ME1232 – Kinematics of Machinery Two Mark Questions & Answers S4 Mechanical Engineering
KINEMATICS OF MACHINES (ME 1232) UNIT-1 SIMPLE MECHANISM. TWO MARKS :- Define 1)Kinematic Link 2)Kinematic pair 3)Kinematic c hain 4)Klein’s equation for joints 5)Degree of freedom of mechanism.6)Kutzbach’s relation 7)Grashoff’s law 8)Inversion of mechanism 9)Mechanical advantage of mechanism 10)Transmission angle? 1)Kinematic link It is a resistive body which go to make a part of a machine having relative motion between them. 2)Kinematic pair. When two links are in contact with each other it is known as a pair.If the pair makes constrain motion it is known as kinematic pair. 3)Kinematic chain. When a number of links connected in space make relative motion of any point on a link with respect to any other point on the other link follow a definite law it is known as kinematic chain. 4)Klein’s equation for joints. h-Higher pair joint l-Number of links j-Lower pair joint 5)Degree of freedom. Of mechanism. It is defined as the minimum number of input parameters which must be independently controlled inorder to bring the mechanism into a useful engineering purpose. 6)Kutzbach’s relation. n-Degree of freedom. l-Number of links. h-Higher pair joint j-Lower pair joint. 7)Grashoff’s law. Sum of shortest link length and sum of longest link length is not greater than the sum of remaining link length. 8)Inversion of mechanism. The method of obtaining different mechanism by fixing different links in a kinematic chain is known as inversion of mechanism. 9)Mechanical advantage of mechanism.
10)Transmission angle. 12)List out few types of rocking mechanism? Pendulam motion is called rocking mechanism. 14)Name the application of crank and slotted lever quick return motion mechanism?
