Theory of machine| part -1

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

Difference between heat and work, Thermodynamics 1st law,Difference between heat and temperature.

             THERMODYNAMIC

Difference between heat and work?

work- work is a mode of transition of energy.
Heat - Heat is work.
we get,Heat is work & work is heat.
       1.Heat and work not storing them.
       2.Heat and work is not an energy.
       3.heat and work is way of energy                gains and loss.
       4.once energy gains and loss,object cannot difference,which energy comes from heat or work.

1st law of thermodynamic:It concern the principle of conversation of energy,According to energy cannot created or destroyed,it only changes one from to another from.Total energy remain constant.

        According to law,ΔE = Q—W
             ΔE = change of energy of the system.
Q = Heat flow of into the system.
W= Work done by the system.

Difference between heat and temperature?
Heat -mode of transmit of energy.
In microscopic level,heat is disoder to motion.
Temperature - Temperature is a average of kinetic energy particle of the body.[microscopic level]
           
we shown in this pic, K.E (avg) A > K.E(avg) B.
Total energy(A) < Total enenergy (B).
We get the conclusion,pot B larger than the pot A.so,total energy always grater B.
     Here,we want to energy increase pot A,heat A,there total energyenergy will increase.

I.C engine - two stroke cycle - four stroke cycle - difference between two stroke four stroke - auto ignition -carburetion - scavenging -supercharging

                              I.C ENGINE Difference of petrol and diesel engine :- 1.Petrol engine run on otto cycle and diesel engine run on diesel cycle. 2.Air fuel mixture suction Stroke in petrol engine.In diesel engine only air sucks in suction stroke. 3.In petrol engine,spark plug is needed.In diesel engine,no spark plug is needed. 4.In petrol engine,compression ratio 6-12. In diesel engine,compression ratio 14-22. 5.In petrol engine,high efficiency. In diesel engine low efficiency. 6.In petrol engine,less vibration & noise. In diesel engine,more vibration & noise. 7.Petrol engine light weight engine. Diesel engine heavy weight engine. 8.Petrol engine generaly use motor cycle,car,light weight vehicles. Diesel engine generaly use truck,bus etc.    GOVERNINNG OF I.C ENGINES : Various methods are : a. Heat and miss governing — used for small engine,No fuel admited during t...

Thermodynamic process,zeroth law

          THERMODYNAMIC Process, when sytem's property has any change,it call process. Reversible process, In this process,system and surrounding returns on their originaloriginal states.                   In actual practice,all process are irreversible. Cyclic process, The system after undergoing a series of process returns to its originaloriginal condition.                   Quasi-static processprocess, In every intermediate that achive in equilibrium and process infinitesimally and slowly.               Adiabatic process, which there is no flow of heat between system and surroundings.           Zeroth law of thermodynamics, states that when any two bodies are in thermal equilibrium with third,there allbody in thermalthermal equilibrium .            ...
