Aapproximate straight line mechanisms: This approximate straight line mechanisms are the modification of four bar chain mechanisms. They are explained as follows: 1.Watt’s mechanism 2.Grasshopper mechanism 3.Tchebicheff’s mechanism 1. Watt’s mechanism: It is used for early steam engines to set the piston rod in a cylinder to get a straight line motion approximate, this is …
Screw Jack: The screw jack is a device used for lifting heavy/huge loads, When we apply a smaller amount of effort on the handle to rotate the screw, this rotation used to move the rod in and out of the screw jack. this process is worked on the principle called inclined plane.as shown in figure …
Inversions of single Slider Crank shaft The single Slider Crank Chain is a four link mechanism. this is used for converting the circular rotation of crank link into straight line motion of piston rod in a cylinder. As we know that by fixing , turning etc.. With the help of different links in a kinematic …
Inversion Of Four Bar Chain Inversion of four bar chain: In this article we will learn about Inversion of four bar chain. There are many Different types of inversions of the four bar chain, the detailed explanation about Inversion of four bar chain is explained as Follows.Four bar chain mechanism is the simplest than many other …
Mounting of a grinding wheel Mounting of a grinding wheel & precautions to be observed during mounting can be explained as follows: Grinding wheel mountings are the most important principle/standard one, this gives protection when there is any misalignment in it. This wheel is used to run with high speed, so it should handle carefully. …
Explain Factors affecting the wheel selection 1. Operation condition. 2. Surface finishing. 3. Wheel speed. 4. Area of contact. 5. Severities of grinding operations.
cutting action of grinding wheel Grinding wheel cutting action is done by different types of particles called abrasive particles like granite, bonding materials etc.. When the wheel rotates this particles used to comes in contact with the work piece and removes the metal from work. some of the important thing in this grinding wheel is, …
Real gas: *It obeys Wander wall’s equation and other gas laws only under low pressure and high pressure *Temperature condition all these gases are real *It posses mass volume and velocity
About perfect gas: *Perfect gas obeys an ideal equation of gas and another gas law under all conditions of temperature and pressure. *These gases are does not exist and imaginary *It only posses mass and velocity *It does not have any potential electronic interaction
Perfect Gas laws: There are three different types of Perfect Gas laws, they are as follows 1.Boyle’s law 2.Charles law 3.Gay lussac’s law 1.Boyle’s law: Boyles law states that absolute pressure when temperature is constant this is called Boyle’s law.
