Respuesta :

The force needed to loosen the screw is 3350 N

Explanation:

We know that

       Torque = Force x Perpendicular distance

Here we need to find force, torque and radius are given,

For a screw radius is similar to perpendicular distance

Perpendicular distance = 2 cm = 0.02 m

Torque = 67 Nm

Substituting in

         Torque = Force x Perpendicular distance

          67 = Force x 0.02

         Force = 3350 N

The force needed to loosen the screw is 3350 N
