Question

You pull down on a rope to raise a flag on a flag pole which describes why the rope and the flag pole act as a machine

A-they change the direction of the forces
B-they increase the distance over which the force acts
C- they decrease the distance over which the force acts

Answer 1

A-they change the direction of the forces

Step-by-step explanation:

Answer 2

Answer: A-they change the direction of the forces

Explanation:

Any device which makes our work simpler is known as a machine. A machine may increase the amount of output force which is determined by its mechanical advantage or a machine changes the direction of the force.

In the given situation the input force acts in the downward direction to pull the rope. The output force acts on the flag being pulled upwards at the other end. Thus, the direction of the forces varies. Correct option is A.
