In summary, when calculating bending in English units, it is necessary to use feet for all dimensions. This applies to both the tube and the load variables in the bending equation. For example, a 1x1x0.125 inch tube would be converted to 1/12 x 1/12 x 1/96 feet. The comparison between steel tube and doug fir 2x8 for deflection under a uniform load of 1000lbs over a 7ft length can be done using the section and young's modulus of each material. This information is relevant for designing a steel tube roof truss for a 12ft x 12ft gazebo with an 18 degree pitch.

so when i use english units to calc bending so i use Feet for all dimensions?

Perhaps you could elaborate a little?

Bending tubes should work just fine in any measuring system.

well, if i use english system (feet, psi, etc) i suspect i have to stay in those units for all variables in bending equation. if my tube is 1x1x0.125 inch then i convert that to feet?? so 1/12 x 1/12 x 1/96 ?? i am comparing steel tube to doug fir 2x8 for deflection of uniform load W across length(L) 7ft where W=1000lbs. i have section and young's modulus of each material, etc. my application is a roof truss but looking to use steel tube instead of 2x8 wood, its a 12ft x 12ft gazebo roof with approx 18 degree pitch.
 

FAQ: Bending Tubes with Feet: Efficient Calculation in English Units

How can bending tubes with feet be efficient in calculation?

Efficiency in calculation for bending tubes with feet refers to the use of English units, such as feet and inches, which are more commonly used in the United States. This makes it easier and faster for engineers, technicians, and other professionals to perform calculations and measurements without the need for unit conversions.

What are the benefits of using English units for bending tube calculations?

Using English units for bending tube calculations offers several benefits. First, it allows for easier communication and collaboration among professionals in the United States, as they are already familiar with these units. Additionally, English units are typically easier to visualize and understand, making it simpler to interpret and apply the results of calculations.

Can bending tubes with feet be used for any type of tube?

Yes, the method of bending tubes with feet can be used for various types of tubes, including round, square, and rectangular tubes. However, the specific calculations and techniques may vary slightly depending on the shape and dimensions of the tube.

Are there any limitations to using English units for bending tube calculations?

While using English units for bending tube calculations can be efficient and convenient, it may not be suitable for every situation. For example, if the project involves collaborating with professionals or using equipment from other countries that use metric units, it may be more efficient to use metric units for consistency and accuracy.

How accurate are the results of bending tube calculations using English units?

The accuracy of the results depends on the accuracy of the measurements and the precision of the calculations. As long as the measurements are taken correctly and the calculations are performed accurately, the results should be just as precise as those using metric units.
