Question

Rigid rods of negligible mass lying along the y axis connect three particles (as shown). The system rotates about the x axis with an angular speed of 2.00 rad/s. Find (a) the moment of inertia about the x axis, (b) the total rotational kinetic energy evaluated from (1)/(2) 2, (c) the tangential speed of each particle, and (d) the total kinetic energy evaluated from ∑(1)/(2) miυi2 . (e) Compare the answers for kinetic energy in parts (a) and (b).
