Figure < 1 of 1 Consider, for instance, a bar of initial length L and cross-sectional area A stressed by a force of magnitude F. As a result, the bar stretches by AL (Figure 1) Let us define two new terms: • Tensile stress is the ratio of the stretching force to the cross-sectional area: stress = 5 • Tensile strain is the ratio of the elongation of the rod to the initial length of the bar strain= 41 It...

A steel wire of cross-sectional area 2.9×10−4 m^2 is under a tension of 1×103 N. At what speed does a transverse wave move along the wire? The density of steel is 7,860 kg/m^3.
A guitar string of length L = 0.79 m is oriented along the x-direction and under a tension of T = 110 N. The string is made of steel which has a density of ρ = 7800 kg / m3. The radius of the string is r = 8.9 x 10-4 m. A transverse wave of amplitude A = 0.0020 m is formed on the string. a) Calculate the mass per unit length μ of the guitar string in kg/m....
