Question

What is the degree of redundancy for the given beam?

• A. 4
• B. 3
• C. 2
• D. 1

Hint:

For structural analysis, always count the number of reactions and apply the equilibrium equations to determine the degree of redundancy.

Answer 1

The Correct Option is D

The degree of redundancy of a structure is the difference between the total number of unknown reactions and the number of available equations of equilibrium. In this case, the beam has one degree of redundancy, which means one redundant reaction. Hence, the correct answer is 1.
