A pullkey allows for a single rope to change the direction of force, reducing the effort needed to move an object. This is more efficient than using two separate pulleys, as it eliminates the need for multiple ropes and decreases the amount of friction and energy expended.

How does a fixed pulley make work easier?

A fixed pulley does not make the force applied easier, it changes the direction of this force. For example, instead of bending over and lifting and object, a fixed pulley lets you lift it by pulling down on a rope.


How does a single pulley make work easier?

A single pulley changes the direction of the force needed to lift an object, making it easier to lift by allowing you to pull downwards rather than upwards. It does not reduce the amount of work needed, but it helps in exerting the force in a more convenient direction.


Is a single fixed pulley superior than a single movable pulley?

A single movable pulley is typically considered superior to a single fixed pulley because it reduces the amount of force needed to lift an object. The movable pulley changes the direction of the force applied, making it easier to lift heavy objects.


Why it is easier to lift the same load by using three -pulley system than two-pulley system?

A three-pulley system allows the load to be distributed among three supporting strands, making it easier to lift the load as each strand bears less weight compared to a two-pulley system where the load is evenly distributed between only two strands. The mechanical advantage of the three-pulley system reduces the amount of force required to lift the load, making it easier to lift.


WHY IS MOVEABLE PULLEY MORE USEFUL THAN FIXED PULLEY?

A moveable pulley is more useful than a fixed pulley because it allows for a mechanical advantage, making it easier to lift heavy loads. With a moveable pulley, the effort force is reduced as the load force is distributed between the two sections of the rope supporting the load. This results in less force required to lift the load compared to using a fixed pulley.

When a fixed pulley is used what does the force and the load do?

In a fixed pulley system, the force required to lift the load remains the same as the weight of the load. The pulley simply changes the direction of the force needed to lift the load, making it easier to lift by pulling downwards rather than lifting upwards.


What is the problem for turning milk into plastic?

It is much easier to make plastic from petroleum than from milk, just as it is much easier to make ice cream from milk, than from petroleum.


What is the mechanical advantage of the pulley system?

The mechanical advantage of a pulley system is the ratio of the output force to the input force. It is calculated by dividing the load force by the effort force required to lift the load. The mechanical advantage of a pulley system can be greater than 1, making it easier to lift heavy objects.
