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. Turbo-jet engine a type of

Gear generating process This method of gear manufacturing is based on the fact that any two involute gears of the same module will mesh together. In this one of the meshing gears is made as the cutter. The other gear rotates and also reciprocates along the width of the gear blank. Because of the relative rolling motion of the cutter

Slotter Slotter is a type of reciprocating machine. The tool is held in the ram reciprocates vertically and the work piece is held on the table. The slotter has a base upon which the column is being integrated. The column houses the driving mechanism for the ram. The top portion of the ram has the guide ways. With the

Non-conventional machining process In recent years many new materials have been developed. These include titanium alloys, hast alloys, nimonic alloys etc. these materials cannot be machined accurately with the help of conventional machining process so a different method of machining has to adopted. These new method of machining is called as non-conventional type or unconventional machining process. This type of

Wet sump lubrication system This system consists of a large storing capacity of oil at base of the crank chamber. From the sump the oil is drawn by the pump and applied to various parts of the engine. Excess oil after serving the purpose will gradually return to the sump. Splash type lubrication This type of lubrication is generally used

Types of accumulator Weight loaded accumulator It consists of a piston which is loaded with a dead weight and moving within a cylinder this tends to exert pressure on the hydraulic fluid. Potential energy to compress the fluid is generated by the dead weight present on the piston. Concrete block, iron or steel is generally used as dead weight. The

Taper turning methods in lathe machine. Types of taper turning. There are four methods:1. Form tool method 2. Tailstock set over method 3. Compound rest method
4. Taper turning attachment method
Engine bearing The crankshaft if supported by bearing. The connecting rod big end is joined to be crank pin on the crank of the crankshaft through a bearing. A piston pin at the rod small end is accustomed attaching the rod to the piston. The piston pin drives in bearings. Everywhere there is rotating action in the engine, bearings

Milling Machine Milling is the process of removing metal by feeding the work past against a rotating multipoint cutter. The metal is removed in the form of small chips. In milling operation the ratio of metal removal is rapid as the cutter rotates at a high speed and has many cutting edges thus the jobs are machined at a
