The disk has a mass of 20 kg and is originally spinning at the end of the massless strut with an angular velocity of = 60 rad/s. If it is then placed against the wall, for which A = 0.3, determine the time required for the motion to stop. What is the force in strut BC during this time?

[A]. t = 3.11 s, FBC = 193.1 N
[B]. t = 2.65 s, FBC = 227 N
[C]. t = 5.30 s, FBC = 227 N
[D]. t = 6.21 s, FBC = 193.1 N

Answer: Option A
