What is geological Redox?
•Redox reactions can cause a change in volume •2Fe + 1.5 O2 > Fe2O3
Is volume a physical or a chemical change?
Volume is a physical quantity not a change. However CHANGE in volume is a physical change.
Could you show the derivation of elastic strain energy per unit volume?
U= vol metric integral1/2(stress* strain)dxdydz
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 temperature does a gas change?
any increase in temperature will cause gas to occupy a larger volume, any decrease will shrink the volume to a point it becomes liquid. further decrease will cause a solid to form. at -273 degrees celsius everything is solid
Which of the following is dimensionless quantity a. stress b. strain c. momentum d. force?
Strain is dimensionless quantity because strain is the ratio of the same quantities like change in length/original length,,change in volume/original volume. e.g tensile strain=(change in length)/(original length)=m/m (S.I unit) so its a dimensionless quantity.
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.
Is defined as ratio of uniform stress to volume strain?
is defined as ratio of uniform stress to volume strain
WHAT IS VOLUMETRIC?
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.
Does water keep its volume?
In general, yes, but lots of things may cause its volume to change. The volume will change if temperature or pressure change, or if something dissolves in the water. Volume may also decrease by evaporation.
What change in the stream would cause pebbles to be deposited farther offshore?
A greater volume of water would cause this.
Characteristics for volume?
volume is the measurement of the amount of space that an object takes up.
What is strain gauge?
* a device that responds to mechanical strain. with a small change in resistance. ... * device for determining the amount of strain (change in dimensions) when a stress is applied
What is the relationship between stress and strain?
Stress is the load per unit area acting within a material. It can be thought of as the internal resistive response of a material to an externally applied pressure.Strain is the change in shape of an object in response to external pressure or internal stress. To complicate matters, strain causes the transmission of stress through an object (as in simple terms the strain causes an internal "movement" causing one part of the inside of an object to press against the material next to it generating stress in this region, this in turn can cause more strain and so on!).There are a number of differing types of strain, for example axial strain is defined as the change in length relative to the original length of an object (e.g. a steel wire being stretched). This change in shape is also called deformation. Volumetric strain occurs when an object is squashed or pulled on all sides leading to a change in volume.
What is geological Redox?
•Redox reactions can cause a change in volume •2Fe + 1.5 O2 > Fe2O3
What is a strain and why the strain should be developed for industrial process?
strain = change in dimensions/area strain is of 3 types 1)linear 2)aerial 3)volumetric
What is the percentage formula for change in volume?
Percentage change in volume= Change in volume/intial volume X 100
