What pulley can lift weight with the least amount of force?
A fixed pulley can lift weight with the least amount of force. It changes the direction of the force needed to lift the weight but does not provide any mechanical advantage.
24lbs of weight hanging on a pulley how much force is needed to lift the weight?
If the pulley is fixed (hanging from the ceiling), and the rope passes over it, then 100 lbs of force is required. If the rope is fixed to the ceiling and passes under the pulley (which is fixed to the load), then 50 lbs of force is required.
What is the relationship between the weight of an object and the pulley tension required to lift it?
The weight of an object is directly proportional to the pulley tension required to lift it. This means that as the weight of the object increases, the tension in the pulley system needed to lift it also increases.
How much weight does a fixed pulley take?
A fixed pulley does not take any weight itself. It redirects the force applied to it, making it easier to lift a heavy object by changing the direction of the pull.
How much effort force would you use to lift a 300 kg weight with a fixed pulley?
a lot

What is the significant benefit of a compound pulley system?
it is that a person does not ave to lift as much weight
What is the relationship between the weight of an object and the pulley tension required to lift it?
The weight of an object is directly proportional to the pulley tension required to lift it. This means that as the weight of the object increases, the tension in the pulley system needed to lift it also increases.
What are some example sentences for 'pulley'?
A pulley is used to move a heavy weight. You can use a pulley to lift something that you can't lift alone.
How much effort force would you use to lift a kg weight with a fixed pulley system?
a lot
How do lifts and elevators work?
The cabin of the lift is raised (and lowered) by a pulley. The pulley has a counterweight, which weighs as much as an empty cabin. Therefore, the wheel at the top of pulley does not need to lift the entire weight of the cabin - just the extra load in the cabin.
How much weight does a fixed pulley take?
A fixed pulley does not take any weight itself. It redirects the force applied to it, making it easier to lift a heavy object by changing the direction of the pull.
How much effort force would you use to lift a 300-kg weight with a moveable pulley system?
150
How much effort force would you use to lift a 300 kg weight with a fixed pulley?
a lot
Does weight affect a pulley?
Yes, weight has a huge effect on a pulley system. The amount of weight being moved or lifted directly affects how well the pulley works, and too much weight can break it altogether. Weight is also the main leverage in a pulley system.
How much effort force would you use to lift 300 kg weight with a fixed pulley system?
a lot
