What is the multiplier used for calculating a 45-degree offset when bending conduit?

The correct choice for determining the multiplier used when calculating a 45-degree offset in conduit bending is 1.414. This value is derived from the geometry of a right triangle, where the angles are 45 degrees. In such a triangle, the sides opposite the 45-degree angles are equal, which means that for every unit of measurement on one leg of the triangle, there is an equivalent unit on the other leg.

When performing conduit offsets, this multiplier (1.414) is critical because it reflects the relationship between the lengths of the sides and the diagonal of a 45-degree triangle. Specifically, this multiplier comes from the equation for the length of the hypotenuse, where the hypotenuse is ( \sqrt{2} ) times the length of one leg. Therefore, for calculating the offset distance accurately, using this multiplier results in precise bends required for installation.

Understanding this principle is essential for anyone working in industrial maintenance and electrical installations, as it ensures that conduit runs fit properly within the given space requirements.
