A 45-degree offset has to move a line over 14 in. Using the constant 1.414, what is the center-to-center travel?
Answer in in.
19.8 in
Travel = offset x 1.414 = 14 x 1.414 = 19.80 in.

A 60-degree offset has to move a line over 18 in. Using the constant 1.155, what is the center-to-center travel?
Answer in in.
20.79 in
Travel = offset x 1.155 = 18 x 1.155 = 20.79 in.

Two 22-1/2 degree elbows are used to offset a line 9 in. Using the constant 2.613, what is the center-to-center travel?
Answer in in.
23.52 in
Travel = offset x 2.613 = 9 x 2.613 = 23.52 in.
