Inversion of a kinematic linkage or mechanism is observing the motion of the members of the mechanism with fixing different links as reference frame. Each time when a different link is chose as the frame link the mechanism shows different characteristics of the motion.
Every machine is made to perform and produce some useful work. To make any machine work or to give output it needs to be actuated. Actuation of a mechanism or machine means to input mechanical work into it which is in turn transformed into the desired useful work output by the machine.
Degrees of Freedom of members and joints of mechanisms govern the working of a machine. Each member of mechanism can move in certain directions or rotate about certain axes and is not allowed to move or rotate in other directions. Degrees of Freedom determine the possible movements of mechanisms.
The members forming the mechanisms and machines are connected together through Kinematic Joints. The properties of joints such as relative motion and degrees of freedom determine the working of a machine. This article includes examples of different types of Kinematic Joints.
To obtain the desired motion of a machine, the design has to involve analysis beforehand. Read an introduction to the design of mechanisms by analysis and synthesis.
Machines as simple as livers, machines such as James Watt’s steam engine and the industrial robots such as PUMA all are composed of mechanisms whether simple, complex or combination of many simple and complex mechanisms. These mechanisms are governed by Kinematics – the study of geometry and motion.
Geothermal power plants are used for production of electricity from geothermal energy. The traditional thermal power plants need fuel for generating electricity while geothermal powre plants don’t need fuel. Here are some of the advantages of generating electricity from geothermal energy.
Do you know what a Gyroscope is? Do you know the Principle of Precession? A gyroscope Literally defies gravity and is based on the principles of Angular Momentum and this article just tells you how it works.
Wind turbines convert wind energy directly into electrical energy. Individual wind turbines can be installed for the domestic purpose, while for the commercial purposes a number of them can be installed in what is called wind farm or wind power plant.
We have been reading a lot about depleting reserves of oil and fossil fuel and the rising demand for energy with the ever growing development across the globe. Here are a few facts about this issue.
