Question
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
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,
c) determine the angular acceleration of the bar and the reaction forces
at ends A and B.
