Levers and pulleys are both simple machines that can be used to multiply force or change the direction of a force. While levers involve rotating around a fixed point, pulleys use a wheel and axle mechanism to redirect force applied to a rope or cable. Both can be used to make work easier by increasing mechanical advantage.
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).
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.
A third class lever pulley is a type of pulley system where the effort force is applied between the load and the fulcrum. This arrangement gives a mechanical disadvantage, meaning that a greater effort force is required to move the load. Third class lever pulleys are commonly used in situations where speed and distance are more important than the amount of force needed.
The relationship between pulley torque and the efficiency of a mechanical system is that higher pulley torque can lead to lower efficiency. This is because higher torque can result in more friction and energy loss in the system, reducing its overall efficiency.
No, a fulcrum is the pivot point for a lever
A lever is an adaptation of a stick or tree branch. A pulley is an adaptation of a wheel.
maybe the pulley but not the lever he invented the pulley but not the lever
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).
No, The Greek Scientist who founded the Lever and Pulley is Archimedes.
there are two kinds of pulleys. A movable pulley and a fixed pulley. But a wheel and axle have a lever and a inclined plane. [someone] :]

Pliers are a lever
wedge lever
lever at crank, connected by chain to lever at rear wheel
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.
A pulley has an axle or pivot just like a lever has a fulcrum. Just as a lever tilts across a fulcrum and the fulcrum bears all the weight, a pulley rotates around its pivot/axle the same way. So in essence, a pulley is a lever wrapped into a wheel, with its fulcrum in the center.
the relationship between them is that the load carries it self and the lever holds its self in place
