- One end of a piano wire is wrapped around a cylindrical tuning peg and the other end is fixed in place. The tuning peg is turned so as to stretch the wire. The piano wire is made from steel (Y = 2.0x1011 N/m2). It has a radius of 0.75 mm and an unstrained length of 0.96 m. The radius of the tuning peg is 1.6 mm. Initially, there is no tension in the wire, but when the tuning peg is turned, tension develops. Find the tension in the wire when the tuning peg is turned through two revolutions.A piece of steel piano wire is 1.3 m long and has a diameter of 0.60 cm. If the ultimate strength of steel is 5.0 × 108 N/m?, what is the magnitude of tension T required to break the wire? T =A force stretches a (first) wire by 2mm. This wire is made of an unknown material and has a 1.2cm diameter and 3.5cm length. A second wire of the same material has the same length but four times the diameteras the first. How far will it be stretched by the same force?
