### thermodynamics - Thermal expansion of a rotating object

I am having a discussion on the thermal expansion of a rotor in a supercharger.The rotor is an alloyI think it is 7000 seriesand is held by a steel shaft.The rotor is 152 mm long,and if I apply the basic thermal expansion equation to it,I find that it grows by 0.203130 mm if IVolume Expansion - OER2GoKey Points.Substances that expand at the same rate in every direction are called isotropic.; In the case of a gas,expansion depends on how the pressure changed in the process because the volume of a gas will vary appreciably with pressure as well as temperature.; For a solid,we can ignore the effects of pressure on the material,and the volumetric thermal expansion coefficient can be Thermal expansion physics BritannicaThermal expansion,the general increase in the volume of a material as its temperature is increased.

### Thermal Stresses Boundless Physics

Thermal expansion is the change in size or volume of a given mass with changing temperature.An increase in temperature implies an increase in the kinetic energy of the individual atoms,which will increase a solids size by a certain fraction in each dimension.Thermal stress is created when thermal expansion is constrained.Thermal Properties Of Materials - Physical Properties Of Thermal stress.The stress experienced by a body due to either thermal expansion or contraction is called thermal stress.It can be potentially destructive in nature as it can make the material explode.For example,cracks can be seen on roads where the heat is extreme.The crack is a result of thermal stress.Thermal Physics2.Thermal Expansion of gases Place the coin on top of the bottle.Now cup your hands around the bottle and observe what happens.Explain your observations.3.Thermal Expansion of liquids Hold the beaker in your hands.Explain what you observe.4.Thermal Expansion of solids - bimetallic strip Heat the strip using the hairdryer or hot air gun.
