Thermal stress
Thermal stress- If we clamp the ends of a rod rigidly to prevent its expansion or contraction and then change the temperature, tensile or compressive stress developed is called thermal stress. The rod like to expand or contract but clamps won’t allow it. As shown in fig. To calculate the thermal stress in a clamped […]

Thermal expansion
Thermal expansion Most of the material expand when their temperature increases. Then the phenomenon of expansion of material when it is heated is known as thermal expansion. 1. Linear expansion– When a rod heated then the temperature of the body increases due to which length of the rod increases , this phenomenon is known as […]
Temperature is a relative measure of hotness or coldness of a body. An object at a higher temperature is said to be hotter than the one at a lower temperature. The S.I. unit of temperature is Kelvin(K). (We must keep it in our mind that , Heat and temperature are not the same thing , […]
