Transcribed Image Text:A rectangular plate has width and breadth
of 400 cm and 500 cm, respectively. An
applied torque of 300 N.m gives the plate
an angular acceleration of 15 rad/s² about a
perpendicular axis through the centre of the
plate.
1) Calculate the rotational inertia of the
plate about that axis. [
2) Determine the mass of the plate.
3) Suggest the radius of a solid sphere that
has the same mass and rotational inertia as
that of the plate. [
