16 x 16)) x 2 ) travel= SQRT ( ((100) + (256)) x 2 ) travel= SQRT ( ( 356 ) x 2 ) travel= SQRT ( 712 ) Travel= 26.68333 or 26-11/16"
A rolling offset is generally an offset requiring a change in 2 directions. Eg. A horizontal offset and a vertical change in elevation. There is additional information required to answer the question. What is the angle of the fittings being used for offset? 15 deg. 30. 45? What is the change in elevation? If this is a flat (no change in elevation offset) using 45 deg., the offset dimension (7') is multiplied by 1.4142 which is the secant and cosecant of 45 deg. The result 7 ' x 1.4142 = 9'-10 13/16" Again, this result is for a flat run of pipe. If we have a rolling offset with a change in elevation of say 1'. We can use the Pythagorean theorem (A2 +B2 = C2) The result would be (1')2 + (9'-10 13/16")2 = 98.99812 sq. ft. The square root of 98.99812 is 9'-11 3/8"
1.4142 will give the travel piece center to center
If there are 2 circles of same size , offset by distance x what is the area of the overlap
1.414. x offset- Straight of 45's
There is no exact formula to lay out pipe miters, but there is information that must be known to calculate the layout. This includes the diameter, wall thickness, angle, and offset.
