Question

state the condition of redundant truss​

Answer 1

Such trusses cannot retain their shape when loaded. In a redundant truss the number of members in it are more than that required in a perfect truss. Such trusses cannot be analysed by making use of the equations of equilibrium alone. Thus, a redundant truss is statically indeterminate.

Answer 2

Answer:

Redundant truss is statically indeterminate. In a redundant truss, the number of members present in it are more than that required in a perfect truss. ... Thus, redundant truss are those additional members or supports which are not necessary for maintaining the equilibrium configuration
