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.
Tight calf muscles is a common problem in athletes especially runners. The calf muscles are the Gastrocnemius muscle and the Soleus muscle. The big muscle at the back of the lower leg is called the Gastrocnemius. Itâs the muscle thatâs visible from the outside of the body.Under it, and further down the leg is a smaller muscle called the Soleus. The larger and most superficial of the two muscles, the Gastrocnemius, attaches to the heel with the Achilles Tendon and originates behind the knee on the femur, crossing two joints.ight calf muscles is a common problem in athletes especially runners.
