60/4 pounds
or 15 pounds
Any force that is more than 50 pounds will lift a 50-pound object. The greater the force is, the greater the object's upward acceleration, and the sooner the object will reach any given height.
A system with a mechanical advantage greater than 1 will require a smaller input force to lift a load. To lift a 2500 N load with the smallest input force, a pulley system with a mechanical advantage of 2 would only require an input force of 1250 N.
To calculate the input force needed to lift a stone slab weighing 2500 N with a mechanical advantage of 10, you would divide the weight of the slab by the mechanical advantage. So, the input force required would be 250 N (2500 N / 10).
A pulley system with a mechanical advantage of 4 would require the least amount of effort force to lift a load. This means that for every 4 units of load force, only 1 unit of effort force is needed.
To lift a 200-pound object using a double pulley system, the force needed would need to be equivalent to half the weight of the object. This is because a double pulley system reduces the amount of force required by distributing it evenly between the two strands of the rope. Therefore, the force needed would be 100 pounds.

If a force of 30 pounds lifts a load of 120 pounds, it sounds to me like the mechanical advantage must be 4, regardless of what kind of contraption you used to accomplish it.
No, mechanical advantage has no units, it is simple the ratio of an output quantity, such as force, to the input quantity. For example if it takes 10 pounds to lift a 50 pound object, the mechanical advantage is = 5

If the pulley system has a mechanical advantage of 3, then the force required to lift the 50N load would be 50N divided by 3, which equals 16.67N.
11,000/20=550newtons
When a machine has a certain mechanical advantage, it means that it can multiply the input force applied to it. Mechanical advantage is calculated as the output force divided by the input force required to lift a load. Machines with a mechanical advantage greater than 1 make it easier to lift heavy objects.
Mechanical Advantage. Using a lever of appropriate size you could lift a 500 pound load with just 50 pounds of force. The distance from the weight to the Fulcrum would have to be 1/10th the distance from the Fulcrum to you, pushing down with 50 lbs 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.
