Smart Materials

In certain respects, smart materials are an answer to many contemporary problems. In a world of diminishing resources, they promise increased sustainability of goods through improved efficiency and preventive maintenance. In a world of health and safety threats, they offer early detection, automated diagnosis, and even self-repair. In a world of political terrorism, they may offer sophisticated biowarfare countermeasures, or provide targeted scanning and intelligence- gathering in particularly sensitive environments. In general, smart materials come in three distinct flavors: passively smart materials that respond directly and uniformly ......... >>>>Read More

Ultrasonic Metal Welding

The ultrasonic effect upon the molten metal generates a smaller grain size, giving the metal more strength. Ultrasonic welding combines pressure and high frequency vibration motions to form a solid state bond. The range ultrasonic frequency used in this welding is from 20kHz to 60kHz. This cool, strong weld capable of joining such combination as aluminium to steel, aluminium to tungsten, aluminium to molybdenum and nickel to brass. Ultrasonic welding has also made it possible to join metals with vastly different melting temperatures, making strong rigid joints. Thus many applications ......... >>>>Read More

Transit Mixer & Concrete Pump

The transit mixer and concrete pumps are the delivery units of a RMC plant. The transit mixer used to deliver the RMC of same workability and quality at work site and the concrete pump is used to deliver the RMC at the desired place as per requirements. Before discussing about Transit mixer and concrete pump, must discuss about the significance of RMC The mechanisms of deterioration of concrete due to various physical, chemical, biological and environmental pollutants are widely researched. In search of possible reasons of non performance of concrete on the face......... >>>>Read More

Turbofan Engine

Jet Propulsion is the thrust imparting forward motion to an object, as a reaction to the rearward expulsion of a high-velocity liquid or gaseous stream.A simple example of jet propulsion is the motion of an inflated balloon when the air is suddenly discharged. While the opening is held closed, the air pressure within the balloon is equal in all directions; when the stem is released, the internal pressure is less at the open end than at the opposite end, causing the balloon to dart forward. Not the pressure of the escaping air pushing against the outside atmosphere but the difference between high......... >>>>Read More
