What is the maximum load that could be suspended from a copper wire of length 1.00 m and radius 1.08 mm without permanently deforming the wire? Copper has an elastic limit of 200 MPa and a tensile strength of 400 MPa. N

A force stretches a wire by 1.0 mm.a. A second wire of the same material has the same cross section and twice the length. How far will it be stretched by the same force?b. A third wire of the same material has the same length and twice the diameter as the first. How far will it be stretched by the same force?

Assume a person's mass is 62.0 kg and each of her shoes has an area of 220 cm2. F What is the compressive stress on her feet if her weight is A F spread out evenly over both soles of her shoes? 13.82 Ра A By what factor f does the compressive stress change if only 10.0 cm? of each shoe is in contact with the floor (as might be f = the case for high-heeled shoes)? * TOOLS x10

Which of the following statements is FALSE regarding materials experiencing stress within the proportional limit? O The object starts to fracture due to the large stress magnitudes. O The slope of the stress vs. strain curve is the elastic modulus. O The graph of stress vs. strain is steep; large stress values produce relatively small strain. O The material returns to its initial state when the stress is removed.

A 1.25 m long cable has a diameter 3.50 mm with a Young's Modulus, E, of 9.75 x 109 N/m2. When the wire is placed under tension, it experiences a stress of 202.52 x 106 N/m2, the length of the cable extends by 36.35 mm. Calculate the force that the cable experiences under tension and the strain energy density (UV) due to deformation. Give your answers in newtons (N) to 2 decimal places for the force; and in joules per cubic metre (J/m³) for the strain energy density to 2 decimal places. Assume the cable is solid and the material is homogeneous

*69. ssm A 1.0 × 10-3-kg spider is hanging vertically by a thread that has a Young's modulus of 4.5 × 10° N/m² and a radius of 13 × 10-“ m. Suppose that a 95-kg person is hanging vertically on an aluminum wire. What is the radius of the wire that would exhibit the same strain as the spider's thread, when the thread is stressed by the full weight of the spider?

0.7 cm A disk between vertebrae in the spine is subjected to a shearing force of 633 N. Find its shear deformation taking it to have the shear modulus of 1.00 x 109. The disk is equivalent to a solid high and 5.0 cm in diameter. N m² S i 2 E Ax = μη

A 1.25 m long cable has a diameter 3.50 mm with a Young’s Modulus, E, of 9.75 x 109 N/m2 . When the wire is placed under tension, it experiences a stress of 202.52 x 106 N/m2 , the length of the cable extends by 36.35 mm. Calculate the force that the cable experiences under tension and the strain energy density (U/V) due to deformation. Give your answers in newtons (N) to 2 decimal places for the force; and in joules per cubic metre (J/m3 ) for the strain energy density to 2 decimal places. Assume the cable is solid and the material is homogeneous.

g) A wire has a diameter of 5 mm, original length is 20m. Applying a force of 40 N causes the wire to extend by 0.5 mm. Calculate the following: i) The tensile strength ii) The tensile strain iii) Young's Modulus
