How does the Static Determinacy and Stability Calculator work?
Free Static Determinacy and Stability Calculator - Given a number of joints (j) and a number of members (m), this determines if a truss is statically determinate, statically indeterminate, or unstable
This calculator has 2 inputs.

What 1 formula is used for the Static Determinacy and Stability Calculator?

2j = m + 3
where j = joints and m = members

What 4 concepts are covered in the Static Determinacy and Stability Calculator?
joint
formed when two or more surfaces are joined together
stable
A structure which will not topple over easily when acted upon by a load
static determinacy and stability
truss
a structural member usually fabricated from straight pieces of metal or timber to form a series of triangles lying in a single plane. (A triangle cannot be distorted by stress.)
