CHEMICAL MACHINING In chemical machining, some chemicals are used to remove material from the required portions of the workpiece. This process is also called chemical milling. Chemical milling is done in the following steps. Cleaning The workpiece surface is carefully cleaned. Masking The portions of the workpiece which do not require machiningis covered with masking sheets. The sheet is cut

Jet propulsion Jet propulsion is based on newton’s second law and third law of motion. Newton’s second law states that the rate of change of momentum in any direction is proportional to the force acting in that direction. Newton’s third law of motion states that for every action there is an equal and opposite reaction. A type of jet engine
