Pulleys are used to change the direction of a force, making it easier to lift heavy objects by applying less force over a longer distance. They also allow for the lifting of objects to higher heights by distributing the load across multiple ropes or cables. Overall, pulleys are essential tools for mechanical advantage in various applications, such as construction, manufacturing, and transportation.

How much effort is needed to lift a 75 N weight using the pulley system?

If you are talking about a simple pulley with the pulley attached and load rope attached to the object then you will need a little more than 75N of force. Lifting an object (at a constant velocity) requires a force equal but opposite the weight of the object. With any simple machine you will need to do more work to overcome friction. If you were to use a single pulley with the pulley attached to the object then you will need a little more than 37.5 N. If you were to use a multiple pulley system then you would need to know the mechanical advantage of the pulley system.


How do you measure pully size?
