Sir Tom se question tha .. Agar 5 link hai to DOF 3 hai aur 3 joint hai to DOF 2 hai to DOF 1 ke liye number of pairs kitna hoga . Sir Vibration se question tha Do mass M and 2M ek spring se connect hai to Time period kitna hoga . RAC SE question tha . T-S diagram diya tha usme process poocha tha jaise isobaric isochoric isothermal aur isentropic.. Maths me . Eigen value se question tha . P-V diagram diya tha aur T-S poocha tha

BARC MEMORY BASED QUESTION

BARC question

Hello sir, Good morning Yesterday BARC Question Thermo - first law , unsteady (exit from tank) , 2nd law (COP problem) Industrial - forcasting ( exponential smoothning method), Quing theory, PERT-CPM, EOQ pucha tha., LPP one graphical method question very easy,Question are ESE level Maths - Matrices ( cailey hamilton theorem) , Probability ( two coin tossed) , Calculus ( area under curve) Production - spru design, flame type ( netral, oxidizing ...), solidification. SOM - elongation calculation , reaction force calculation under UDL, strain energy. Abhi to itna hi recall kr paa reha hu sir , or yaad aayega to message karunga. 🙏 Thank you sir your concepts helps a lot 💐.
