MT-1620 Fall 2002 Figure 20.3 Ideal dynamic response of single spring-mass system to constant force Dynamic response Static response 七 Note that Dynamic response= 2 X static response dynamic magnification factor'-will be larger when considering stresses over their static values Know this doesn't really happen(i. e response does not continue forever) What has been left out?
