The deformation of the bar per unit length in the direction of the force is called linear strain.
The Poisson's ratio is the ratio of lateral strain to the linear strain.
The ratio of change in volume to the original volume is called volumetric strain.
The bulk modulus is the ratio of linear stress to the linear strain.
D. The bulk modulus is the ratio of linear stress to the linear strain.
Two constant volume and two isentropic processes
Two constant pressure and two isentropic processes
Two constant volume and two isothermal processes

Gauge pressure = Absolute pressure + Atmospheric pressure
Absolute pressure = Gauge pressure + Atmospheric pressure
Absolute pressure = Gauge pressure - Atmospheric pressure
Atmospheric pressure = Absolute pressure + Gauge pressure
