When a pulley is used to lift a box, the person pulling the rope is applying mechanical energy which is then transferred to the pulley system. The pulley system reduces the amount of force needed to lift the box by distributing the work over multiple ropes and wheels. In the process, some of the energy is dissipated as heat due to friction between the moving parts.
The amount of weight a pulley can lift depends on factors such as the design of the pulley system, the strength of the rope or cable used, and the efficiency of the pulley itself. However, a single fixed pulley does not provide any mechanical advantage and can only lift as much weight as is being applied to it.
The amount a pulley can lift depends on its design, the strength of the materials used, and the mechanical advantage it provides. Generally, a pulley system can reduce the amount of force required to lift an object by half or more, making it easier to lift heavy loads.
Reducing friction on a pulley can make it work better by allowing the system to move more smoothly and efficiently. This results in less energy being wasted as heat and more of the input energy being used to lift or move objects. Additionally, it can reduce wear and tear on the pulley system, extending its lifespan.
By using a pulley, Erin can reduce the amount of force needed to lift the crate. If Erin uses a single fixed pulley, she would still need to apply 50 newtons of force to lift the crate, but it would require less physical effort due to the change in direction of the force. If she uses a more complex pulley system, like a block and tackle, she could further reduce the amount of force needed, making it even easier to lift the crate.
A pulley can be used to lift heavy objects, lower objects, or to change the direction of a force. It is commonly used in various applications such as construction, manufacturing, and transportation to make tasks easier and more efficient.
A pulley is used to move a heavy weight. You can use a pulley to lift something that you can't lift alone.
I used a pulley to lift the large log.
The pulley was discovered to lift objects that would otherwise be too heavy to lift. Much in the way a crane is used to lift cargo onto ships.

A device used to lift something heavy. By using a pulley, you half the effective weight.
connetions academy huh?

The rack is used to hang laundry indoors. The pulley system is used to lift the rack to a higher elevation in the room where usually the warmer air is located.
