12. You have a balloon that is tethered to a string which is anchored to the floor with a weight. Assume that the load on the string is L and that the 2 m string extends by 1 cm under the load. (A) What is the mechanical deformation that the string is experiencing? Draw a diagram with relevant quantities marked to describe the mechanical deformation. (B) What is the strain that the string experiences? (C)You take the string to the lab and do a tensile test. Sketch a stress-strain curve that you expect to see if the string behaves like a linear elastic material until load 2L, and then undergoes a plastic deformation.
