Multiplier for 15 degree bend

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.

Multiplier for 15 degree bend

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. These values are shown in Table 1. These values are constant and do not vary with a change in radii or height. These values assume that there are no bends or arcs in the offset, and that the conduit follows a broken straight line path which it doesn't. These shrinkage multiplier values can be calculated using the calculator below by setting the radius to 0 and adjusting the angle. A change in height does not effect the calculated shrink multiplier while the radius is set to zero.

Distance AB can be found by:.

Master conduit bending techniques, , and calculations with our comprehensive cheat sheet. Learn the basics, types of conduits, tools required, and for efficient and accurate bending. Conduits are typically made of materials such as metal or plastic and come in various sizes. Here are a few common types of conduits:. These tools are designed to help you achieve accurate bends and ensure the safety of the installation.

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. If you know the dimensions of the tube you want to bend, and the angle of the bend, you can use a multiplier to determine the length of the tube you need to create that bend.

Trigonometry, is a branch of mathematics specifically dealing with the sides and angles of triangles. Thanks guys, that is a really good link, just checked it out. Wardenclyffe Replies. Log in. Edit this page. AVS Forum. Any of you guys who run conduit a lot, make your 3 bend saddles using 15,30,15 degree bends? In certain situations I am not even a fan of box off-sets - and use mineralacs for the whole run My advice For a better experience, please enable JavaScript in your browser before proceeding. How do you use 90's in a 3-bend saddle?

A journeyman did try to help and told me maybe I'm not putting enough foot pressure. Location Iowegia. The total shrinkage is What's new New posts. This is an impractical bend, but it illustrates the calculator's accuracy and the effect of the gain around the bends. 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. You should upgrade or use an alternative browser. For 90 degree bends. Last edited: Oct 5, You are using an out of date browser. On page the shrink for offsets is given as hypotenuse - side adjacacent. Trigonometry is a key part of conduit bending. What would make a saddle any harder to pull through than another bend? With algebra then the shrinkage multiplier is equal to Try to use 90s and kicks instead you will waste less bends.
