A graphene rod and a brass rod have the same length and diameter and are subjected to the same force. If the graphene rod stretches by 2.60X 10^-6 m, by what amount will the brass rod stretch? Young's modulus for graphene = 1.00x 10^12 N/m2; for brass = 9.00X 10^10 N/m2.
A spider of mass 6.9 x 104 kg hangs from a 78.1-cm-long thread whose diameter is 2.0 x 10 mm. Young's modulus of thread is 3 x 10° N/m2. By how much does the thread stretch?
4. Hanging by a Thread (2 pts). A spider spins a fine thread of spider silk between two posts a distance L0 apart. The thread has a diameter of d = 5 × 10-6 m and an equilibrium length of L0. When the spider (with mass m = 2 milligram) hangs from the center of the thread, the thread sags and stretches to support the weight of the spider, making an angle of θ = 10° below the horizontal, as...
can be represented by a uniform rod 38.0 cm in length and 2.10 cm in radius. Assume Young's modulus for bone under compression is 9 x 10 N/m2 rod and a steel rod have the same length and diameter and are steel rod stretch? Young's modulus for graphene 1.00 x 1012 N/m2; for steel- 2.00 x101 N/m2 2
An orb weaver spider with a mass of 0.23 grams hangs vertically by one of its threads. The thread has a Young's modulus of 4.7 x 109 N/m2 and a radius of 9.8 x 10-6 m. 1) What is the fractional increase in the thread's length caused by the spider? fs = 2) Suppose a 73 kg person hangs vertically from a nylon rope. What radius must the rope have if its fractional increase in length is to be the...
2) A light bulb filament is made of tungsten. It has a cross sectional area of 1.7 x 10-m and a length of 0.02 m. What tension force should you apply to the filament to stretch it by the diameter of 1 tungsten atom, which is 2.1 x 10-10 m? The Young's modulus for tungsten is 3.6 x 1011 N/m² (4 points)

5. A metal wire is 2.5 mm diameter and 2 m long. A force of 12 N is applied to it and it stretches 0.3 mm. Assume the material is elastic. Determine the stress in the wire σ, the strain in the wire ε, and Young's modulus for the wire material.
Due to the operational conditions and temperature gradient, a 95 mm diameter, 1.75 m long steel rod within a machine assembly is subjected to a combination of tensile loading of 190 N and thermal loading which imposes a longitudinal force of 244 N. The total loading results in an even distribution of forces on the body of the rod causing it to change its dimensions by increasing 0.45 mm in length at both ends and decreasing by 0.0135 mm at...
