Question 44





Rigid rods of negligible mass lying along the y axis connect three particles (Fig. P10.44). The system rotates about the x axis with an angular speed of wi = rad/s. Find
(a) the moment of inertia about the x axis,
(b) the total rotational kinetic energy evaluated from 1 2Iv2 ,
(c) the tangential speed of each particle, and
(d) the total kinetic energy evaluated from a12mivi2
(e) Compare the answers for kinetic energy in parts (a) and (b).
