Question

2. For each of the following elements of a continuum mechanics problem, give an example of a specific property or application of this elements of a continuum mechanics problem applied to biomechanics or physiology (a) The geometry and structure (b) The boundary conditions (c) The constitutive equatiorn (d) The conservation of mass (e) The conservation of linear momentum

Answer 1

2. a. gemoetry or structure :
   while making customised shoes for athletes, the shame and geometry of their foot is taken on clay models ( or plaster of paris for that matter), and then the shoes are made employing the continuos nature of the physical modification to the clay when settling in athletes foot

   b. boundary conditions : for a swimmer boundary conditions along the body inside water play an important role in deciding the power required by the athlete to swim to its fullest potential

   c. the constitutive equation : like the hookes law is used to find the tensile strength of the bones and the loads that can actually be supported by human limbs

   d. conservation of mass : total material intake in a person's body ( for a particular material like Ca ++ ions in electrolyte), the electrolyte levels in the body will always follow laws of conservation of mass by keeping some of these ions in the body and ejecting others as waste while following the law of conservation of mass

   e. conservation of linear momentum : collsion of two athletes on an american soccer field may be injurious to various body parts and the effect of this potentially injurious situation can be found using conservation of momentum equations
