1. A length of nylon fishing line of 2 mm diameter is tied to a length of 0.5 mm diameter stainless steel wire, then stretched between two rigid supports 2 m apart such that the tension in the wires is 20 N and the connection point between the two wires is exactly midway between the posts. The air temperature then goes down by 20°C. Find the distance that the connection moves. [Youngs modulus for nylon is 3 GPa, its thermal expansion coefficient is 6×10-5/K. Youngs modulus for stainless steel is 180 GPa, its thermal expansion coefficient is 1.7 x 10-5/K.]
