Using The Deflection Calculator

To begin, choose a profile type and part number. From there input a length and the expected profile load. When you click "Calculate Deflection" the tool will provide several engineering specifications such as the moment of inertia and yield strength to determine the deflection. You also have options depending on the expected configuration of your solution: whether there will be one fixed end, two fixed ends or the load will be supported on both ends.

Note that as you make adjustments to the part number or profile series, length or load, simply click the “Calculate Deflection” to view updated information. Print your results for comparison or to save the information.
