if the period of oscillation T is directly proportional to the following radius a, density, and surface tension Y use dimensional analysis to deruve the correct relationship between the quantities

Aknife blade is a(n) a. lever b. screw c. wedge d. inclined plane

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
