Transcribed Image Text:

The 12-kg homogeneous plank of length = 11.2 m and width d= 0.4 m rotates about trestle B and strikes trestle A without rebounding. If the angular velocity of the plank, just before the impact, is 1.6 rad/s counterclockwise, determine the angular speed of the plank just after impact. The distances from the tips of the plank to the trestles are al and bl, where a = 0.33 and b = 0.15. al A L(1-a-b) L(1-a-b) B bl The 12-kg homogeneous plank of length = 11.2 m and width d= 0.4 m rotates about trestle B and strikes trestle A without rebounding.
