Muller-Breslau principle is used in analysis of structures for _____________.

drawing an influence line diagram for any force response in the structure
writing the virtual work expression to get the equilibrium equation
superposing the load effects to get the total force response in the structure
relating the deflection between two points in a member with the curvature diagram in-between

Correct answer: drawing an influence line diagram for any force response in the structure

Solution

The Muller-Breslau principle states that the influence line for a specific response in a structure can be derived by considering the effect of removing or altering the support or loading condition associated with that response, making it essential for drawing influence line diagrams.
