Hi Friends, According to me, the changes required in the TRB tentaive key are as follows. I have collected the proofs for the questions mentioned below. 1)Virtual Work refers to Virtual work done by actual forces. 2) Coefficient of linear expansion of steel and Al-all the given options are wrong. 3)For winter air conditioning relative humidity should not exceed 60%. 4)In vapour compression refrigeration system the condition of refrigerant before entering the compressor is dry saturated vapour. 5)DNC system does not require a dedicated computer.It requires a central computer.(CNC system only requires a dedicated computer). So the correct option will be B) (b) and (c). 6)For the heat distribution question the correct answer is d)chip,tool,work, environment. 7)Lami's theorem is applicable only for coplanar and concurrent forces. 8)A bore of 14.46 mm diameter can be measured by Vernier caliper as well as micrometer(I don't have exact proof but according to the details from book, micrometer is easier to record and accurate than vernier caliper.If vernier can measure 14.46 mm micrometer can measure the same value easily and also LC of Micrometer is 0.01mm and vernier is 0.02 mm) So answer should be either vernier caliper or micrometer. 9)dQ=du+pdv is applicable only for a reversible process.So no options are correct. 10)For a SSB max deflection at midspan is 5mgl^4/384EI. 11)In a parallel flow heat exchanger if NTU is 2.5 lowest possible effectiveness will be 50%. 12)For a reheat rankine cycle all the given options are correct.
