Under the right conditions, it is possible, due to surfacetension, to have metal objects
Chapter 1, Problem 1.126(choose chapter or problem)
Under the right conditions, it is possible, due to surfacetension, to have metal objects float on water. (See Video V1.9.)Consider placing a short length of a small diameter steel ( = 490lb/ft3) rod on a surface of water. What is the maximum diameterthat the rod can have before it will sink? Assume that the surfacetension forces act vertically upward. Note: A standard paper cliphas a diameter of 0.036 in. Partially unfold a paper clip and see ifyou can get it to float on water. Do the results of this experimentsupport your analysis?
