AdministrationCâu 79 / 110
On an isometric, a 45-degree offset must clear an obstruction, producing a 24 in vertical offset. For a 45-degree fitting the travel (diagonal) length equals the offset times 1.414. What is the travel length of pipe between the two fittings?
a.17.0 in
b.24.0 in
c.33.9 in
d.48.0 in
Giải thích
Travel = offset x 1.414 = 24 x 1.414 = 33.9 in. For a 45-degree offset the vertical rise, horizontal run, and diagonal travel form a right triangle where the diagonal is 1.414 (the square root of 2) times the offset. This constant lets a plumber lay out offsets directly from the required rise.
