Define Truss analysis-stability
- Identify whether a truss is determinate or indeterminate.
- Identify if the truss is stable or unstable
m = number of members
r = number of reaction components
j = number of joints
m + r < 2*j -> Unstable
m + r = 2*j -> Statically determinate
m + r > 2*j -> Statically indeterminate
If m + r ≥ 2*j -> Check stability visually
