However, things also move, this includes structures Can actually identify three "categories" of response A.(Quasi)-Static [quasi because the load must first be applied B. Dynamic C. Wave propagation What is the key consideration in determining which regime one is in? the frequency of the forcing function EXample: Mass on a Spring Figure 19.1 Representation of mass on a spring F t多 Paul A Lagace @2001 Unit 19-3MIT - 16.20 Fall, 2002 Thus far have considered only static response. However, things also move, this includes structures. Can actually identify three “categories” of response: A. (Quasi) - Static [“quasi” because the load must first be applied] B. Dynamic C. Wave Propagation What is the key consideration in determining which regime one is in? --> the frequency of the forcing function Example: Mass on a Spring Figure 19.1 Representation of mass on a spring Paul A.
