A 0.49-kg cord is stretched between two supports,7.3m apart. When one support is struck by a hammer, a transverse wave travels down the cord and reaches the other support in 0.83s .

 

What is the tension in the cord? (Express your answer to two significant figures and include the appropriate units.

Solutions

Expert Solution

v = distance / time = 7.3 m / 0.83 s

v = 8.79 m/s

T = (v^2)(m) / l

T = (8.79)^2 * (0.49 kg) / 7.3 m)

T = 5.19 N

A string is stretched between a fixed support and a pulley a distance 125 cm apart. The tension on the string is controlled by a weight hanging from the string below the pulley. An electomechnical vibrator is used to vibrate the string at 120 Hz. When the weight is adjusted to 275 g, the string is found to oscillate in its third standing wave mode (three loops). What is the speed of wave propogation on the string in this mode?...

Tendons are, essentially, elastic cords stretched between two fixed ends; as such, they can support standing waves. These resonances can be undesirable. The Achilles tendon connects the heel with a muscle in the calf. A woman has a 20-cm-long tendon with a cross-section area of 130 mm2 . The density of tendon tissue is 1100 kg/m3. For a reasonable tension of 500 N , what will be the fundamental resonant frequency of her Achilles tendon?
