1.	Consider two cylindrical rods of identicaly dimensions, one of rubber and the other steel. Both the rods are fixed rigidly at one end to the roof. A mass M is attached to each of the free ends at the centre of the rods. Then
Answer» Both the rods will elongate but there no PERCEPTIBLE change in the shape. The steel ROD will elongate and change shape but the rubber rod will only elongate. The steel rod will elongate without any perceptible change in shape, but the rubber rod will elongate and the shape of the bottom EDGE will change to an ellipse. The steel rod will elongate, without any perceptible change in shape, but the rubber rod will elongate with the shape of the bottom edge TAPERED to a tip at the centre. Answer :C
