Students have asked these similar questions
Two wires are welded together end to end. The wires are made of the same material, but the diameter of one
is twice that of the other, di= 2 d2. They are subjected to a tension of T=4.60 N. The thin wire has a
length of L2 = 40.0 cm and a linear mass density of 2 = 2.00 g/m. The combination is fixed at both ends
and vibrated in such a way that two antinodes are present, with the node between them being right at the
weld.
(a) What is the frequency of vibration?
(b) What is the length of the thick wire, L1 =?
Solution:
A copper wire has a density of ρ = 8920 kg/m3, a radius of 1.20 mm, and a length L. The wire is held under a tension of 10.00 N. Transverse waves are sent down the wire. (a) What is the linear mass density of the wire? (b) What is the speed of the waves through the wire?
What is the fastest transverse wave that can be sent along a given wire? For safety reasons, the maximum tensile stress to which this
wire should be subjected is 5.28 × 108 N/m². The density of the wire is 8020 kg/m3. Note that your answer does not depend on the
diameter of the wire.

- (a) What is the fastest transverse wave that can be sent along a steel wire? For safety reasons, the maximum tensile stress to which steel wires should be subjected is 7.00 * 108 N/m2.The density of steel is 7800 kg/m3. (b) Does your answer depend on the diameter of the wire?arrow_forwardYou must determine the length of a long, thin wire that is suspended from the ceiling in the atrium of a tall building. A 2.00-cm-long piece of the wire is left over from its installation. Using an analytical balance, you determine that the mass of the spare piece is 14.5 mg. You then hang a 0.400 kg mass from the lower end of the long, suspended wire. When a small-amplitude transverse wave pulse is sent up that wire, sensors at both ends measure that it takes the wave pulse 26.7 ms to travel the length of the wire. (a) Use these measurements to calculate the length of the wire. Assume that the weight of the wire has a negligible effect on the speed of the transverse waves. (b) Discuss the accuracy of the approximation made in part (a).arrow_forwardA uniform cylindrical steel wire, 55.0 cm long and 1.14 mm in diameter, is fixed at both ends.

(b) What is the vibration frequency for this harmonic?arrow_forwardA wire of length L, = 30 cm has one end fixed and the other end welded to another wire, whose linear density of mass is 4 times smaller. The second wire passes through a pulley and a mass of 10 kg is suspended by its other end. The distance L2 between the weld point and the pulley is 80 cm. A stationary wave is produced in the composite wire, whose ends at the left wall and the pulley remain fixed.

(b) A 500.0 N ball now replaces the original ball. What is the change in the wavelength of the third harmonic caused by replacing the light ball with the heavy one?arrow_forwardYour answer is partially correct. A Tunable Inclined Plane. You and your team are designing a tunable, single-tone, acoustic emitter. One end of a string is connected to a post on the top of a frictionless inclined plane. The string supports a mass at rest below, on the surface of the plane. The angle of the incline relative to the horizontal (0) is adjustable. The length of the string is L = 34.0 cm, and the mass per unit length of the string is > = 5.58 x 10-³ kg/m.
