A steel piano wire (Y = 200 GPa) has a diameter of 0.790 mm. At one end it is wrapped around a tuning pin of diameter 8.00 mm. The length of the wire (not including the wire wrapped around the tuning pin) is 66.0 cm. Initially, the tension in the wire is 381 N. To tune the wire, the tension must be increased to 413 N. Through what angle must the tuning pin be turned?

A steel piano wire (Y = 200 GPa) has a diameter of 0.780 mm. At one end it is wrapped around a tuning pin of diameter 8.00 mm. The length of the wire (not including the wire wrapped around the tuning pin) is 66.0 cm. Initially, the tension in the wire is 379 N. To tune the wire, the tension must be increased to 407 N. Through what angle must the tuning pin be turned? (θ = answer°)

A steel and aluminum wire, each of length L and diameter d, are joined to make a single wire of length 2L and diameter d. The wire is attached to fixed supports so that it is straight but with negligible tension. After being cooled by a change in T, the aluminum is found to have increased in length by 0.0140% (and the steel decreased in length by the same percentage.) If d = 1.00 mm, find: (a) the difference in...

A steel wire in a piano has a length of 0.5000 m and a mass of 4.200 10-3 kg. To what tension must this wire be stretched so that the fundamental vibration corresponds to middle C (fC = 261.6 Hz on the chromatic musical scale)? -------- Two pieces of steel wire with identical cross sections have lengths of L and 2L. The wires are each fixed at both ends and stretched so that the tension in the longer wire is...

An aluminum piano wire snapped in my prized grand piano. I found another one, but it was too short by 0.156 mm. The wire is 89.3 cm long and 2.6 mm in diameter. I decided to stretch it to fit by attaching a steel ball (density = 7860 kg/m3) with a radius of 3.0 cm and whirling it about in a vertical circle. What tangential velocity (in m/s) is needed at the top of the circle to stretch the wire...
