Awheel free to rotate about its axis that is not frictionless is initially at rest. a constant external torque of +46 n·m is applied to the wheel for 17 s, giving the wheel an angular velocity of +580 rev/min. the external torque is then removed, and the wheel comes to rest 120 s later. (include the sign in your ) find the moment of inertia of the wheel.(b) find the frictional torque, which is assumed to be constant.

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.
