A wire of unknown material with a cross-sectional area of 1 mm^2 and an unstretched length of 0.5 m is stretched through the application of known forces. From the plot of force as a function of Delta L in the figure, the Young's modulus of the material is: A. 4 times 10^10 N/m^2 B. 80 N/m^2 C. 40 N/m^2 D. 8 times 10^10 N/m^2 E. none of the above
Please answer #5. Show all work.
. A 10 kg load suspended by a brass wire 10 m long is observed to vibrate vertically in SHM at a frequency of 10 vibs. Given that the Young's modulus for brass is 9x 1010 N/m', what is the cross-sectional area of the wire?
A 107 kg mass suspended from a wire whose unstretched length is 4.05 m is found to stretch the wire by 6.40 mm . The wire has a uniform cross-sectional area of 0.130 cm2. a) If the load is pulled down a small additional distance and released, find the frequency at which it vibrates (in Hz). b) Compute Young's modulus for the wire.
A sample of collagen fiber with a cross-sectional area of 1.2*10^−7 m^2 is hung from a fixed support, and a gradually increasing load is applied to the lower end. The tensile strength of collagen (i.e. its fracture stress) is 0.6*10^8 N/m^2. Estimate the load in kilograms that can be applied before the fiber breaks we probably use the equation for breaking stress: Force(max)/Area = Y(max change in length) / length
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...
1. A wire of length L and cross-sectional area A has a resistance of 5 Ω. What is the resistance if the same amount of material is used to make a wire triple as long? 2. What is the resistance of 15 m length of household no. 14 copper circular wire having a diameter of 1.6 mm? (Hint: the resistivity of copper – textbook, page 782)
