Задача 30891.

A running longitudinal wave from a source propagates in a steel rod, the equation of oscillations of which is given in the form: x = 10 ^ -5 * sin10 ^ 2 * t, m. Young´s modulus of steel 2 * 10 ^ 11 N / m; steel density 8 * 10 ^ 3 kg / m ^ 3. Write the wave equation. Determine: wavelength; maximum relative deformation in the rod.

Detailed solution with a brief record of the conditions, formulas and laws used in the decision, the conclusion of the calculation formula and the answer.
If you have any questions about the decision, write. I will try to help.
