Two first graders (Mike and Tim) are on opposite ends of a seesaw. Why does Mike not go flying off his end of the seesaw when Tim pushes down on the other end? Tim is not applying enough force to move Mike's mass that much.
Tim is not applying enough force to move Mike's mass that much.

The strength of Tim's force is not as great as the force of gravity pushing Mike down.

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.
