A tension FT is applied to a wire with mass per unit length μ and length L. When struck, it vibrates at its fundamental frequency f1. The wire is then removed and stretched to twice its original length 2L. If the same tension is applied to the stretched wire, what will be its new fundamental frequency?

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...

Question 4 1 pts A wire made from a composite material is shaped into a cylinder and is stretched by a machine pulling in opposite directions at the two ends of the wire. The wire has an initial length of 1.20 m and an initial cross-sectional area of 9.00 x 10-6m2. If a force of 450 N stretches it by 2.1 mm and the wire returns to its original shape after being stretched, what is the Young's Modulus of the...

You are working at a company that manufactures electrical wire. Gold is the most ductile of all metals: it can be stretched into incredibly long, thin wires. The company has developed a new technique that will stretch 1.00 g of gold into a wire of length L= 2.40 km and uniform diameter. a) What is 1 gm in kg, and what is the volume of 1 gm of gold? The mass density of gold ρ= 1.93 x 10^4 kg/m3. Watch...

Question 1. What does the slope of the plot of tension
force vs. position represent?
Question 2. For the second run, do you notice nonlinear
behavior at high tension forces? Does this indicate the material is
becoming stiffer or slinkier?
Question 3. What does the trend in the graph indicate
will happen if you keep adding even more tension to the
wire?
Question 4. For a wire that has twice the radius of our
wire, how much would it stretch...
