Determine the kinetic energy of the assembly of Prob. 18.1.
Prob. 18.1. Two uniform rods AB and CE, each of mass 1.5 kg and length 600 mm, are welded to each other at their midpoints. Knowing that this assembly has an angular velocity of constant magnitude ω = 12 rad/s, determine the magnitude and direction of the angular momentum HD of the assembly about D.
