The Muller-Breslau Principle for constructing influence lines is applicable to:
AStatically determinate structures only
BStatically indeterminate structures only
CBoth statically determinate and indeterminate elastic structures
DNon-linear plastic structures only
Explanation
Muller-Breslau Principle states that the influence line for any stress resultants or reaction in an elastic structure is given by the deflected shape when a unit displacement is applied. It applies to both determinate and indeterminate elastic structures.
