Stress-Strain Problems and solutions: A wire of length 2.50 m has a per- centage strain of 0.012% when loaded with a tensile force. Determine the extension of the wire. Solution: Original length of wire = 2.50 m = 2500 mm and strain = 0.012 100 = 0.00012 Strain ε = extension/originallength =x/L, extension x = …
UNITS AND DIMENSIONS: Units and Dimensions are used to represent the standard form of measurements for an object or a body. They are used for enhance the characteristics such as Area, Volume, Force, Density, Energy etc.of different objects in different fields. Dimensions: A dimension is a word which is used to describes the measurable characteristics …
Difference between solids and fluids: Solids and fluids are the arrangements of molecules in different patterns. This particular arrangement of molecules is different from each other. In solids, the molecules are arranged in a close and very near to each other there is no gap or space in between solid molecules. With this type of …
Difference between static balancing and dynamic balancing: Static Balancing: Static balancing is considered and applied only when the system of masses revolves in one plane. When the centre of the system acts on the axis of rotation then the system is under static balancing. This type of balancing system is used for small and medium …

Types of stresses: In this article, we are going to learn different types of stresses, generally stress is caused due to some force acting on the object, different types of stress depends upon the force acting on the object. there are two types of stresses. 1) Internal Stress. 2) External Stress. Internal Stress: Internal stress …
Basic Definitions used in engine terminology: Bore: The inner diameter of the cylinder is called a bore. Stroke: Stroke is the length of the piston moves from the bottom of the cylinder to the top of the cylinder is known as a stroke. Clearance Volume: The clearance volume is the space between the top of …

Difference between SI Engine and CI Engine: SI and CI Engines are used to generate heat energy and further heat is converted into mechanical energy to run the vehicle. SI engine required a spark plug to ignite the air-fuel mixture. but in CI engine it ignites the air-fuel mixture with the help of high compression …
Common rail direct injection system (CRDI): Common rail direct injection system is mostly used in modern diesel engines. In this type of injection system, the fuel is supplied to the injectors with the required pressure and further supplied to the cylinders for the combustion process. By using a common rail direct injection system the required …
