Vibratory compaction: In a rigid die pressure and vibration applied at one time to a mass of powder. Finding level of densification it is used lower pressure when we compare it with ordinary die compaction. There have a disadvantage of vibratory compaction such as equipment design of practical apply in tooling and presses. Continuous compaction: Continuous compaction mainly used in simple shape some examples are plate, sheet, tube and rod. Most of the commercially techniques entangle following loss powder between set of vertically oriented rolls. The roll small distance is set up a compact of desired properties. When we compare it with operation of conventional rolling powder rolling speed is less.  Slip casting:    Slip casting have some limitations for it’s extent metals and broadly used in ceramics. Slip casting process slip firstly prepared which is free from liquid vehicles and additives to prevent particles setting. Then the slip is placed in mold

A spacecraft which is flying as like as a bird outer surface of earth and used as a vehicle.  There are many spacecraft objectives such as look   earth, make a communication between earth and outer line of air space, search for new planetary, exilement human and transit cargo. Sputnik 1 which is flying to earth outer surface and it   is the first spacecraft in earth. In 1967 Russia start sent spacecraft in earth outer surface which is mainly target for Soviet. About one hundred spacecraft Russia fly in sky and also facilitation provide on   International Space Station.                  United States fly their Space Shuttle more than Russia about 135 space Shuttle which start in 1981. And their Space Shuttle give facilitation to Spacelab . Before some era scientist use a spacecraft or space shuttle which is not reusable for this reason cost is much high. But developing of Spacecraft and Space Shuttle is now reused. There have some bad impact on environment when scientis

Marine steam engine which is more used in ship for creating power for supply to mechanical energy in a ship. Reciprocating steam engine is more used in ship.  After world war II people made steam engine which create a large amount of power. But day by day change of technology now more used in ship diesel engines and steam turbines. In 1712 Thomas Newcomen first commercially developed Marine Steam Engine who was a Scottish engineer. After one hundred year in 18 th century steam engine more developed and walk on way of water which is 1 st steamboat ride in world successfully. Following this 1807 Robert Fulton successfully developed a watt engine. In 19 th century Marine steam engine is more developed by scientist. And Marine Steam Engine divided by two method of manufacture number one is Cylinder technology and number two is connection mechanism. Some example of connection mechanism is crosshead, side lever, vibrating lever, vertical, oscillating, back acting, trunk, di
