Refrigeration and Air- conditioning S ET-A
1. The resultant of two equal forces P making an angle 8, is given by:
(a) 2P sin (812) ( b) 2P tan (812) ( C) 2P cot (8/2) (d) 2Pcos(8/2)

2. A body weighs 98N on a spring balance on the north pole. The same body is shifted to
the equator, the weight of the body at the equator on the same scale is: (Assume g=9.8
m/sec2 and radius of the earth=6400 km)
(a) 97.45N (b) 98.66 N
(c) 97.66 N (d) 98.22N

3. A uniform heavy rod of weight W, cross-sectional area A and length L and having Young's I
I4 Modulus E is hanging vertically from a fixed support. Neglecting lateral contraction, the
elongation of the rod is given by:
1
(a) 5WL/3AE (bj 48WL/AE (c) WL/2AE (d) WLl(548AE)

4. Two barsBl and 82 of different materials and the same size are subjected to the same
I tensile force. If the bars have unit elongation in the ratio of 3:7 respectively, then the
ratio of modulus of elasticity of the two bars B1 and B2 will be:
(a) 3:7 (b) 7:3 (c) 3:4 (d) 4:3

5. The pressure at a point 6 m below the free surface of water is:
I
I (a) 58.86 kPa (b) 58.86 Pa (c) 58.86 bar (d) 58.86 MPa

6. A uniform body of 4 m long, 1 m wide and 1 m deep floats in water. If the depth of
immersion is 0.6 m, then the weight of the body is:
- - (a) 20.54 kN (b) 23.54 kN (c) 35.54 kN (d) 45.54 kN
