A lever is a device that uses a single moment to change the size or direction of a force. By applying a force at one point on the lever, a larger force can be exerted at a different point on the lever.
A pulley is a device that changes the size and direction of the force with only one movement. It allows you to lift heavy objects by pulling down on a rope that is wrapped around the pulley, changing the direction of the force needed to lift the object.
A lever is a simple machine that changes the direction or magnitude of the force applied to it. It can be used to increase the motion or force output from the input work.
A simple machine, such as a lever or pulley, can change the magnitude or direction of a force. These devices allow for easier movement of objects by applying force in a different way.
Force changes either the speed or the direction of motion, or both.
A simple machine, such as a lever or pulley, can change the direction or strength of a force by providing a mechanical advantage. These devices allow for easier movement or lifting of objects by distributing the force applied over a greater distance or by altering the direction of the force.

changes the direction of a force
Force changes either the speed or the direction of motion, or both.
A simple machine, such as a lever or pulley, can change the direction or strength of a force by providing a mechanical advantage. These devices allow for easier movement or lifting of objects by distributing the force applied over a greater distance or by altering the direction of the force.
moment depends upon the force and the perpendicular distance between the force and the point where we are finding the moment. so when moment changes either the force will change or the perpendicular distance will change.
To calculate the moment force about a pivot, you multiply the force applied by its distance from the pivot. The formula is: Moment force = Force × Distance. Make sure to consider the direction of the force and apply the right-hand rule for the vector direction.
when it changes its direction
A machine that changes only the direction of force has a mechanical advantage of 1. This is because it does not multiply the input force, but rather changes its direction to make work easier.
A fixed pulley changes the direction of the input force without changing its magnitude. It can make it easier to lift or move an object by allowing the force to be applied in a more convenient direction.
