Document Summary
In order to punch a hole in the steel plate, the superhero must punch out a plug with cross- sectional area, , equal to that of his fist and a height t equal to the thickness of the steel plate. The area of the face that is sheared as the plug is removed is the cylindrical surface with radius r and height t as shown in the sketch. As a liquid, the water occupied some volume. As ice, the water would occupy volume 1. 090vl if it were not compressed and forced to occupy the original volume. Consider the pressure change required to squeeze ice back into volume. The tension and cross-sectional area are constant through the entire length of the rod, and the total elongation is the sum of that of the aluminum section and that of the copper section. where with.
