Those kinds of devices are called machines.
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 pulley system is a machine that changes the direction of the force needed to do a task without changing the size or force needed. It allows you to pull downwards to lift an object upwards.

a device that helps make work easier by changing the size or direction of force
A device that helps make work easier by changing the size or direction of force is a machine. A simple machine has only one movement. A wedge has a moving inclined plane. A inclined plane has a sloped surface.
It is called a machine.

Yes, force has both size and direction. The size of a force is measured in units such as newtons, while the direction indicates the way in which the force is applied. It is important to consider both size and direction when describing or calculating forces in a physical system.
A pulley is a simple machine that changes the direction of the force required to perform a task without changing the amount of force needed. By redirecting the force, pulleys make it easier to lift or move heavy objects.
The size and direction of an object can be changed by applying a force to it. Forces can cause objects to accelerate, decelerate, change shape, or change direction. Additionally, factors such as temperature, pressure, and external influences can also affect the size or direction of an object.
