Does the position of the fulcrum affect the force necessary to lift a weight?
Yes, the position of the fulcrum affects the force required to lift a weight. Placing the fulcrum closer to the load reduces the effort needed to lift the weight. Conversely, placing the fulcrum further from the load increases the force needed to lift the weight.
How much force is needed to lift 200 pounds of weight?
To lift 200 pounds of weight, you would need to apply a force equal to the weight being lifted, which in this case is 200 pounds. This is because the force needed to lift an object against gravity is equal to its weight.
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.
How does a movable pulley reduce the input force needed to lift a weights?
A movable pulley reduces the input force needed to lift weights by distributing the weight between two strands of rope. As the pulley moves up, the weight on one side is balanced by the force exerted on the other side, effectively halving the force needed to lift the weight. This mechanical advantage makes it easier to lift heavy objects.
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.
How much work can a person do to lift a 200-N weight 1.5m above his head?
Work = Force * Distance Force = 200N (gravity already taken into account because of N) Distance =1.5m Work = 200N * 1.5m Work = 300N*m = 300 Joules

A lever is used to lift a load weighing 200N The force needed was 600N What is the mechanical advantage of this first class lever?
3 x 200 N = 600 N.
How much down force is needed to lift a helicopter?
The same force as the weight of the helicopter and its crew and cargo.
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.
The force lever uses to lift a load is?
determined by the length of the lever arm and the weight of the load. The longer the lever arm, the less force is needed to lift the load. The force needed is inversely proportional to the length of the lever arm.
How do you find the minimum amount of force needed to lift an object?
The minimum amount of force needed to lift an object can be found by calculating the object's weight using the formula F = m * g, where F is the force, m is the mass of the object, and g is the acceleration due to gravity. This force must be greater than or equal to the weight of the object to lift it off the ground.
If the coefficient of static friction is 0.3 how much more force is needed to lift the object than start it sliding?
To lift an object, you need to overcome its weight, whereas to start it sliding you need to overcome both its weight and the static friction force. The force needed to lift the object would be equal to its weight, whereas the force needed to start it sliding would be the weight of the object plus the product of the coefficient of static friction and the weight of the object. Therefore, the force needed to lift the object would be less than the force needed to start it sliding by the weight of the object multiplied by the coefficient of static friction.
What force is required to lift something on a pulley?
The force required to lift an object using a pulley system depends on the weight of the object being lifted. The force needed is equal to the weight of the object being lifted plus the force required to overcome any friction in the pulley system. The mechanical advantage provided by the pulley system can help reduce the amount of force needed to lift the object.
