| Kiran Chandar | Re: Junior Engineer Mechanical Model question paper As per your request here I am sharing the SSC Junior Engineer Mechanical Model question paper: 1 Stokes theorem connects A) a line integral and a surface integral B) a surface integral and a volume integral C) a line integral and a volume integral D) gradient of a function and its surface integral Answer : (A) 2 A solar collector receiving solar radiation at the rate of 0.6 k W/m2 transforms it to the internal energy of a fluid at an overall efficiency of 50%. The fluid heated to 350 K is used to run a heat engine which rejects heat at 313 K. If the heat engine is to deliver 2.5 kW power, the minimum area of the solar collector required would be A) 8.33m2 B) 16.66m2 C) 39.68m2 D) 79.36m2 Answer : (D) 3 When the temperature of a solid metal increases, A) strength of the metal decreaes but ductility increases B) both strength and ductility of the metal decrease C) both strength and ductility of the metal increase D) strength of the metal increases but ductility decreases Answer : (A) 4 A company produces two types of toys: P and Q. Production time of Q is twice that of P and the company has a maximum of 2000 time units per day. The supply of raw material is just sufficient to produce 1500 toys (of any type) per day. Toy type Q requires an electric switch which is available @ 600 pieces per day only. The company makes a profit of Rs. 3 and Rs. 5 on type P and Q respectively. For maximization of profits, the daily production quantities of P and Q toys should respectively be A) 100, 500 B) 500, 1000 C) 800, 600 D) 1000, 1000 Answer : (C)    |
