Answer 1

Answer:

The diagram shows a wire of diameter D and length L that is firmly clamped at one end between two blocks of wood. A load is applied to the wire which extends its length by x. A second wire is made of the same material, but of diameter 2D and length 3L. Both wires obey Hooke's law.
