    - Trusses are of two different types: Perfect and imperfect truss.

    - Imperfect truss is further classified as redundant truss and deficient truss.

    - Unstable or imperfect truss: It is a truss which collapses when loaded. For these trusses n ≠ 2 j – R. Trusses which satisfy the this condition are known as imperfect trusses.

    - The condition for redundant truss is n > 2j – R

    here (n = number of joints, j = number of members, R = number of reaction components)
