The eigen values of symmetric matrix are all (A) Complex with non-zero positive imaginary part (B) Complex with non-zero negative imaginary part (C) Real (D) Pure imaginary Answer: (C) 5. The threaded bolts A and B of same material and length are subjected to identical tensile load. If the elastic strain energy stored in bolt A is 4 times that of the bolt B and the mean diameter of bolt A is 12mm, the mean diameter of bolt B in mm is (A) 16 (B) 24 (C) 36 (D) 48 8. The pressure, dry bulb temperature, and relative humidity of air in a room are 1bar, 30ºC and 70% respectively. If the saturated steam pressure at 30ºC is 4.25kPa, the specific humidity of the room air in kg water vapour / kg dry air is (A) 0.0083 (B) 0.0101 (C) 0.0191 (D) 0.0232 Answer: (C) 10.
