Whenever a machine component such as a shaft or structure is under loaded condition a complex stress is generated in its material. The machine Designer has to take care of the weakest part or portion, the maximum possible stress condition, or other practical factors for the component to survive under load conditions. It is critical […]

Mechanical power press works on the principle of slider crank mechanism or modified mechanisms such as Kuncle joint or linkage drive. The tonnage of the press (pressing force) is required before the slide reaches the bottom dead center (BDC). The reason is that the metal sheet has some thickness and forming force should be transferred

Introduction The power generation industry can be regarded as the cornerstone of modern civilization. Modern power generation takes a variety of forms as will be seen in the below article. It will be evident that the magnitude of this industry is such that one article cannot cover all of its details. The top 10 electricity
Introduction Power Screws are one of the common machine elements used in various applications that require converting the rotating motion (Torque input) into a linear motion (Force output). The best example of a power screw is the Lifting Jack used for changing the car wheel. Power Screws are also called lead screws and are used

Drive System of a Railway Locomotive All modern Electric & Diesel locomotives are hauled by traction motors. An electric locomotive is powered by electricity from overhead high-tension (voltage) electric lines through pantographs and transformers. In contrast, diesel locomotive has Traction Alternator connected to the engine & electricity generated by the alternator is used to power

What is a compressor? As we know liquids are incompressible (theoretically) whereas gases or air can be compressed to a desired pressure (above atmospheric pressure). Practically, Gases can not be used for engineering purposes (such as in industrial pneumatic systems, blowers, household gas supply for heating, hospital oxygen supply systems, air-conditioning, etc.) at atmospheric pressure.
