A meter stick on a horizontal frictionless table top is pivoted at the 80-cm mark. A force is applied perpendicularly to the end of the stick at 0 cm, as shown. A second force (not shown) is applied perpendicularly at the 100-cm end of the stick. The forces are horizontal. If the stick does not move, the force exerted by the pivot on the stick:

Respuesta :

If the forces are horizontal, they cannot cause rotation. The pivot will have to exert 0 N of force in order to prevent rotation.
