Transcribed Image Text:A uniform hemisphere of mass m = 5 kg. and radius r = 0.5m. is released from
rest on a horizontal surface in the position when OG is horizontal as shown in
the figure below. The mass centre G of the hemisphere is at a distance (3/8)r
from point O and its mass moment of inertia about O is ( ) 2 1 0 = 2/ 5 mr . If
the friction between the hemisphere and the horizontal surface is sufficient to
prevent slipping,
(3/8)r
Hand draw the free body, kinematic and kinetic diagrams for the hemisphere (shown above)
showing all the forces and moments acting on it at the initiation of its motion
