What equations link angular and linear momentum If you exert a force on a free floating body it will have angular and linear momentum In what proportions and how are they linked?
angular momentum = linear momentum (of object) x perpendicular distance (from origin to the object) where x stands for cross product. angular momentum = mv x r (perpendicular dist.)
What is elastic strain energy?
Potential Elastic Energy.

What is volumetric strain?
Volumetric strain of a deformed body is defined as the ratio of the change in volume of the body to the deformation to its original volume. If V is the original volum and dV the change in volume occurred due to the deformation, the volumetric strain ev induced is given by ev =dV/V Consider a uniform rectangular bar of length l, breadth b and depth d as shown in figure. Its volume V is given by, This means that volumetric strain of a deformed body is the sum of the linear strains in three mutually perpendicular directions.
Which fibers are seen in embedded in the matrix of connective tissue?
The matrix of connective tissue is composed of collagen, reticular, and elastic fibers embedded in ground substance (typically composed of water with stabilizing proteins). The fibers are made by fibroblasts and the most abundant in the body is collagen, while the least abundant is elastic.
What is material elasticity?
A material is called elastic if the deformation produced in the body is completely recovered after the removal the load. For ideally elastic materials, a single valued (linear) and time independent relation exist between the forces and the deformations. Although it is hard to find an ideally elastic material, most of the materials can be considered elastic at least for a specific range.
How does a rigid body differ from an elastic body?
An elastic body will stretch when loaded. A rigid body willl not. A rigid body is a theortical body only in which stiffness is infinite.
What is heat strain?
heat strain or the thermal strain is caused due to the temperature changes. A solid body expands as the temperature increases and contracts as the temperature decreases.this causes the thermal strain. for a homogeneous and isotropic body the thermal strain is caused by change in temperature. thermal strain = coefficient of linear thermal expansion * change in temperature where the coefficient of linear thermal expansion gives the strain per degree of temperature.
What is elastic force?
Elastic force is when something is being stretched or compressed.
What is matrix phase?
matrix phase is continous body constituent which encloses the composite
Young modulus of perfect eleastic body?
for a perfect elastic body the stress strain graph is always linear, meaning stress is always proportional to the strain through a constant i.e., the young's modulus of elasticity which is proportional to the slope of the linear property of the stress strain graph. if a body is ideally plastic it means to have infinite linear line from the centre of the stress strain graph. A linear line like this could have any slope=tan θ. this linear line could have any angle meaning any slope can values between 1 and 0 implying that young's modulus could be any value.
What supports the body of sponge?
elastic fibers
What is tough elastic tissue in your body?
pop
What is a bit matrix or bits matrix?
i believe you are refering to the matrix on a pdc drill bit. if all the cutters were missing when you pooh, chances are you have ground into the bits body, or the "matrix".
What is linear expansion?
If a body is heated and after heating the body if the expand in one dimension then it is called linear expansion
How does elastic energy connect to daily life?
the elastic band in a sling shotrubber bandsthe tendons that connect muscles to bones in your body store and release elastic energy with each stepetc.
