The calculation involves two right-angled triangles. The first triangle has sides 'a' and 'b', and its hypotenuse 'c' is found using the Pythagorean theorem: c = sqrt(a^2 + b^2).
The hypotenuse 'c' from the first triangle becomes one of the legs of the second triangle. Since this is a 45-degree right triangle, both legs are equal to 'c'. The 'travel' (h) is the hypotenuse of this second triangle, and it can be calculated as h = c * 1.414.
A rolling offset occurs when a pipe moves in a horizontal, vertical, and lateral direction simultaneously, effectively cutting diagonally through a space. The video aims to explain how to calculate the dimensions for such a pipe.
The specific type of rolling offset discussed uses two 45-degree fittings. The total distance the pipe travels from its start to end point is referred to as the 'travel'.
By solving these two triangles, the dimensions for a 45-degree rolling offset can be determined. The presenter mentions that a follow-up video will provide a practical example.
