Kinematics links - Every part of machine which have relative motion to another part. → The link should be resistance body. What is resistant body? →Under the action of force it can transfer motion and power. Kinematics links →1. Rigid links 2. Flexible links 3. Fluid links Rigid links - There is no deformation. Ex - piston,connecting rod Flexible links - Deformation is allowed under permissible limits. Ex - Belt drive Fluid links - A fluid link is one that is deformed by having fluid in a closed vessel and the motion is transmitted through the fluid by pressure. Ex - Hydraulic press Types of links - 1. Singular 2. Binary 3. Ternary 4. Quaternary links
THERMODYNAMIC
Provide a single word for following statements.

2.Any observable characteristc of the system. (Property)
3.Any change of state occuring in a system.(process)
4.An enclosure which permits thermal interaction.(diathermic)
5.A quantity of matter of fixed mass and identity which is bounded by closed surface.(system)
6.A region of interest,that is involved in an analysis.(system)
7.A change in the state of the system which occurs without any work being done.(free motion)
8.Two state of two system charecterised by an absense of heat flow when there is a no adiabetic wall between them.(tharmal equilibrium)
9.The loci of points corresponding to state of the same temperature.(isotherms)
10.A process in which all thermodynamic properties are the same at the start and at the end of the process.(cyclic process)
11.A process which fluid expands without doing any work.(throttling)

24.A process in which the heat transfer is equal to change in enthalpy.(isobaric process)
25.Internal energy change of an ideal gas is proportional Cv.
