What is the travel on a rolling offset that has a run of 18'', a roll of 24'', and a height of 12''?

To determine the travel on a rolling offset, you can use the formula derived from right triangle relationships. A rolling offset consists of a horizontal run and a vertical rise, with the roll portion between them.

In this case, the run is 18 inches, the roll is 24 inches, and the height is 12 inches. The travel can be found by applying the Pythagorean theorem to the triangle formed by the run, roll, and height.

First, calculate the effective length of the roll portion. In a rolling offset, the travel is obtained by adding the horizontal run to the vertical component achieved through the roll.

The full calculation involves determining the actual length of the roll when considering the angles formed, but in essence, the total travel incorporates all lengths together, factoring in the angles of the offset.

Using these measurements:

1. Convert the measurements into a usable format, considering the geometry of the offset.

2. The formula for travel can be expressed as the sum of the run and the roll:

Travel = Run + (Roll² + Height²)^(1/2)

Here, when inserting the values:

Travel = 18 + √(24² + 12²)
