question 15

Short Answer

An aluminum wire and a steel wire,each of length 2.0 m,are hung from the ceiling.A 5.0-kg mass is suspended from the lower end of each wire.The aluminum wire has a diameter of 2.2 mm.What must be the diameter of the steel wire if it is to stretch the same distance as the aluminum wire,so that the two wires maintain equal lengths after the masses are attached? Young's modulus for aluminum is 0.70 × 10¹¹ N/m² and for steel it is 2.0 × 10¹¹ N/m².
