With force ratings from 4.5 to 100 lbf (20 to 440 N), these shakers are suitable for a wide range of modal analysis applications. When performing experimental modal analysis and structural testing, the choice of excitation function and system will make the difference between a good measurement and a poor one.
The largest muscle masses in the leg are present in the thigh and the calf. The muscles that make up the quadriceps are the strongest and leanest of all muscles in the body.
