Cantilever Weight Calculator

Result: pounds

A Cantilever Weight Calculator is a useful tool for engineers, architects, and anyone working with structures that involve beams or extended arms. Calculating the moment of a cantilevered weight can be a crucial part of designing and ensuring the safety and stability of various constructions. This calculator simplifies the process, providing you with the moment quickly and accurately.


The moment (M) of a cantilevered weight can be calculated using the following formula:

M = Weight × Cantilever Length


  • M is the moment in foot-pounds (lb-ft).
  • Weight is the applied weight in pounds (lb).
  • Cantilever Length is the length of the cantilevered arm in feet (ft).

How to Use

Using the Cantilever Weight Calculator is straightforward:

  1. Enter the weight (in pounds) applied at the end of the cantilevered arm.
  2. Click the “Calculate” button to obtain the moment.

The result will be displayed in foot-pounds (lb-ft).


Let’s say you have a cantilevered structure, and a weight of 500 pounds is applied at the end of a 5-foot long arm. Using the Cantilever Weight Calculator:

  • Enter the weight: 500
  • Click “Calculate”

The calculator will then determine that the moment is 2500 lb-ft.


  1. What is a cantilever?
    • A cantilever is a structural element that is supported at one end and free at the other, like a diving board.
  2. Why is calculating the moment important?
    • Calculating the moment helps determine the structural stability and safety of a cantilevered structure.
  3. Can I use this calculator for metric units?
    • No, this calculator works with pounds and feet. You may need to convert units for metric measurements.
  4. What is the standard value for gravity used in this calculator?
    • The standard value for gravity is approximately 32.2 ft/s².
  5. Can I use this calculator for other units of weight?
    • Yes, as long as you input weight in pounds, the calculator will work.
  6. Is this calculator suitable for any type of cantilevered structure?
    • Yes, this calculator can be used for various applications like designing bridges, beams, or any other cantilevered structures.
  7. Is there a limit to the length of the cantilever?
    • There’s no strict limit, but extremely long cantilevers may require additional considerations.
  8. What happens if I input a negative weight?
    • The calculator will still provide a moment, but it will be negative, indicating a moment in the opposite direction.
  9. How precise are the results from this calculator?
    • The calculator provides results with two decimal places, which is usually sufficient for most applications.
  10. Can I embed this calculator on my website?
    • Yes, you can easily embed this calculator using the provided HTML and JavaScript code.


The Cantilever Weight Calculator is a valuable tool for engineers and architects. It simplifies the calculation of the moment of a cantilevered weight, which is essential for designing and ensuring the safety of structures. Whether you’re working on a small-scale project or a large construction, this calculator can save you time and help you make more informed decisions.
