Respuesta :

The force, F = 30 N, radius, r = 0.04 m

The torque will be

[tex]\begin{gathered} \tau=F\times r \\ =30\times0.04 \\ =\text{ 1.2 N m} \end{gathered}[/tex]

The direction of the torque will be such that the thumb will be center and curl the fingers in the direction of the force.

Thus, the torque will be 1.2 N m in the clockwise direction.
