Air compressors can be classified into two main types: positive displacement compressors and dynamic compressors.

• Positive displacement compressors work by trapping air in a chamber and reducing its volume to increase pressure (e.g. reciprocating, rotary screw)

• Dynamic compressors use rotating impellers to accelerate air and convert kinetic energy into pressure (e.g. centrifugal, axial flow)

• Each type has its own advantag...read more

Stress in mild steel refers to the internal resistance of the material to deformation under load.

• Stress in mild steel is the force applied per unit area of the material.

• It is typically measured in units of Pascals (Pa) or Megapascals (MPa).

• Stress can be tensile (stretching) or compressive (squeezing) depending on the direction of the force applied.

• Excessive stress can lead to deformation or failure of the material.

• Exam...read more
