Truss type
Simple triangle
Result
How it works
- Enter your truss geometry and support conditions.
- Enter the applied load.
- Get the axial force in each member, tension or compression.
The method
The method of joints applies equilibrium equations at each connection point, solving member by member for the internal force each one carries.
FAQ
What method does this use to solve the truss?
The method of joints, which applies static equilibrium equations at each pin joint to solve for the axial force in every connected member.
What does tension vs. compression mean for a member?
A member in tension is being pulled apart (stretched), while a member in compression is being pushed together (squeezed) — the distinction matters for material and connection design.
Does this handle any truss shape?
This covers simple, statically determinate trusses; more complex or indeterminate truss geometries need more advanced structural analysis methods.
