On page the shrink for offsets is given as hypotenuse - side adjacacent. The side adjacent is AB. For convenience this is called the geometric shrinkage. Distance BC is the height and angle 2 is the offset bend angle. Distance AB can be found by:. The values for this shrinkage multiplier are constant for given angles and does not vary for different radii or heights. The third shrinkage multiplier are those given in Zip tables found in handbooks and manuals and largely the result of Benfield's Tables as published in the Benfield Conduit Bending Manual.

NOTE: for offsets bottom-to-bottom and center-to-center should be the same measurement.

Trigonometry, is a branch of mathematics specifically dealing with the sides and angles of triangles. Trigonometry is a key part of conduit bending. Fortunately every type of bend is based off of a right triangle. There's three basic formulas for trigonometry. The values of these formulas play a huge role in determining the unknown sides and angles of a triangle. Typically when bending conduit you decide the theta, and the hypotenuse distance between bends is the unknown value. This is the most common method to conduit bending.

Hypotenuse : The longest side of a right triangle, opposite of the right angle. These values are constant and do not vary with a change in radii or height. The new linear length is 40 inches see below. It may not display this or other websites correctly. These values are shown in Table 1. Recommended Communities. The latter method will put you off by one conduit diameter too big. Figure 1 illustrates proof that the calculator is calculating shrinkage correctly. Log in. From and old boss of mine - "The secret to the use of that bender is to use it as little as possible.

But what happens when you need to bend them at an angle? In this article, we will discuss what multipliers are, why they are important for degree bends, and how to use them effectively. Think of a multiplier as a tool that helps you calculate the length of the tube you need to create a bend.
