In this course students will be able to learn about mechanism. The term mechanism is applied to the combination of geometrical bodies which constitute a machine or part of a machine. A mechanism may therefore be defined as a combination of rigid or resistant bodies, formed and connected so that they move with definite relative motions with respect to one another. The course is divided in to four sessions. In first session we will try to cover machines, mechanisms, difference between machines and mechanism, the difference between machine and mechanism is that machines transform energy to do work, while mechanisms so not necessarily perform this function. The term machinery generally means machines and mechanisms, discussion about general concepts of machine and mechanisms in daily life, their significance, what is the basics behind different machines in our day to day life.
A link is defined as a rigid body having two or more pairing elements which connect it to other bodies for the purpose of transmitting force or motion Rigid bodies, resistant bodies and difference between them, how these resistant bodies are used in mechanisms to from a machines. In second session we will try to cover Kinematic link and its used in case of mechanism.
Also we will discussed detail classification of Kinematic pair based on certain criteria. In third session we will try to cover different types of constrained motion along with example and its used in mechanism and in fourth session we will try to relevance of degree of freedom in mechanism.
The degrees of freedom (DOF) of a rigid body is defined as the number of independent movements, To determine the DOF of this body we must consider how many distinct ways the bar can be moved. In a two dimensional plane such as this computer screen, there are 3 DOF. The bar can be translated along the x axis, translated along the y axis, and rotated about its centroid. it has Instructor will be discuss the things in details in very easy manner. This course will help the students to learns the basics of mechanisms, its uses, definition of different terms used in mechanisms.
