A fixed pulley with a rope passing through the pulley. The load is attached to one end and a force is applied to the other end.
No, a pulley is not a third class lever. A pulley is a simple machine that consists of a wheel with a groove around its circumference, used for lifting or moving objects. Third class levers have the input force between the fulcrum and the output force.
Single Pulley
A simple pulley is a rope (or chain or belt) with one wheel this may be a class 1 or class 2 pulley.For a class 1 pulley, the pulley is stationary and the force applied to the rope is in the opposite direction as the movement of the object.For a class 2 pulley, the pulley is attached to the moving object and the force applied to the rope is in the same direction as the motion of the object.A compound pulley, consisting of an arrangement of more than one simple pulley, provides many other possibilities with the direction of force either the same direction or the opposite direction of the motion of the object being moved.
A pulley is a class 1 lever because the fulcrum (pivot point) is between the load (object being lifted) and the effort (force applied to lift the load).
Simple Answer:A movable pulley is a class 2 pulley and does not change the direction of the force applied to the object to be moved.Explanation:A simple pulley may be arranged so the force is applied in the direction of motion of the object that is moved or in the opposite direction.A simple pulley with one wheel may be a class 1 or class 2.For a class 1 pulley, the pulley stationary and the force applied to the rope is in the opposite direction as the movement of the object.For a class 2 pulley, the pulley is attached to the moving object and the force applied to the rope is in the same direction as the motion of the object.A compound pulley, consisting of an arrangement of more than one simple pulley, provides many other possibilities with the direction of force either the same direction or the opposite direction of the motion of the object being moved.
A 1st class pulley is when the axis or fulcrum is located between the load and the effort. This type of pulley can change the direction of the force applied to lift an object. It is often used in flagpoles and some types of lifting systems.

No, it's a 2nd class lever.
yes
Fixed pulleys are similar to, and are considered by many to be, first class levers. In a first class lever, the fulcrum of the lever is placed between the load (resistance) and force (effort). In a fixed pulley, this is essentially the same. Picture a piece of rope hanging from a ceiling from one end, and with you holding the other end. A weight on a pulley is placed in the middle. Now, if you pull up on the rope, the weight rises, just like with a first class lever. Since the load is between the fulcrum (the pulley) and the effort (you pulling up), the fixed pulley acts like a first class lever.

no but a first class lever is
