Since the invention of computers or machines, their capability to perform various tasks went on growing exponentially. Humans have developed the power of computer systems in terms of their diverse working domains, their increasing speed, and reducing size with respect to time. A branch of Computer Science named  Artificial Intelligence  pursues creating the computers or machines as intelligent as human beings. What is Artificial Intelligence? According to the father of Artificial Intelligence, John McCarthy, it is  “The science and engineering of making intelligent machines, especially intelligent computer programs”. Artificial Intelligence is a way of  making a computer, a computer-controlled robot, or a software think intelligently , in the similar manner the intelligent humans think. AI is accomplished by studying how human brain thinks, and how humans learn, decide, and work while trying to solve a problem, and then using the outcomes of this study as...

Mechanics: It is that branch of scientific analysis which deals with motion, time and force.  Kinematics is the study of motion, without considering the forces which produce that motion.  Kinematics of machines deals with the study of the relative motion of machine parts. It involves the study of position, displacement, velocity and acceleration of machine parts.  Dynamics of machines involves the study of forces acting on the machine parts and the motions resulting from these forces.  Plane motion: A body has plane motion, if all its points move in planes which are parallel to some reference plane. A body with plane motion will have only three degrees of freedom. I.e., linear along two axes parallel to the reference plane and rotational/angular about the axis perpendicular to the reference plane. (eg. linear along X and Z and rotational about Y.)The reference plane is called plane of motion.  Plane motion can be of three types. 1) Translatio...

If the frequency of oscillation on earth is n then the frequency of oscillation on the moon will be n/√6. The biflar suspension method is used to find out moment of inertia. The total number of instantaneous centers for a mechanism of n link is equal to n(n-1)/2. In case of an elliptical trammel two pairs turn and two pairs slide. A shaft revolving in a bearing forms a lower pair. For kinematic chains formed by lower pair the relation between the number of link L and the number of joint J is given by L = 2/3 (J+2). The mechanism used to enlarge or reduce moments for reproducing drawings to different scales is called pantograph. The number of links in a pantograph is to 4. If a practical of a link has a velocity that changes both in magnitude and direction at any instant, then it must have two components of acceleration e.g., centripetal. And tangential. The Klein’s method of construction for reciprocating engine mechanism utilities a quadrilateral similar to...
