    Cantilever truss: It is defined as a truss which has one end fixed and other end free.

    The number of reaction components in a cantilever truss are 4, number of members are 10, joints are 7

    Therefore, using the condition n = 2j – R

    10 = (2 x 7) – 4 = 10

    Hence, it is concluded that it is a perfect truss because the condition is satisfied.
