Dear Students,
At this time you might have prepared the important quesstions. Today evening revise all prepared chapters first and then only go for new things, if time peermits. Also prepare similar numerical questions to thge questions, which I have solved and posted on blog/ mailed. Don't be nurvous and
utilise every minute left. My good wishes are always with you all.
Most important are:
Manufacturing system....posted on blog.....Charts with other auxiliary systems & services as I explained.......Lathe, Milling Differance between shaper and planer, shaper and slotter
What is the machine, parts, figure, opeerations uses and safety of machines....Lathe, Milling and shaper.
NC and CNC.....Differance, Basic components..Part program. machine control unit (MCU)..Programs based on mediums, control systems advantages of NC & CNC.
Thermodynamics: What is? Laws, Joules Wheel Experiment for 1st law , Kelvin Plank and Clausius Statements. Zeroth Law. Enthalpy, Internal Energy and Entropy as I dictated. Explain constant volume. constant pressure, Isothermal and Adiabatic processes. Heat, Work and Pressures....Absolute, atmosphere and gauge..
Steam: Properties, Types (Wet, Dry, Saturated and Superheated) Chart at stages... Dryness fraction, Calorimetres..Throtlling and separating...Enthapy of steam, sp. vol. of steam, IE of steam and Entropy of steam. Mollier Diagram..Study Boilers(Complete) as explained in Lab.
Refrigeration &bAir Conditioning: Definition in BLOG..same to same.Human comforts, Ratinf TR, COP,
SVCR cycle/ system..... HE, REFRIGERATOR and HEAT PUMP.....p-h chart...critical point and tripple point....refrigerants...psychrometry chart....Humidity and degree of saturation.
Hydraulic machines and pumps: Fluid machines, Hydraulic machines, Hydralic turbines Types,
...construction and working of all 3 turbines in course Types of pumps construction and working of centrifugal and reciprocating turbines FIGURES...Priming and methods. Impellors and HUB.
Power Transmission: Types & methods of power transmission....Belt, Rope ,Chain and Gear drives
Gear Trains VRs in all ...length of belt.....Nnumerical of gear and belt....What is cluth types and single plate Multiple plate clutch.
Stress and Strain: What is load, All types of stresses and strains all as dictated...Young Modulus, Modulus of rigidity, Bulk Modulus Poissons Ratio etc complete what ever taught with Numerical...Relation in elastic constants E, G, K.... Beam and Tortion as dictated in class.
BEST of LUCK
