The 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 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 کاملWhy 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 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...
متن کاملMembrane skeleton: How to build a molecular shock absorber
The human red blood cell is a remarkable transport system, perfectly suited to its task. Its cargo, hemoglobin, is carried effortlessly throughout the body, where it is serves as a molecular shuttle for oxygen and other gases. Although the red blood cell is not itself motile, it leads a very dynamic existence in the circulatory system. During the course of its travels it must be durable enough ...
