What this calculator helps you find
An overhanging beam places one or both supports within the overall beam length. Set the full length first, then position the pin and roller supports at their actual locations before applying loads to the span or overhang.
Relevant formula
ΣFy = 0 and ΣM = 0
Worked example
A point load placed on an overhang can create a negative moment near an adjacent support. Review both the reaction signs and the complete bending-moment diagram rather than checking only a midspan value.
Use results responsibly
Use this tool for idealized, static two-dimensional analysis and for checking calculations. Confirm units, sign conventions, supports, material properties, and applicable design standards before using results in a project. Review the assumptions and limitations and validation records.
