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. These four muscles at the front of the thigh are the major extensors (help to extend the leg straight) of the knee. They are: Vastus lateralis: On the outside of the thigh, this is the largest of the quadriceps. It extends from the top of the femur to the kneecap, or patella.
Thigh bone: The thigh bone in anatomy is called the femur.. Whichever term you care to use -- thigh bone or femur, it is the bone in the leg that extends from the hip to the knee. The thigh bone/femur constitutes the upper leg, that part of the leg. The word femur is the Latin word for thigh.
