Question
![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. [](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe023b7e8-0e7a-446d-a3c0-93a33f7c8ac8%2Fb46de048-12d9-4271-b1fb-d9067fdf4408%2F38d00za_processed.jpeg&w=3840&q=75)
