10 Nm is the smallest amount of torque that may be applied to a rigid body.
Torque is the force's twisting action about the axis of rotation. Torque is the term used to describe the instant of force. It is the rotational equivalent of force. Torque is a force that acts in a turn or twist.
The amount of torque is equal to force multiplied by the perpendicular distance between the point of application of force and the axis of rotation.
The value of torque;
[tex]\rm \tau= F \times d \\\\ \rm \tau= 100 \ N \times 0.1 \ m \\\\ \tau= 10 \ Nm[/tex]
Hence, the minimum magnitude of torque that can be exerted on a rigid body will be 10 Nm.
