,SOLUTION
Resonance is a phenomenon that occurs when the matching vibrations of another
object increase the amplitude of an object’s oscillations.
Resonance in physics is defined as follows:
A phenomenon in which an external force or a vibrating system forces another system
around it to vibrate with greater amplitude at a specified frequency of operation.
SOLUTION

There are indeed several sources of torque on an aluminum disk in an experiment. Two
examples:
• Frictional Torque: This type of torque arises when two surfaces in contact with
each other experience a frictional force. This can happen when disk is rotating on
a surface or when it is in contact with another object. Frictional force creates a
torque that opposes the rotational motion of the disk.
• Gravitational Torque: This type of torque arises due to gravitational pull of an
object. If disk is off-center relative to axis of rotation it will experience a
gravitational torque that acts perpendicular to the disk. The gravitational torque
will cause the disk to tilt or rotate changing its orientation in space. This can be
especially significant if disk is rotating at a high speed.
• According to the given question; we have to mention two source of torque on
the aluminium disk.
