pulley
The force on a rope is typically determined by the tension applied to it. This tension arises from the pulling or stretching of the rope, causing the rope to support a load or resist a force. The force on a rope can be calculated using principles of Newton's laws of motion and equilibrium.
The reaction force to you pulling on a rope is the tension force exerted by the rope in the opposite direction. This tension force is equal in magnitude and opposite in direction to the force you apply to the rope.
An example of a pulling force is when you use a rope to pull a heavy load towards you. Another example is the force of gravity pulling objects towards the earth's surface.
To make a single fixed pulley work, you need to apply an input force to one end of the rope. The pulley redirects the force in the opposite direction, allowing you to lift or move an object with less effort. The mechanical advantage of a single fixed pulley is 1, meaning the output force equals the input force.
i have a great scince teacher and she said it means a levers i hope it helped you prove or do your homework
I am not sure what you mean by "a surface that re-directs force" but you could use a pulley to redirect a force from a rope.
Is a pulley

A rope winds around the pulley so that two ropes hang downwards. Using one side of the rope to apply force causes the pulley to rotate and redirect the force, moving the load upwards even though the pull is applied downwards.

A smooth and flat surface, like a gym floor or pavement, is best for using a jump rope.
A tendon can be likened to a pulley because it serves to transmit force from muscle to bone. Just as a pulley redirects force and aids in lifting heavy objects, tendons help muscles generate movement in the body.
The reaction force to you pulling on a rope is the tension force exerted by the rope in the opposite direction. This tension force is equal in magnitude and opposite in direction to the force you apply to the rope.
A block of mass M is pulled with a rope on a frictionless surface If a force P is applied at the free end of the rope what will be the force exerted by the rope on the block if the mass of rope is m? Equation#1: Force = mass * acceleration The force P pulls a total mass of (M + m) accelerating both masses at the same rate. Equation #2: P = (M + m) * a Equation #3: a = P ÷ (M + m) At the point where the rope is attached to the block, the block of mass M feels a force making it accelerate at a rate of a = P ÷ (M + m). The force required to make at block of mass M accelerate at a rate of a = P ÷ (M + m) can be determined by equation #4. Equation #4: F of block = mass of block * [P ÷ (M + m)].
To move a wagon up a ramp using a rope and a pulley, you would first attach one end of the rope to the wagon and the other end to a pulley positioned at the top of the ramp. By pulling down on the free end of the rope, the pulley system would create a mechanical advantage, allowing you to lift the wagon more easily. The pulley redirects the force you apply, making it easier to move the wagon up the incline. This setup reduces the effort needed to overcome gravity and friction.
