Why Muscle is an Efficient Shock Absorber
Skeletal muscles power body movement by converting free energy of ATP hydrolysis into mechanical work. During the landing phase of running or jumping some activated skeletal muscles are subjected to stretch. Upon stretch they absorb body energy quickly and effectively thus protecting joints and bones from impact damage. This is achieved because during lengthening, skeletal muscle bears higher f...
متن کاملThe foot as a shock absorber.
A mathematical analysis of the deformation of the foot is developed to determine the role that stretch of ligaments and tendons plays in absorbing shock following impact. Our analysis is based on an anatomical biomechanical model that includes each of the bones of the foot. We calculate the time course of the deflection of the joints and the elongation of the ligaments and tendons and determine...
متن کاملUnilateral Temporomandibular Joint Dislocation after Jaw Thrust Maneuver
A 25-yr-old Iranian woman with incomplete abortion who was diagnosed and scheduled for dilatation and curettage procedures under general anesthesia. After premedication with Fentanyl 50µg and midazolam 2mg and enough pre-oxygenation, anesthesia was induced by sodium thiopental 250 mg and succynilcholine 60 mg with mask ventilation. After completion of procedure, the patient had a period o...
متن کاملRegenerative Shock Absorber for Hybrid Cars
All vehicles use suspension system. The suspension system mainly consists of a mechanical spring and a damper. The damper dissipates the mechanical energy into heat and thus damps down the vehicle oscillations. In a bid to reduce the vehicle emissions, many technologies are being thought to reduce energy losses and also recover energy from the energy losses if any. One such technology is regene...
متن کاملNumerical and Analytical Investigation in Radiated Noise by a Shock-Absorber
In this article, the radiated noise by a shock-absorber is studied. This particular shock-absorber is used in a heavy-gauge shearing line in order to stop the cut steel sheets. Three steps are followed to evaluate the propagated sound in the surroundings; first of all, the plate vibration response is specified after the impact. Secondly, the edges of the plate are substituted by a set of the mo...
