Athin uniform rod (length = 1.2 m, mass = 2.0 kg) is pivoted about a horizontal, frictionless pin through one end of the rod. (the moment of inertia of the rod about this axis is ml2/3.) the rod is released when it is being held up above the level of horizontal and when it makes an angle of 37° with the horizontal. what is the angular acceleration of the rod at the instant it is released? (in units of rad/s/s )
Answers: 1
is given by
where F is force and r is perpendicular distance
where 
is the angle of inclination
where I is moment of inertia and a is angular acceleration
and already I is given as 
hence
