- A certain wire stretches 1.2 cm when outward forces with magnitude F are applied to each end. The same forces are applied to a wire of the same material but with six times the diameter and 12 times the length. The second wire stretches in cm:Kendra holds the end of a rope that is .5 kilograms and .60 meters long, while her friend Lupita holds it on the other end, with a force of 150 N. What is the torque that Kendra withstands? The rope has a Young's Modulus of 55x10^8 Pa, unfortunately, it cannot stretch more than 3 cmfrom 600 Newtons of tensile force, or else it would break apart. Would it break apart in this case?A cylindrical steel rod is originally 250 cm long and has a diameter of 0.257 cm. A force F is applied longitudinally and the rod stretches 0.910 cm. What is the magnitude of the force? F = N
- A vertical steel girder with a crosssectional area of 0.15 m2 has a 1550 kg sign hanging from its end. (Ignore the mass of the girder itself.) If the girder is 9.50 m long, how much is it lengthened? Note that the Young's modulus =200x10 9 * O 8.4x10 6m 4.4x10 -6m O 4.8x10 -6m O All answers are wrongA force compresses a bone by 1.0 mm. A second bone has the same length but twice the cross-sectional area as the first. By how much would the same force compress this second bone? 0.50 mm 1.0 mm 2.0 mm 4.0 mm 8.0 mm
