Sensible Heating
The heating of air without any change in its specific
humidity is known as sensible heating. Let air at a
temperature of td1 pass over a heating coil whose

Comparison of Stress and strain
In plane stress problems, stresses exist only in the x-y plane.
In axisymmetric problems, the radial displacements develop circumferential strains that induce

Impact Loading
The strength of machine elements is considered it is assumed that the loading is static or applied
