JNTUK B.Tech Mechanisms and Mechanical Design gives you detail information of Mechanisms and Mechanical Design R13 syllabus It will be help full to understand you complete curriculum of the year.
UNIT – I : MECHANISMS: Elements of links – Classification – Rigid link, flexible and fluid link – Types of kinematic pairs – Sliding, turning, rolling,screw and spherical pairs – Lower ad higher pairs – Closed and open pairs – Constrained motion – Completely, partiallyor successfully constrained and incompletely constrained.
MACHINES: Mechanism and machines – Classification of machines – Kinematic chain – Inversion of mechanism – Inversion of quadratic cycle, Chain – single and double slider crank chains. Exact and approximate Straight line Mechanisms – Peaucellier, Hart T. Chebibheff , Pantograph.
UNIT – II: KINEMATICS: Velocity and acceleration – Motion of link in machine – Determination of velocity and acceleration diagrams – Graphical method – Application of relative velocity method four bar chain.
ANALYSIS OF MECHANISMS: Analysis of slider crank chain for displacement, Velocity and acceleration of sliding – Acceleration diagram for a given mechanism, Kleins construction, Coriolis acceleration, Determination of Coriolis component of acceleration.
UNIT – III : PLANE MOTION OF BODY: Instantaneous center of rotation, centroids and axodes – Relative motion between two bodies – Three centers in line theorem – Graphical determination of instantaneous center, diagrams for simple mechanisms and determination of angular velocity of points and links. Precission: Effect of Precission on Stability of moving vehicles such as motorcar motorcycle Aero planes and ships. Static and Dynamic forces generated due to in Precision in moving mechanisms including Gyroscopic motions.
UNIT – V : CAMS: Definition of cam and followers – Their uses – Types of followers and cams – Terminology – Types of follower motion – Uniform velocity – Simple harmonic motion and uniform acceleration. Maximum velocity and Maximum acceleration during out ward and return strokes in all the above three cases.
