WebMost solids initially deform elastically; that is to say, they return to their original shape when the load is removed. Rigid materials such as metals, concrete, or rocks sustain large forces while undergoing little deformation, but if sufficiently large forces are applied, the materials can no longer sustain them by elastic deformation alone. http://coastalchange.ucsd.edu/st3_basics/waves.html

"WebThe lead-line was the original depth sounder. Cylindrical in shape with a long marked line--it had a hollowed-out bottom. The boatswain would smear a coat of tallow in the hollow so that a sample of the bottom would stick to the lead. Then, he was sent as far forward as possible to "cast the lead".
