Question

difference between redundant and deficient truss

Answer 1

Deficient structure means the structure in which the required reactions are not provided. Generally these structures are unstable.

Redundant structures means the structure provided with the extra reactions required for stability of structure. These degree of redundancy can be found out by some standard ways or formulae. These structures are able to carry more load and it is always beneficial.

i hope it helped :(

Answer 2

Difference between redundant and deficient truss :

• Sufficient number of member is not contained by deficient truss in case of transfer the load and making it stable. These structures are generally unstable.
• Excess number of members are contained by redundant truss. The process of determining all the members forces solely the set of equilibrium equation, is made impossible.
