May tanong na ganito yung mga choices, read niyo nalang meaning ng mga to. A. Marination B. Emulsification C. Colloids  D. Nakalimutan ko isa. Haha 38. Isang tanong about sa thermal relay, ano daw purpose nun? Basta natatandaan ko sa mga choices eto: A. Prevent fire B. Prevent short circuit C. Prevent ground 39. May tanong sa refrigeration na ito mga choices, basta read niyo nalang meaning at purpose ng mga to sa refrigeration cycle. A. Evaporator B. Compressor C. Condenser D. Exhaust 40.

What is the input current to a 5 hp single phase electric motor use to drive a hammer mill at 2200 rpm. The input voltage is 220 volt. Assume a power factor of 0.98. A. 14.5 amp B. 17.3 amp C. 20.4 amp D. None of the above 42. Recommended orientation of swine house A. North-south direction B. East-west direction C. North-west direction D. South-east direction 43. May tanong about sa illumination, base sa natatandaan ko, given yung lighting intensity ng fluorescent lamp then yung lamp is 4 meters from ground, then may table na 2 meters ang height na may paper sa taas ng table. Ano daw ang illumination sa center ng paper? (Read and read lang preferably sa mga UP Reviewers okay?)  44. Computations of Torsional Stress using the formula: Stress = 16T/pi D3 45. Computations about Deflection. 46. Computations about Mount height (Nung exam ko lang naencounter yan). 47. Computations about Synchronous Motor (Yung formula nasa AgEng Formula ni Engr. Belonio) 48. Computations using the formula MC DELTA T (Practice). 2 problems dito. 49. Computations using Ohm’s Law basta alam lang ang mga theories sa Series at Parallel, DC Circuit and AC Circuit. Believe me, mas madali ang mga computations sa rural electrification basta alam lang ang mga basics.  50. Computations about Thermodynamics, Heat Transfer (Conduction, Convection, Radiation, Emissivity), Ideal Gas Law, Charle’s Law at Boyle’s Law. Nasa 30 % yata ng exam ng AREA 3 ang tungkol dito. Medyo naloka ako sa AREA na to kaya practice lang sa pagsosolve. Haha.
