The 10 kg slender bar AB, shown in the figure, has a length of 2 m. A block of negligible mass, pinned freely to end A, is confined to move along the smooth circular groove with its centre at O. End B rests on the floor for which the coefficient of kinetic friction, µk = 0.4. If the bar is released from rest when θ = 30 degrees
*********MASS IS 10 KG, NOT LBS**********

*********MASS IS 10 KG, NOT LBS**********
a)draw the free body, kinematic and kinetic diagrams for the bar,
b) set up a global reference axes system, and write down the relevant
kinetic and kinematic relationships with respect to reference axes
system, and
c) determine the angular acceleration of the bar and the reaction forces
at ends A and B.
